Zen is back, with a little help from Acronis True Image Home 2011

.... kind of, though more not.

Three weeks ago today, Zen locked up. And, when it came back...it wasn't all there. It was bad....stuff wouldn't run, missing or corrupt system dlls, etc. Well, I did buy Acronis True Image Home 2011 the weekend before, and I had got nonstop backups going for a few days...and it seemed to show that it had replaced the old backup settings (image back only). And, trying to go into "Backup and Restore" launched Acronis True Image Home....

Guess I will restore the system to a previous time earlier that day. Seems the last time was about 6 hours back (and there were other weird gaps) later I read that non-stop isn't really non-stop...it'll pause if the machine is 'too busy'. Problem is it thinks BOINC is the machine being 'too busy'....didn't figure this out until later.

But, I went for it. After doing the restore, it rebooted...and...poof, I have nothing. Well, it went into HP's recovery partition instead. And, the only option enabled there is to restore the system to factory. After some cursing, I figured I'd go ahead, reinstall Acronis True Image Home and try again with an earlier time. While, that was happening, I had gotten onto another computer to do some surfing to see if there was some alternative way to invoke the restore, having not used the create restore cd option yet.

I found that I could download an iso from acronis, that was the same as what the software would've created and boot with that. So, instead of completing the initial setup screens of the freshing restored to factory...I booted from that. And, then tried looking for an earlier restore time.

Well, that interface is pretty bad. The worst part is that it sorts non-stop backup times alphabetically....so 1:59 is followed by 10:00, and then 11 and 12, before 2:00 shows....and AM & PM, those are at the end of the string...so PM times are interleaved into the AM times. Well, I remembered what time I had restored to previously, so I had a starting time to search for and try to guess backwards to a suitable restore time. There was a huge gap, now it was a busy 'vacation' day. I had a doctor appoint in the morning and then an MRI in the afternoon. The first restore attempt had been to a time shortly after returning from the MRI. The next backup times were for a period after I had returned from the doctor appointment. Might be okay....I would probably lose one Quicken transaction, but I could easily put that back (entering that I had paid co-pay)...I had read emails then as well as after the MRI, but I didn't recall anything too important that I had to get back having come in since my morning email check.

So, off it went....oh the first restore attempt took hours and I had gone to bed hoping to find Zen back in the morning. Now the next day, I was running a bit late for work...but I got it going, with it reformatting and updating partition settings first and I hoped to come home from work and be up and running again.

Well, that's not what I found. I was back at the HP Recovery Partition screen. So, I rebooted from the Acronis recovery disk, and this time I hit the search for backups option to see if it might find anything else. I figured it was worth a shot, while I mulled over the idea of starting over from scratch....at least I had the stuff in backuppc (sort of). Well, it did find something else...it found some image backups...odd. I had played around the option in Acronis True Image Home, but thought I had opted to go with non-stop backups and a fresh start with the external drive.

But, it seemed to be valid images and it was from the night before the crash. So, I used that to restore. I only made one mistake, where I marked the C: drive as active instead of the hidden system partition. Booting a GParted Live CD, I switched things back and that got me going again. Now while I was in the GParted Live CD, I noticed that it saw two internal drives...instead of the Intel Matrix RaidVol. I suppose that means the Intel ICH8R Matrix Raid is actually another FakeRAID, and after some searching around I found it to be true.

Hmmm, wonder if I shouldn't have bothered ordering the system as RAID1 then? Years ago, I had built a PC using FakeRAID...and it was kind of a mess after the motherboard failed (around the time where lots of motherboard makers were having trouble with counterfeit capacitors.) Yet, I'm considering building a machine from scratch again.... :hmm:

Wonder if it being FakeRAID is why after crashes it messes up the RAID, and has to initialize again (was scary seeing that the first time)...and then verify and fix errors.... wonder if this is going to happen every time Windows 7 fails to shutdown safely?

Oh well, try the boot....and success its all working again. I then look at the backup drive to see what I had restored from. Well, before I setup Acronis True Image Home 2011, I had been using Microsoft's image backup option, and scheduled it to run every Tuesday night. And, it usually runs on through to Wednesday night. Though it did seem to not take as much time lately....guess Zen also getting hit by backuppc at night was slowing the image backup down. I had looked at blocking out that night in backuppc, And, at this particular time...there was no hit from backuppc, because I had taken I was in the process of building a new array (I plan to write about that later) I was between backups.

Guess I'll leave Microsoft's image backup going...since it worked. Though it has one annoying negative. It removes the previous backup before creating the new backup, and if something goes wrong...no backups.

Meanwhile, I couldn't get non-stop backup to go again...probably a mismatch in state or something?

I then dig through the non-stop backup and restore a few files that had changed since the image backup.

Worked on Orac last night

Back on March 28th, when I last wrote about working on Orac, I mentioned that I looked at the harddrive cage to see about the condition of the fan on there....only to find that there was no fan there.

Reviewing the manual on the Gateway website, I found that the cage is used in more than one model...and that some of those models have fans, while evidently mine did not. Browsing the parts list for some of the other Gateway models that used the same drive cage, I found reference to a 60mm x 10mm fan, which I deduced was probably the fan that I would need to get for this location. I did find that from the Gateway manual for my model, that the motherboard did have a front chassis fan connector.

So, after some thought and checking first amazon.com, it struck me that eBay might be the better place to go. So I found a seller on eBay that explicitly said he shipped by USPS and bought one, and from another seller I got fan screws (a bunch of them, because I've needed them in the past before and I'm sure I'll have need for them in the future....as it was I didn't actually need them this time though.)

Because I had recently built my new backuppc pool (should be posting about that adventure some day), I had been waiting for a moment when Orac was idle again and not busy refilling the pool with full backups of everything....It hadn't gotten any fulls of Zen yet, it didn't detect that Zen had gone away to apply the recent Microsoft patches during its recent attempt, so I had to step in and stop it. So that seemed like a good time to take Orac down.

Worked on Orac yesterday

Yesterday, I decided that I should poke around Orac in preparation for building that new 5x2TB RAID5 array. My backuppc pool keeps filling up, and deleting old backups isn't freeing up enough space anymore (5x1.5TB RAID6 array.)

At first it was just going to be a simple procedure to add two eSata cables from the computer to the Sans Digital MS2T+B, and then shutdown and move the two 1TB drives in RAID 1 from the bottoms slots of my TR5M-B (upper 3 are unoccupied). But, as I was pushing on the cables the bracket popped in...so I had to open the case to put it back in place.

While I was in, I decided to see what kind of fan is on the drive cage. A couple of weeks earlier, I had gotten a SMART alert of high temperature and cacti showed that there was a rise for a few hours in the late evening. It had been warm that day, warm enough that I touched the AC briefly in the earlier part of the evening. Guess I needed it to stay on the rest of the evening.... But, there was no fan...though there were mount holes for a fan, and there's supposed to be a fan connector on the motherboard for it. Though not all models had one, so evidently not the GT5635E. Though wonder if I should, maybe the addition of the second internal drive makes it desirable (so far I've had to replace the second drive twice....the current one is now a newer generation than the original drives, and runs cooler.)

Since there wasn't a fan, I didn't take the cage out....so I didn't measure what size fan might go in the spot. Though I have a rough guess as what size it is, so perhaps later on I'll pick up a fan to put there. I should probably see about a new rear fan....perhaps a faster one might help.

But, I put things back together and moved the drives, started things back up.

Of course, the first problem is now all my drive letters are different....which messed things up like cacti (hddtemp recording), gkrellm and rc.local (where I changed the i/o schedule for the RAID6 array drives to noop). There was also the complication that the filesystem on the drives I just moved hadn't been fsck'd in over 6 months. So, it needed to fsck them. root also needed be fsck'd. It took a long time to boot, but eventually did. Though the filesystem on the moved RAID1 array hadn't finished checking...had set 'nobootwait' on filesystem. I'll probably remove those now...since they have fixed Bug #563916. But, after fixing rc.local (and before fixing cacti) I rebooted....so it still needed to do the fsck.

Later I still had to reboot again, because two services that reference the filesystem....weren't happy...well, one was really unhappy and the other wasn't reporting valid information for it and needed a restart to make it work (I couldn't probably have fixed the issue without a reboot, but I wanted to make sure it rebooted right after another change I had made. There's still something odd going on, affecting a different RAID1 array....will look into that later (or I could opt to move the filesystem to the RAID6 array)....since it could use a grow.

I moved orac today

Its time that the full backups have been taking place on orac's backuppc. And, my /var/lib/backuppc doesn't quite have enough free space for a full of some of the jobs (I guess it doesn't matter if many, if not all, of the files would already be in the pool, it still needs more free space than I have in the filesystem to do the job).

So, I was looking at what I could about moving some stuff around so that I can grow /var/lib/backuppc by more some more....to perhaps 3.5TB. And, I thought about why it was that orac was located where it was. Basically it was just an open spot near the monitor.... And, it really needed to move somewhere, where I could better park the external drive cases. Currently the main one was a Rosewill RSV-S5...there's a Sans Digital TR2UT-B, but I had recently picked up a Sans Digital TR5M-B that I needs a place where I can park it near orac.... Along with the two old 500GB My DVR Expanders.

So, the plan was to move it next to lhaven, though I ended up moving lhaven into the spot opened up by orac. orac has side vents so it couldn't go exactly where lhaven was, but decided to move lhaven out of the way so that I could get in and cable up orac.

Before turning orac back on...I did the storage changes. I setup the Sans Digital TR5M-B, its smaller than the Rosewill RSV-S5....moved the 2 1TB drives from the Sans Digital TR2UT-B over to it, and hooked up the 2 old 500G MyDVR Expanders to the regular eSATA ports on the back of orac (the system has 6 SATA ports internally, and I had gotten 4 port SATA back to run 4 of the ports out for future upgrades....that was before I got the 2 port PM eSATA adapter for the PCIe x1 slot.)

Also discovered that the bays number the other way around in the TR5M.

Now with orac up again, I was kind of expecting the drives to be in different places...but they were all in the same place. And, 500G MyDVR Expanders in sequence after the two internal drives.

Quick look around, and then immediately went about turning the MyDVR Expanders into a RAID 1 set and a single ext4 filesystem. And, then I started moving files over to it. Of course, that slows down the build of the RAID....

But, now to wait until I decide how to move the other pieces around....

Wonder how long before I amass the 5 2TB drives to build the new RAID5 to move the current /var/lib/backuppc over to.... (keeping the current 5 1.5TB RAID6 for more important data).

Sleep Diary Spreadsheet

With an impending PSG/MSLT (December 2nd, 2010), and a particularly disrupted night's sleep recently...I got to thinking that I would start my sleep diary now. Rather than wait until the requested 2 weeks before the PSG/MSLT.

Of course, the sleep lab provided a sleep diary on a printed sheet to fill out. Which means either I fill it from memory now and then, or carry it wherever I go. If only there were some way to, say, use a computer.... :hmm:

I did a quick google search, and all I could find were PDF files. Surely somebody else has thought of this? :?:

So, looking at the provided sleep diary sheet from the sleep lab, I sat down and created a sleep diary spreadsheet using OpenOffice....using my laptop (Ubuntu 10.04LTS) [which when at home is on futon in front of TV, but I'll be at Chicago TARDIS the weekend before the PSG/MSLT]

:!: SleepDiary.ods :!: BlankSleepDiary.ods :!:

I opted to leave it in the default format, so that I won't have to deal with OpenOffice asking if I'm sure that I want to not use OpenDocument format.

I then saved the file into my Dropbox folder and created a link from my desktop to it. I can now update my sleep diary wherever I might be.

Such as living room computer (Windows XP Professional - OpenOffice), or computer next to bedroom (Ubuntu 10.04LTS 64-bit Server), or computer at work (Windows 7 Professional - LibreOffice).

Liking the result so much, I've decided that I should share it. &#59;D

ddclient & squid

In the aftermath of the summer storm of August 13th, (hmmm, totally missed that it was a Friday the 13th), I made a tweak to my ddclient config for updating dyndns for my DSL line. Because I found that it wasn't able to update the IP change while Cox was down.

Couldn't find a way to make ddclient to bind to the local IP that routes out by DSL (or use non-default gateway). But, since I have squid proxy on the same box...and depending on what port I come in on, it can use either of my connections.

I set proxy=box.lhaven.homeip.net:3128

Couldn't use localhost, because ddclient does some kind of validation to require an fqdn+port, and localhost isn't an fqdn. And, yes, I use my dyndns domain as my home domain. So I can have bookmarks that'll work whether I'm at home or on the road &#59;D

But, this change wasn't tested...as it has been less than 28 days for a refresh, and no IP change.

That was until this morning, when my IP did change.

The updates weren't working....seems that ddclient wants to do SSL all the way or not at all. No using an http proxy to connect out on SSL. But, I didn't feel like sending my dyndns password out non-SSL.... So, after some thought, I decided I would figure out how to set up SSL on squid.

I made the necessary configuration change, but no go. Seems that ubuntu doesn't distribute squid with SSL, because squid and openssl have incompatible open source licenses. So, I did a quick search to find the ubuntu way of rebuilding it from source.

apt-get source squid
apt-get build-dep squid
apt-get install devscripts build-essential fakeroot
cd squid-2.7.STABLE7
vi debian/rules
     Add --enable-ssl \ to “# Configure the package” section
debuild -us -uc -b
cd ..
dpkg -i squid??? squid-common???

Change to proxy=box.lhaven.homeip.net:3218, and it worked. :cool:

orac's RAID6 is back

Last Saturday, I woke to find lots of SMART dialogs on orac's screen. It wasn't happy about a lot of drives, I had expected to see one or two...the usual when it does its monthly mdadm checkarray....except it wasn't Sunday yet.

I then saw that lots of drives were reading in the 80's Celsius. Concluded that the fan in the array had died and shut things down.

I then opened to see what kind of fan it used and see what my options on replacement were. First I tried looking for the exact part no. ARX DC Brushless FD1212-S3133E, DC 12V 0.32A. Lots of results of people complaining about it, etc. Not much in the way of satisfactory places for me to order it. Plus wasn't clear that it was sold in the specific pin configuration that the enclosure was using. It has a 3 pin on it, plus a 2 pin that doesn't quite look standard. Its the 2pin that plugs into the backplane of the array.

I then started looking at 120mm x 25mm 12VDC fans of comparable specs....figured I'd sort out the connector problem when I got it. I know I have a new soldering iron somewhere...that needs to get unsealed and used. &#59;D I then decided that I would take my search to Amazon.com and wait for it to lineup with getting it Wednesday... I ended up going with a Cooler Master Excalibur 120mm PWM Case Fan - Barometric Ball Bearing R4-EXBB-20PK-R0, it was more powerful than the old fan...but it came with 3pin and molex adapters. And, there's a pair of those feeding the backplane inside the array, so I figured on just tapping one of those to run the new fan.

As a side possibility, I would plan on checking the University computer store to see what they had on hand... I never got around to making that trip, but that's explained in part further on....

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?

'Accidentally' Upgraded 'box' to Lucid

Last night I wasn't thinking....running into the fact that my boinc-client package is broken on 'box', I thought..."why isn't it running the boinc-client from Lucid?" And, I proceeded to fix it with "apt-get"...and then realized that I'm still running karmic and unbreaking it wasn't. The boinc-client pre-Lucid is too old for a project I'm in, and it is annoying how ubuntu doesn't update packages within releases (which get's really annoying with LTS.)

Anyways....I decided the way to resolve the mess I had now made by downgrading my boinc-client, was to upgrade to Lucid Lynx 10.04LTS. It was my plan to upgrade both my Ubuntu servers to 10.04LTS (the other being 'orac' which is currently 8.04LTS)....but I was going to put it off to when I had more time and allow time for the release to stabilize (given all the issues I had when I first started running box on fresh Karmic).

So, it started....things got a little annoying, in that the upgrade requires attention....and I didn't want to spend my whole evening watching it upgrade. So, I'd check it now and then, and sometimes find it stuck waiting for me to make a decision for it, though the first one where it wants to restart stuff after a pam upgrade...that's annoying. Just do it okay, stuff it restarted weren't working right along the way anyways. Namely I found that I couldn't access websites...at first I thought the squid had become dorked, and I couldn't restart it because invoking /etc/init.d/squid said it was now a service...but using service didn't find it. Though later I realized it wasn't working because DNS was broke ('box' is my primary DNS server)... I was able to restart that in the usual manner.

Partly because of the pauses, and a bit due to slow download....it wasn't looking like I would finish before 'bedtime'....but it seemed that it would be close enough.... It wasn't, but I ended up staying up to the bitter end. So, that I could reboot and do a quick check that all was clean.

Namely, I checked that named, dhcpd, ntpd and squid were running (since these were some key services of this server, and were ones that often failed to start after boot in karmic...especially named. Manual start always worked...at one time I was restarting these services in rc.local where it always worked rather than at the 'normal' time).

Then I went to fill in the missing icons in my launcher panel....there were two holes, there also seemed to be a hole in the tray area. The missing icons were Evolution (which I right-clicked to make reappear), and boxee (which I installed the latest of). I then called it a night.

The next morning, I continued to poke around some more....adjust appearance, add some chat/broadcast accounts...and look into my ubuntuone issue....first the tray thing was missing, apparently its by design...but, I don't remember that. I poked around some more and some more....then I looked at 'ulkc' and saw that it also didn't have the tray applet anymore, and I just didn't miss it... So, I then went to check that it was connected to my account and sync'd. Actually, it really was syncing, etc. When I was at Penguicon, I had put a copy of the pictures I had taken into my cloud...expecting to see them later on 'box' when I got home. But, it would never appear. Upgrading 'ulkc' didn't help things.

During the poking around, I disconnected 'box' and reconnected...and that apparently fixed whatever was wrong, as it started syncing...and soon the folders appeared.

While this was going on, I thought that maybe I would need to finish things up by remote....so sadly I discovered that remote desktop still doesn't work in Lucid. Turning it on, consumes 50% of my CPU. My 8.04LTS (orac) doesn't suffer from this problem. But, I want to bring both servers in sync eventually, so I can see about getting failover for dhcp working between the two.

Oh well....at least it seems more successful than when I had upgraded 'box' to Karmic. And, now I'm at an LTS where it can stay for the next 2 years.... We'll see what happens when I upgrade from 8.04LTS to 10.04LTS next month....

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.
