I tried to upgrade 'lhaven' more...

...was less than successful.

Back following the icepocalypse, I resurrected 'lhaven' by changing its motherboard. The new motherboard was an upgrade to the old one, but I wasn't taking advantage of any of it. But, in my mind I thought that someday I might.

Having finally upgraded the OS from RedHat 7.3 to Ubuntu 10.04....and being able to participate in all BOINC projects again, I decided that I might look at upgrading it finally.

So I went looking for the fastest FSB 333MHz CPU that I could put into it. And, went looking on eBay for one. After a few unsuccessful attempts, I went and bought an Athlon 3000+ (and an Athlon 2400+). And, while I was on there, I got a new CPU Heatsink and Fan and a 1GB stick of DDR333 memory.

I wasn't sure what kind of memory was in the machine, but somehow I thought it to be a 1GB stick of DDR333 (since I for some reason had an extra DDR333 1GB stick that I gave away recently)....but memory told me the machine had two slots, so I'm not sure why I didn't upgrade the memory to more than 1GB...

Well, turns out my memory was faulty (as was lshw)...the machine had two 512MB DDR226 memory sticks. Which I makes sense, since the old CPU was FSB266 (a 2000+)....guess that means I shouldn't have given away that 1GB stick of DDR333.

What I did was upgrade the memory to 1.5GB by putting the new 1GB DDR333 stick in the first memory slot, and a 512MB DDR400 stick in the second slot. I then looked at the CPU.

First I put the Athlon 3000+ in....and the new CPU heatsink/fan. It is a touch bigger, actually its a lot bigger than the old....not quite compatible with my case...though it should be a simple enough mod once I get everything working again. Except I didn't. No POST.

lhaven upgraded

AKA the end of RedHat 7.3.

For sometime, I have thought that it was time to upgrade 'lhaven' to a more modern release of Linux.

For the longest time, 'lhaven' has been running RedHat 7.3 (it was 7.2, but then I discovered Fedora Legacy...and they were providing patches for RedHat 7.3) And, there are still some production servers running this release, but I no longer have to support them...as I no longer work there.

The problem was that I had compiled a lot of custom apps over the years, that would be difficult to upgrade to newer distro/release of Linux. Since they were done without though to going to a different distro. 'lhaven' did used to run older versions of RedHat, and had been upgraded to where it stopped. But, to go to another distro would require a major effort. And, some of the apps were hard enough to get working to begin with. And, were some what fragile.

'lhaven' has also gone through some hardware iterations. The first major was when the Cyrix 233 that it was one burned up (a transformer had blown a phase, causing really low voltage before it went out....) though more likely it was its return after the outage with none of its fan able to spin. It was working for a while...but then there was smoke, and it all ended.

Got a Duron 800Mhz machine, which grew to an Athlon 2000....and had its motherboard replaced after the icepocalypse. The icepocalpyse was the first time I had to seriously look at upgrading from the old RedHat 7.3....but later I found a compatible motherboard and got the system to boot. The machine I bought at that time became 'orac'.

Later my use of ReplayTVs dropped off, and the one of the main apps that used datadirect for guide data was never successfully updated to support the newer schedules direct service. And, that was one of the things I didn't want to touch. But, now it is gone.

More recently, I started moving some of the other things that ran on 'lhaven' to 'box'. Namely, MRTG and cacti. I also updated all my linux servers to be able to handle mail for my home network, with the local mailboxes on 'box'. Also moved secondary DNS to 'orac' (someday I plan to get fallback DHCP on 'orac', but that'll probably come later.....) During the icepocalypse I had moved DHCP and primary NTP and DNS to 'box'....'lhaven' came back as secondary, because the old 'gumby' was sufficiently broken that I couldn't get it to not require 'lhaven' to function.

So, what I did was install ubuntu-10.04-alternate-i386 to become the new 'lhaven'. Which was the suggested to do RAID at the start, it had been a long time since I had done it, but the last time I had...it was a server install. But ubuntu no longer supports 32-bit hardware as servers, but both 'lhaven' and 'box' are 32-bit machines.

Took some figuring out, but its all done now. Yes, there's a desktop on all my Linux boxes, though 'lhaven' doesn't seem to be really up to the task. The video seems pretty poor and fuzzy compared to the other Linux servers. Perhaps I'll see about replacing its integrated video with an NVidia card of some sort...what that does CUDA, though it'll have to be a PCI card.

Anyways....after the install was done, I installed a few basics...like boinc and called it a night.

declaring 'orac' alive again.

'orac' is back, long live 'orac'.

'orac' had gone away on Thursday, it actually started in Wednesday.... For some unknown reason, I decided to start the upgrade of 'orac' from 8.04LTS to 10.04LTS.

The upgrade seemed to go okay, but when I rebooted....it wouldn't boot. I scrambled around looking for a livecd to boot with....did have any 64bit ones handy and 10.04 was hit and miss on booting. But, I could see vg0 (root, home, swap) with all the livecds except 10.04.

Something about 10.04 didn't like how vg0 was set up. I looked at 'box', which had been running 10.04 for a while and was working. Noticed the main difference between the all the other md's and vg's...was that they weren't fdisk'd md's. When I had originally set up 'orac', I had used a recipe that I had found online on how to do it...since initial install of ubuntu onto Raid wasn't straight forward then. and after md1 was created, I had fdisk'd and then pvcreate/vgcreate, etc. on it.

When I added the other two raid sets....I just pvcreated the md and then used it...no fdisk of the md.

In retrospect I should probably have done a backup of the filesystems while I was running a livecd that could see it....and then perhaps remade the disk and restored into it. But, I didn't and while trying to 'fix' the problem...I corrupted things, and I wasn't able to recover (tried pvcreate -u + vgcfgrestore...but couldn't get the filesystems to come back.

After lots of other attempts and such, I reached the point where I decided things were lost and set on to figure out if I can get back.

backuppc localhost doesn't back up the entire localhost....but it had my home directory backed up (but not all of /home), and it was also backing up /etc. Realized the the one thing it wouldn't get is my crontab files. But I had a dd image of most of the disk (the front part munged)....so I string'd and recovered my crontab from it. And, then set out to install 10.04LTS new.

Since md1 was going to get redone, I decided to redo md0..../boot. Made it a bit bigger than before so that it won't get as crowded from accumulating every new kernel that is released until 12.04LTS comes out. Or some future release needed more than the old size to work. Had actually run into this problem years ago at my previous job....

But, the install kept failing....asking for the disk again....I burned several copies, download from other sources, but no go. So, I tried to 9.10 (thinking I would upgrade to 10.04 immediately), but it also didn't work. Eventually, I found a reference on google that said the 10.04 (and 9.10) installs were picky about what kind of optical drive was being used. It specifically mentioned a particular DVD burner, with 'orac' came with a DVD burner...though I have never used the drive since I did the original install. I tried a USB stick, but couldn't get the machine to use that, and the other external drive I could find was firewire (and there's no BIOS option to boot from firewire).

So, I took apart my machine and the firewire drive. And, put the DVD-ROM drive that was in the firewire enclosure into the machine. The DVD-ROM drive had original come from my circa 2003 Dell, known as 'tardis'.....when I had swapped in a DVD burner.

'box' is the Linux machine that I do cd burning on....and I hardly do DVDs anymore, though I did get a new DVD burner recently for the new 'gumby'.

Anyways....with the 'new' optical drive in 'orac'....I was able to get 10.04LTS to install, and then started the long process of getting my environment back. First problem was backuppc installed with a different uid/gid....so it wouldn't access the old /var/lib/backuppc storage. I opted to fix it the wrong way....that took forever....doing the chown of the files/directories. Should've just changed the uid/gid that backuppc had installed itself as. But, then I tried to do the restore....next problem was sudoers, had forgotten about that.

I then restored /etc to another place, and restored my home directory along side of the one the install had created. When done I swapped my home dir and rebooted. That was a mess. The desktop was all messed up...not just missing apps. Figured it was because the desktop didn't like the old settings....but couldn't find any details on how to upgrade desktop, if I hadn't done an upgrade. I thought other OSs handled this kind of thing. But, not here. So, I flipped back and slowly copied stuff over and restored settings etc. And, reinstalled various apps as I went.

Then I decided that I had made sufficient progress on getting 'orac' configured, that I didn't want to lose things. I had disabled backupc from doing automatic backups during the restore. So I turned it back on and back up the other systems around my home (after first doing a new backup of the new 'orac'). It didn't like .gvfs in my home directory....in old version it complained but continued, in this version it complained and the tar returned an error due to previous error...causing the rest of the backup to fail (the localhost backup does 4 'shares')....so I tweaked the config to get it to work.

The only thing I saw was that it tried to backup 'ulkc', my ubuntu notebook...but it wasn't on at the moment, so it failed. It wasn't going to automatically back up anything else yet, since its one of my blackout periods. So, I started kicking off manual backups of various things, and watched it work. First thing that didn't work was a backup of a windows share. Seems smbclient changed since 8.04LTS...and one of the options was used in backuppc 3.0 didn't work anymore. The new is 3.1, and the default options is minus that one switch....so I matched things up and it did its thing.

The only problem that still didn't work, which I think was the reason I decided to bite the bullet and upgrade to 10.04LTS (to get the newer backuppc) was incremental backup where a very large file has changed since the full. Usually the virtual harddrive of a VirtualBox. Sadly this wasn't fixed in 3.1. Guess I'll have to look at some other way to deal with it. Like exclude it from the regular policy and create a new one that only does that one file....or something. Or maybe ....

I continued to work on other things, as I worked through comparing the old /etc with the new 'orac' /etc. Though interrupted by trying to get file shares working (I had exported my Dropbox directory from another server for access from other computers on my home network....though LAN sync is available now, I haven't undone the stuff yet). And, getting snmpd working again....so I could see the impact to resources and network from all the backuppc jobs running in cacti.

One strange problem is that 'orac' can not access the NFS shares on 'lhaven' (RedHat 7.3), but 'box' can....the only difference I can think of is that 'box' was upgraded to 10.04LTS.... Though I guess it is time I worked on moving services off of 'lhaven' and figure out what I'm going to do to either replace or upgrade it.

The other issue was Handbrake. Originally, I had built it by hand...since there wasn't a package for 64-bit Linux. Though later, I got a newer version via PPA. But, the version that I got via PPA for Lucid didn't work. So, I eventually went and built my own again...from the subversion....my build works....

Hopefully, when 12.04LTS comes along....things'll just upgrade smoothly.

The other odd thing, is that 10.04LTS seems slower....particular in file I/O. The machine seems to really degrade in performance doing a large file copy (as was happening when I was copying directories from my old home dir to the new one.) All the CPUs are bored while this is happening (it's a 2.4GHz Core 2 Quad....with 8G of memory....) Hopefully something that'll resolve itself later?

Did the weekend upgrades...of 'orac' and 'gumby'

So, having returned from a morning trip to the UPS store to pick up some packages and with my knee bothering me more than yesterday...I didn't feel like going out again today. It seemed that there was a good moment do the upgrades I was planning to do.

First upgrade was to 'orac'. It is to upgrade the machine to its 8GB max, from it's current 6GB. So, I popped out the original 2GB the machine came with, and popped in a pair of 2GB DIMMs that I had purchased for this.

At first nothing special to report about it....

So, then took 'gumby' down...so that I could put that 2GB of memory into 'gumby' to take it to 4GB, knowing of course that it is running 32-bit Windows XP. And, while it was open I set in the other upgrade for 'gumby', swap out its DVD-ROM drive for a DVD burner.

No surprise....it didn't see all the memory. Though first thing I noticed was that FreeRAM XP pegged out at 2GB. Guess that's something for the future when I get around to replacing 'tardis'...where I plan to have a 64-bit Windows and tons of memory, etc. Perhaps.

But, checking more...it knows that there's 4GB of RAM in the machine, but it seems to only be letting me use 3GB. I then set about to install the software for the DVD burner. I purchased a retail kit, because I wanted the limited version of software that comes with it. Rather than dig around for the ancient version of software I used to have back then. The limited version is much newer version of Roxio than I had (formerly known as Easy CD Creator). The other computer has a dated version of Nero...I haven't done much in the way of burning in a long time, so it wasn't really a major need to get a new full blown package.

Pretty much just burn the occasional ISO here and there. I wanted to see what this lightscribe stuff is. And, at least have the option...since 'gumby' being more, seems to suggest that I might get back into some of that stuff at some point. Some day I'll buy some blank media to use....other than the spindle of blank CD-Rs that I have nearby (first thing I did burn was the restore iso for 'gumby').

Anyways, while I was using the Plextor software, I checked for updates....first no firmware update, but it found a plexutil update...so I updated it. Running that update, it found a firmware update....so then I did update the firmware. It then reported that it wanted to reboot, so I did that.

The reboot took longer than I expected, partly because I had forgotten that I had scheduled a boot-time defrag of the drives and then it hung during the boot. Not sure if the Plextor stuff has something to do with it (there seems to be something added that does something)...but when I switched to 'orac' to go online to see if I had broken something...I found 'orac' acting a big odd. It eventually locked up completely. But, while I was on 'orac'....'gumby' eventually booted, though with all the shared drives disconnected.

I did notice that after the upgrade, while poking around in the BIOS...that the new PC2-5300 (PNY) memory's SPD was being reported as 800MHz, rather than the expected 667MHz. I wondered if it being in the first bank to the older PC2-5300 (Crucial) in the second bank might be causing some problems....I didn't really feel like undoing the memory upgrades to both systems.

So, I switched the memory around (making sure that it really is alternating sockets, unlike the 'gumby' where they weren't...though the original memory was installed as if it were)

So far 'orac' seems happier....guess we'll see. Did notice that the new memory seems hotter than the old memory....but could just be the difference in packaging.

I then had to reboot 'gumby' after installing the Roxio 10 CE, but it was still slow to boot....did seem it flash some kind of window that I hadn't seen before, so it could be something the Plextor install added to my startup that is contributing to the slowdown in boot.

Guess time will tell....

The process did distract me from the other reboot that I was going to do.... Thought I saw the "Your CPU is lacking expected security protection" while logging into 'box' the other day, and was going to see if there was something I needed to change in its BIOS. Of course, I could've just been confused and confused that from the message that shows when logging into my lucid server VM running in VirtualBox...maybe I'll try that now....

Yay, I used backuppc to restore almost 400GB of data

So, yesterday...I finally decided to buy the new external firewire drive for 'gumby'. Originally the plan was so that I would have retrospect express backups of the system drive, that I could boot from its restore CD and get that part back....with backuppc protecting my data.

On that criteria...I was trying to decide if 500GB was sufficient or perhaps smaller. Since the system drive is 160GB. And, whether USB 2.0 would be sufficient or if I still needed firewire. Old 'gumby' only had USB 1.1 and Firewire 400 ports. New 'gumby' came with USB 2.0 ports and I had added a Firewire 400 card to it.

Looking at the computer store at the K-State Student Union and various online sites (such as NewEgg, Tigerdirect, eBay)....that there wasn't a whole lot of good options in the under $100 mark.

OTOH, I had suspicions that another one of the 300GB firewire drives connected to 'gumby' was failing. I thought maybe I'd get a bigger drive. Looking again at the selection at the K-State computer store, I found a few reasonable choices....1TB, USB2.0/Firewire 400...and one USB2.0/Firewire400/Firewire800/eSata...all under $150 ($125+) So, then I wondered if I should get the Firewire800 option. I knew it was unlikely that I would stick an eSata controller in 'gumby' But, I wondered if I could swap the Firewire 400 card for a Firewire 800. Turns out there's very little in the way of 32-bit PCI Firewire 800 cards out there. And, they weren't cheap....enough for me to jump on. So, I decided that I would just settle for one of the USB2.0/Firewire 400 external drives. Namely the cheapest one at $125....plus it was kind of a known quantity....I already had an older (physically larger) Iomega Ultramax 1TB USB2.0/Firewire drive connected to my other Windows XP box ('tardis')...doing just backups.

I hooked it up and tried to get it going....at first it would detect and then it caused other issues, crashing my computer. Eventually I got the wizard to show up so I could initialize it and reformat it from Mac format to NTFS. The crashing seemed to cause some strangeness with the rest of the system. At first I was cursing having put off re-establishing some kind of Restrospect Express backup on the new 'gumby' (lost the old when the first of external drives died on the old 'gumby' -- used to have Maxtor OneTouch ?? externals...), but then I remembered that I can get the configs / apps restored using backuppc. (Hmmm, wait...I should be able to fix my firefox settings using FEBE. OK)

Meanwhile...I didn't notice those minor app issues until this morning. But, what I started to do was copy data from both externals over to the new drive. At first I was going to come up with a new organization and a single drive letter...when I decided that I would do two partitions, so that they could go into the same original drive letters. And, the old drives would go somewhere else. That way I wouldn't need to reconfigure the apps that look for the data, and backuppc would continue to see things in the same place, etc.

And, the plan was to use the two old 300G drives as the store for local (Retrospect Express) backups.

I debated whether it would be faster to copy between firewire drives or restoring the data using backuppc (both computers have 1Gbit NICs...old 'gumby' only had 10/100). I ended up doing both...restore one drive/partition from backuppc and copying the other drive/partition locally.

As luck would have it....the drive I was copying locally then decided it was time to die. And, things came to a halt.

Piecing back together... ended up restoring both drives from backuppc onto the new 1TB drive.

Once finished, I changed drive letters again...and rebooted to make things work (Windows was hungup about write issues on the failed drive, so it wouldn't let me change drive letters without some force.)

Later I got Retrospect Express working...currently I reformatted both old 300GB drives and have it doing two sets of backups to the drives. I kind of expect that one of them is going to fail me at some point in the future....but it should buy me time until I get the next external drive for this computer.

Running an initial backup right now, and when done I'll create a new restore image....and I should get to burning it after I do the next set of upgrades on this computer.

Oh yeah, yesterday I also finally changed out the USB to PS/2 adapter on it....the old one was annoying because the mouse would stop working periodically....have to be really still for a while and then the mouse would work again. Annoying! New adapter I got is a Trendnet (same brand as my KVM)....so far it seems to be working better, at least in the mouse department. The keyboard has had some issues....stuck repeating 3's.

On tap for next set of upgrades (likely to take place sometime this long weekend), change out DVD-ROM drive for a DVD burner and upgrade the memory to 4GB (after upgrading 'orac' to 8GB and moving the 2GB from there to here).

5-bay RAID and backuppc

Ever since I learned about 5-bay port multiplier SATA enclosures, I've been wanting to get one to play with. And, when I acquired 'orac'...I sought out a port multiplier eSATA adapter to include in the build of the system. And, then waited for support of the adapter in ubuntu. Stopped on 8.04LTS and waited for inclusion in a kernel.

I took a step closer when I finally got the 2-bay enclosure to mirror a pair of drives I had impulsively purchased. Since it worked, I then then bought a 5-bay enclosure (it came up as a NewEgg ShellShocker).

But, after some thought, I decided that what I wanted to do was build a 5 disk RAID5 using 1.5TB drives....so it would get me at least 5TB of real storage. And, set that I would wait until 1.5TB drives were under $100.

In the meantime, I collected a bunch of old SATA drives to see what I trouble I could get into....it didn't last long, as one was definitely dead and two quickly failed. Of course, two of the had been kicked out of RAID1 setups previously, and the other was a failing drive that I replaced/upgraded. So, it was back to waiting.

Eventually, I got 3 Samsung 1.5TB drives through NewEgg ShellShocker. And, I set up a 3 disk RAID5. Sadly, it didn't last very long....one of the drives failed while I was building the array. I exchanged it for a new drive with NewEgg, and waited for it before trying again. While I was waiting, I formatted it a bunch of times and learning about smartctl and various things of drive repair. One of the remaining two original drives, was showing signs of slow death and one unrecoverable sector. When, the new drive arrived...I did a long self test and a quick, but full, format....taking a couple days before I created the 3 disk RAID 5.

Once, that was done, I created a new big filesystem that is /var/lib/backuppc to have backuppc on 'orac'. Initially a 1TB filesystem.

Then one day, the bad happened. A drive on 'gumby' failed. It was time to stop putting off figuring out how to setup backuppc and start putting stuff into it. It turned out to be a lot easier than it thought to get started, though I did have to rebuild smbclient to have a longer timeout to get it successfully complete a full backup of a given partition. I then learned some other stuff and fine tuned the configs.... One big change was I broke out the windows hosts into individual partitions (ie, gumby_c, gumby_e, gumby_f), and came up with a 'semaphore' solution so that it wouldn't backup more than one partition at a time from a windows host. Eventually, I had all my systems in it (it fully backs up everything except itself, where it backs up only key parts....) I even got it backing up my work Mac Book Pro.

I later grew the filesystem out to 2TB.

Good-bye Gumby, Hello new Gumby

So, I decided yesterday...in the midst of a tornado watch, etc. that it was time to pull the plug on the old Windows 2000 box known as 'gumby' and set up a new 'gumby' using the off-lease Lenovo Thinkcenter M55 that I got from TigerDirect when I got back from Penguicon. Odd that last year when I got back from Penguicon, I got a Lenovo Ideapad 3000 v200....the thinking then was that the 9" netbook was a little too small for my Linux laptopping needs, so I got a 12" laptop....thinking now is a 12" netbook or something, but that'll be another story. This year's thinking is that the bookpc (Pentium 3 933MHz i815 512MB), running Windows 2000 Professional, was getting to be too slow for my needs, and maybe I would get one of those Windows XP Pro boxes from Tigerdirect, and actually run it.

The previous two IBM Thinkcentres I got from Tigerdirect got turned into Linux servers....

The odd thing of course, is that this new computer is somewhat more powerful that my main Windows desktop ('tardis' - Pentium 4 3.2GHz w/2GB)....as it is a Pentium D 3.4GHz w/2GB. (And, there are already plans to up to 4GB of memory....plan to upgrade 'orac' to its max of 8GB from its current 6GB...and the 2GB displaced is compatible here.)

After taking the old gumby apart and moving it aside, I put the new system in place...adding a firewire card (an adaptec one left over from my early iPod days) and a USB to PS/2 serial adapter to use it with my existing 4 port KVM. I left the two firewire drives from the old gumby detached for now.

I then setup and activated the Windows XP and started working it back into my home network....then added the external drives back. I then started working on tweaking it to my preferences and installing common apps like firefox.

During this I did a restore of old files from backuppc, and that went great....so I queued up a pile more. And, then installed the ever important BOINC...and set into the long process of reconnecting to various projects.

I then continued to install various common apps, along with a few extras that I think could be useful for what I do on the machine...and even better now that it is faster and has more memory. Two things that I used to do that got left behind were WiRNS and DVArchive....but I got Poopli Updater working again. Had stopped using WiRNS a few days earlier with my remaining ReplayTVs....

Suddenly it was 10:30pm....

I poked around a bit more then next morning and a little bit more remotely....so much nicer now that the machine has more memory and processing power.

Even though I'm going to reestablish getting it backed up in backuppc, I decided that I want to still have local disk-to-disk backup using Retrospect or something to an external drive. The original Maxtor OneTouch II drive that I used to use for this had died, and redeploy of an old internal drive had also gone away....but I had used Retrospect's restore to recover from bare metal before, and that's something backuppc doesn't do.

The question was how I do get Retrospect back on to this machine? I considered quickly buying a new external drive (wasn't today's shellshocker....wait I'm boycotting buying harddrives that way aren't I?) and I just couldn't get myself to pull the trigger on one at the KSU Union Computer Store....perhaps next week....

While I was looking around...I noticed that the Retrospect had stopped running on my other Windows computer (tardis)....in fact it had last run on May 13th, 2009. !!! I poked around trying to find out why it wasn't working...but gave up.... Since I got home I got it running manually, guess I'll make a note to check later to see if it runs automatically again.

Probably time to update the restore cd.

Meanwhile, don't feel that in a hurry to get that last step for 'gumby' in place. Though upgrading and replacing harddrives is certainly something I will eventually want to do.

Running Acronis MigrateEasy might be interesting. This is the tool I got when I wanted to upgrade the 80GB drive in 'gumby' to something bigger. First it was to a 250GB, but then I found that the BIOS in the machine wouldn't handle larger than 137GB....so I then used it to go to a 120GB drive. Now the new 'gumby' has a 160GB drive....and I'm sure I'm going to want to upgrade eventually. I reinstalled the program, but one of the things the install wizard complained about is no floppy drive....ya...first desktop I've purchased that didn't have a floppy drive, hmm...

May have to look at upgrading the MigrateEasy or something. Though I think replacing the current external drives will be first on the list....since I already lost one of the 3 a while back.

Think tomorrow or later tonight, I'll add 'gumby' back into backuppc.

box now has 2GB

A couple of days ago, I got a second stick of 1GB PC3200 DDR memory...and last night I finally got around to upgrading 'box' to 2GB. I had previously throwing a 1GB stick into a geeks.com order to bring 'box' to 1.5GB.

Nothing special of note happened with either upgrade. Just that I now have the maximum for this system, and it should allow it to better run BOINC work.

Though the current RNA World work assignments are calling for memory that I only have one machine that has at least that much memory....but it has 4 cores, so it can't run more than one RNA World at a time...and if I mix in other work with RNA World....the RNA World jobs always miss their deadline, because the estimation perpetually wrong.

Anyways....after I had done this...it occurred to me that I had done something odd....my main desktop (known as 'tardis') is suffering with low memory (firefox keeps consuming more and more memory...sometimes its consuming over 800MB....not to mention all my CPU....and then I made that mistake of upgrading to Thunderbird 3....plus Tweetdeck is pretty big too) Why am I not upgrading the memory in there....it has 4 slots, currently filled with 512MB PC3200 DDR memory. And, I should be able to change two of the slots for 1GB PC3200 DDR memory and everything should work. Could do 4GB, but don't think it'll see it all.

Though that computer was pretty temperamental on what kind of PC3200 memory it got....though when I do get around to finally replacing that computer, the 1GB sticks would probably go well in to 'box'....had I thought about this process better :lalala:

Wonder if there'll be hardware upgrades to my main desktop between now and when I finally get around to replacing it. Think the machine turns 7 soon.

I got another scanner -- Fujitsu ScanSnap S300

In a somewhat planned and somewhat impulse move, I have acquired another scanner. A Fujitsu ScanSnap S300. Noting that I've mentioned that I already own a ScanSnap S300M, it may seem odd...though its more of an annoyance. That I need to buy the same scanner again to use it on Windows.

But, it's a new year and I'm starting to accumulate receipts of stuff I'm going to want to submit for FSA reimbursement.... Had found out last year that I can submit receipts and stuff by scanning and emailing, instead of fax. Since I no longer have a working fax machine, and I'm not sure my VoIP will handle fax. Bringing home my work MacBookPro to do scanning was kind of a hassle, but the FSA money didn't last very long.

This year I've put a bit more into FSA, so there'll probably be more scanning to get the reimbursements. So, I needed to see about having a scanner on my main computer. And, the more I thought of it...the more another scanner like the ScanSnap S300M made the most sense to me.

So, I started watching a few different online sites to see which one had the best deal on the S300. When in an unrelated activity, I found that the price had dropped on Amazon.com....since the other sites hadn't dropped to match, and then noticing that it would possible to get it at home today by Amazon Prime. I went and purchased it.

Now I have to go reboot the computer to complete the installation of the software, before I can test that it works....

Converted box to use RAID1

Link: http://wiki.archlinux.org/index.php/Convert_a_single_drive_system_to_RAID

box is such an important server to my home network, while the last time it failed wasn't due to drive failure...there had been times in its past where it was.

And, since I was playing around with RAID a lot on orac, I decided that it was probably time that I convert box to do RAID.

It doesn't need a lot of storage....it has always been a 40GB harddrive of some sort. That had come either as stock in the off-lease system I built it around or from a ReplayTV. The latest incarnation of 'box', a Thinkcentre S51, used SATA drives, so spare drives wasn't something I had a pile of for it.

Now being a Thinkcentre S51, there wasn't much in the way of internal options of doing RAID, but there was a second SATA port on the motherboard. And, it did have USB ports...so at first I was looking at creating RAID using an external harddrive. Either USB or SATA. Leaning towards SATA (had purchased a SATA bracket).

But, I was looking for a pair of small SATA drives....at first one the same size as the current, but then a pair of small/same would do....and more procrastination.

But, then the K-State Student Union computer store had a clearance table out...and on it where various sizes of 2.5" SATA drives. And, I recalled seeing an adapter that would allow me to mount a pair of 2.5" SATA drives in a 3.5" drive bay. There was even a version that had on board RAID (and could do USB)....similar to one of the RAID enclosures connected to orac. Though I wanted to go with mdadm managing my raid in software, since it was a little bit better known to me in its setup, management and recovery. The latter is kind of important, since at work we've had fun in trying to recover systems using hardware RAID after a card/board swap or having it tell us its status by some mean other than wondering if a light shouldn't be on or something while passing by it in the data center.

But, the table had come out before I was going on my winter holidays...so I wasn't in a position to figure things out and buy it. Later when I came back from holidays, I saw that some of the 2.5" drives were still available...and had been marked down even further. The big ones were gone, and a co-worker mentioned that he had gotten a pair of 250G for just such a use. There was a single 80G and 3 120G left. So, either I could get a single enclosure and go with the old external mount of drive plan....or get a pair of 120G drives and explore the 2x2.5 to 3.5 bay adapter route. I ended up buying all 3 of the 120G drives, figuring that I'd have a cold spare for down the road.

I then checked eBay for the adapter....and bought the one that wasn't RAID or anything. I chose a seller that shipped USPS, and it just made it in on New Year's Eve.

During the thinking and research phase, I found the linked to details on how to do what I wanted.... And, I pretty much used it (with minor adjustments to suit my needs, like the differences of my ubuntu release, or that I was going to swtich to having /home on /dev/md1. Or that I wasn't going to reuse the old drive in the conversion, etc.

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
