zen resurrection

This was originally going to be a very long post, but I kept putting this off ... and now I just feel that something needs to be said.

The story starts with waking up on February 15th, to find zen was dead. It had self updated overnight, and now it was unbootable, and the start repair couldn't get me back. Apparently, the problem had started long ago with all the previous times where Windows 7 would lock up...usually under intense disk activity...and the afterwards, the intel matrix raid would require re-initialization of my 1.5TB RAID 1 array.

Apparently, it was slowly corrupting my drive....because trying to restore from WindowsImageBackup was also a failure. Since this happened the day before Gallifrey One, I had to wait until I got back to do some more serious attempts to recovery, during which I ordered a full copy of Windows 7 Professional, hoping that a repair install might be an option. It isn't because the repair option can only be invoked inside a running Windows 7 system .... in need of repair. Not by booting the disk. ARGH! :##

At least I should have the data in BackupPC to restore from.....though hopefully before the bit rot of its ext4 filesystem makes it go away. Plus I had hoped to get some configuration going where I could mount the RR62x RAID 5 array, and get at the Oops!Backup store.

So, the plan now was to wait until Ubuntu 12.04LTS to land and then maybe some configuration of running Windows 7 in VirtualBox and recovering into that, etc.

Orac is looking strangely bare, with Zen taking over.

For a long time, I've been running a 6 drive RAID 10 array of Hitachi 5K3000 2TB drives in Orac for backuppc. This configuration got me at 5.4TB array, and somewhat better performance than when I tried a RAID6 configuration. But, eventually, I kept running out of space and the price of harddrives went up so expanding the array over time didn't happen as I had hoped. Being RAID10, the options were other concat another array, either 2 in RAID1 or 4 in RAID10 or 4 as 2 RAID1....using volume manager. Or maybe see if RAID10 would deal with having all 6 drives upgraded to 3TB, though hadn't considered the transition of 512 to 4k and how it would cope with that.

Though I did, eventually find out when I upgraded a 1.5TB RAID1 set to become a 2TB RAID1 set....going from ST31500341AS to ST2000DL003, where I contributed my experience here: http://askubuntu.com/questions/141669/creating-properly-aligned-partitions-on-a-replacement-disk/ Though it first started because one of the ST31500341AS drives had failed.

Before the failure of one of the 1.5TB drives in the above mentioned RAID1 set, I had 4 ST31500341AS in a RAID5 on old-Zen. It had been done in under RR622, under Windows, and NTFS partitions, etc. I had tried copying the data at various times, not really having anywhere that would hold the data elsewhere...but wanting to get it over to FreeBSD for recovery. While I got the rr622 driver working, and it saw that I had a single array (rather than the native driver that would see the 4 individual disks.) I couldn't get access to the data. Though it had worked when I was previously playing around with Xen (had tried copying it then....to a 2 1TB RAID0 set, but then one of the 1TB drives died....so I lost the copy, I had then replaced it with a 2TB RAID1 set....using an ST2000DL003 and an ST2000DM003, the DL being a 5900RPM drive and having a 5 year warranty...while the DM drive is a 7200RPM drive, but with only a 1 year warranty. And, turns out the 1 year is generous.

At work, I had built my FreeBSD desktop using a pair of the ST1000DM003 drives...and 3 drive failures later....it is now a pair of ST2000DL003 drives. Yeah...I was having trouble with the array, and apparently using XFS was a mistake too...because I thought it was recovering, but instead it was slowly eating the data. When I had nuked the RR622 RAID5 array, and had switched to using it as JBOD and create a RAIDZ set under FreeBSD...I found that there was nothing to copy back from the RAID1 array. D'Oh! >:XX

Though I had also copied the Microsoft WindowsImageBackup files, to see if I could mount the VHD file under VirtualBox to help in recovery. I largely had the data in bits and pieces elsewhere, it was the environment I was wanting to recreate...and Oops!Backup didn't back up that part anyways (the data I was mainly trying to migrate). The image mounted, and I could see it...but soon after Windows would try to fix it and then it would disappear....kind of like what it did on February 15th to make the original Zen go away. No idea what kind of disk rotting the Intel Matrix RAID had been doing, when it had to initialize the array again every time after a Windows crash. I've had Ubuntu crashes, but the RAID arrays remained stable...usually. While Windows & Intel RST....it was pretty much every time. I'm sure it was slowly corrupting things overtime to where things wouldn't recover, though it choose to do that after an automatic reboot for Windows updates...and the day before I left for my first Gallifrey One made things even more annoying.

Anyway with another 1.5TB drive freed up, I contemplated adding it to the RAIDZ I had made of the 4 1.5TB drives, keeping it as a hot spare, or just use it by itself -- living dangerously. I ended up with the latter for some temporary data. Because in my mind I was starting to lean to what happened next.

ulkc has 8GB of memory

So, a while back I read that it would be possible to upgrade a number of older computers from spec'd maximum to a bit more.

Officially, the maximum supported memory of the Lenovo 3000 V200 (ulkc) is 4GB... My other laptop also supports a maximum of 4GB, but I suspect that between them, I should be able to upgrade one or both to 8GB. Though I prefer to have it work in this one, since I use this one more.

So, a while back I had a newegg coupon to get laptop memory, so I got a pair of the SO-DIMMs. But, then I set them aside....and forgot about them.

More recently, I picked up a new battery for this laptop...and had it in the bedroom to run down and see how much life I would get. Online they sell aftermarket batteries for 4800mAH and 5200mAH. Though it turns out the original battery was 5200mAH.... So, that's what I have....anyways it works. And, I let the laptop rundown. So, I was going to try the memory swap after that. Though that was a few days ago....

lhaven misstep - nForce4 blows OCZ

So, lhaven was this computer I bought specifically for Stanford's Quake Catcher Network project. This was because when I received my sensor, I found that it only worked on Windows or Mac. Linux would require the older sensor, which they weren't selling anymore.

Things seemed to work...except that the machine would lock up now and then. Well, it is Windows...so maybe I'll just schedule it to reboot regularly.

At first that seemed to help...but gradually, I was rebooting it more and more frequently. Eventually, I was down to rebooting it 5 times a week. Sometimes it would fail to restart, other times it would still lock up between reboots.

Eventually, they came out with Linux support for the sensor and I moved the sensor over to orac. That worked great for a while...and then it got a kernel update, and then starting VirtualBox would cause the machine to reboot. And, not just when I needed up update my Quicken. Because I was also participating in LHC's Test4Theory.

So, it was time to find a new home for the sensor. After moving it back to lhaven.

I looked for various low power x86 dedicated SBC or plug computer to run it. Though these things aren't cheap, so I'd want to do more than just QCN with it.

Then it occurred me...that I was overthinking this whole mess. Why don't I just install Linux on lhaven?

I haven't been looking forward to the leap from 10.04LTS to 12.04LTS. While Orac has a GT440 in it that's not being used, not sure what I would do for box....though I've been eye'ng either a GT218 or an NVS 300. It only has an LP PCIe x1 slot.... there are other concerns.

In the Scheme of things...I had planned to upgrade the video card in zen someday...and take its GT420 and change to an LP bracket and put it in lhaven. Hadn't quite worked out what I'll do about gumby, but it has since died...and when I get around to resurrecting it, I might have a Radeon HD5450 that I'll free up (not sure if it helps with BOINC, but eventually...I want all the systems using DVI....so I can switch to my new 4-port DVI KVM. DVI to VGA through the old KVM was horrible....plus keyboard issues with the old KVM, makes me wonder if I can wait until I can fully make the switch.)

So, I had downloaded 12.04LTS beta1, but never got around to install it anywhere....and when this idea occurred, 12.04LTS beta2 was just starting to appear. Though the question was, would I go with ubuntu, or try one of the other variants. Namely, xubuntu or lubuntu.

I ended up going with xubuntu 12.04LTS beta 2. I didn't hear about lubuntu until after I had started downloading xubuntu...so I envisioned that I would resurrect gumby with lubuntu....though so far I haven't gotten around to that.

I got a Brother DCP-7065DN

In a rather impulsive move, I bought a Brother DCP7065DN Monochrome Laser Multi-Function Copier via an Amazon Lightning Deal!

I had been considering getting a new laser printer for a very long time. I had ditched my old Brother HL-630 laser printer about a dozen years ago. This was a crappy printer from the start...with its grey background problem that they never seemed to resolve. Had gotten it from Future Shop of years way gone by....where it had been a special buy for them...so they were selling them really cheap. Kind of like the Canon BJ-5e bubble jet printer I had gotten before.... (It was a BJ-10e, but made cheaper just for them. And, used a special ink cartridge not used by any other model from Canon...at the time. Otherwise, I often wish I still had it....though when I moved from Canada to the US, it became kind of a problem to get ink for.)

So, after the Brother HL-630 was scrapped....I spent a long time thinking about my next laser printer....I was heavily leaning towards getting an HP Laser printer....so it was going to likely take a very long time before I would make a move. And, then I started to lean towards getting a Color Laser Printer.....and then I wanted built-in Duplex. And, having been spoiled by the HP Photosmart 8450xi, it also needed network capability....

There was an HP Color Laser printer that seemed to fit the bill, and it was popping up on sale now and then. But, then I upgraded to Windows 7...and found that not only is my old Photosmart 8450xi no longer fully supported in Windows 7, neither is the HP Color Laser printer that I had been considering.

So, that nixed wanting to jump on it the next time it went on sale. (Sale as in cheaper than it would cost to buy 4 new toner cartridges for it.)

So, the search continued....I started looking at Brother again....in current models, something like the HL-4150CDN or the HL-4570CDWT.... but, then I was introduced to a multifunction printer. Which actually was kind of useful. Being able to scan a document onto a USB drive. And, there's always the once a year or so occasion, where somebody wants me to fax something. I used to have a fax machine...first a dedicated thermal fax type thing, and later a refurbished HP OfficeJet v40xi. A power surge took out my first fax machine...and then a few years later...living in the same apartment still....a power surge took out the HP OfficeJet....

So, I then started to consider printers like the Brother MFC-9560CDW....plus the idea of color copying seemed useful, especially duplex color copying.

Of course, now its getting expensive to start and expensive to keep....

I also had this issue of printing envelopes....a capability I had lost when I upgraded to Windows 7. The Dymo Labelwriter that I had gotten from stamps.com didn't work on Windows 7. And, I didn't really want to buy a new Dymo Labelwriter to keep this capability. Eventually I canceled stamps.com, though still have the occasional postage need....which it would be nice if I could still print postage, etc. Think there are cheaper ways than stamps.com, but probably not from Linux.

But, then last December while visiting my parents...my dad snapped up a Brother HL-2270DW, and this was a pretty decent little printer. It was on sale for the holidays...but it does PCL emulation. I wish I had just gotten one of these for myself then, too.

Instead, I started to reconsider whether I really needed color laser. Around year end...there were things I needed scanned or copied, for things like taxes and FSA...so I was still was still leaning towards getting a multifunction printer of some sort. And, I kind of fell for the Samsung SCX-47xxFN, and then later the Samsung SCX-4828FN (about $400). The 4828FN adding Postscript emulation. I've always wanted a postscript printer....

Though these are still expensive printers. These ones had fax....and I did have to need to send a fax once this year, so far. If I were to leave out fax, it should've been something like the Brother DCP-8085DN (about $350)....which would've had duplex copying, and both PCL and PS emulations.

But, instead the Brother DCP-7065DN showed up as an Amazon Lightning deal for $80 (50% off)....I did a quick google search to see if it work on Linux, and some sites seemed to say it had PCL and PS as well. And, bought it.

Well...apparently its common in the industry to make similar internals/firmware across their product line with different features available or not, etc. And, Brother didn't even bother to remove PCL and PS from the capabilities page that the printer spits out or not advertise the LPD queues for these modes in its network info. But, trying to use the queues is like sending to /dev/null. This particular printer is only GDI (so in someways worse than the HL-2270DW ... currently about $120. And, then there's an HL-2280DW for about $10 more, and adds a scanner....a network scanner would be useful. Though a standalone scanner would be more useful during my situation where my primary desktop is dead.

But, I was able to get the DCP-7065DN working from my Ubuntu server, after following some websites on the subject. Namely..the detail that they only provided 32-bit deb's, and I have a 64-bit Ubuntu Server. I haven't tried the scanning feature, since the printer sits by TARDIS...and I have my Fujitsu ScanSnap S300M working on my Ubuntu server....though not sure if I've gotten the two-sided scanning part to work. So far the bills that I've needed to scan for FSA reimbursement have been one-sided.

But, the DCP-7065DN doesn't have a duplex ADF...so it doesn't provide an alternative. And, my other scanner is a Fujitsu ScanSnap S300! (I bought the Mac only S300M on a Black Friday sale, and back when I used to bring work macbook pro home now and then. Later I got the S300, when I had more FSA money to spend and wanting faster turn around...but wasn't bring the macbook pro home anymore.) A regular flatbed scanner has been on my wishlist...perhaps the DCP-7065DN will satisfy that need. Something to probably check out after I get around to finally upgrading TARDIS.

So, while it was a problem to find that the DCP-7065DN is only a GDI printer...it does currently work from Ubuntu...and sharing it out from my Ubuntu server is interesting. There's no native DCP-7065DN driver in Windows XP, but I just pick some Postscript printer driver...and that worked. And, it looks pretty good (compared to the early days of ghostscript...)

What what I'll do when I finally get around to rebuilding my Windows 7 desktop????

CPAP Data Recovered

As I may or may not have mentioned, Zen failed to boot after it got the latest set of Microsoft patches on February 15th. After various attempts to recover, it has been declared lost. I haven't gotten around to resurrecting it.

So, I've been making do with a Windows XP VirtualBox that I have my on Linux system (starting to look like when I do get around to resurrecting it, I'm going to try 12.04LTS Desktop and Windows 7 in VirtualBox....)

Previously, it was just Quicken and then TurboTax. But, I've been wondering about my CPAP data.

First was EncoreViewer. How do I recover that historical data. I knew where it kept the files, because I had copied them from TARDIS into Windows XP mode. The question now was how do I get the files out of Windows XP mode. In the end, the answer was WinImage...to merge the differencing-VHD that Windows XP Mode uses, into a single file and then convert it for VirtualBox use. Could've gone direct...except that I found first try with WinImage didn't work...so second time I converted to a fixed VMDK file, and then converted the fixed file into a dynamic sizing virtual disk for use on VirtualBox.

Though later I realized that I only want it as read-only....to get my data back....anyways.

That worked.

Next question was how do I recover my data in SmartLink.

I installed it into my Windows XP VirtualBox, and wondered where does C:\ProgramData exist in Windows XP space....but, while poking around, I remembered it has a backup/restore database option...and wondered if I had ever done a backup.

I lucked out. The last time I used the software was the only time I had ever used the backup function....and that's just perfect, I restored from that and then did my latest downloads from both my xPAPs.

:cool:

Just have to see if I remember to do another download before my next doctor appointment. I didn't print anything, because I hope that by then...I'll also have my new printer. :))

Dropbox offers up to 5GB of free space to anyone willing to go beta -- Engadget

Link: http://www.engadget.com/2012/02/03/dropbox-beta-5gb-free-space/

I was just wishing, I had a little bit more space in my dropbox....when I came across this.

This is also gives me the excuse to play around with my new camera lens. An smc Pentax DA 35mm f/2.4 AL.

Wonder if I should still take both lenses with me when I go to Gally?

It does make we wish to add an smc Pentax 70mm f/2.4 DA Limited to my setup as well…. Also wonder if there’s a Pentax K-01 in my future....

Additional note about my new lens....I added the usual filter to it, a B+W 49mm Clear UV Haze and some what unusual, a hood.... 49MM metal lens hood for Pentax.

After which, I learned that a 58mm cap fits the end of the hood nicely....so I bought a Promaster SystemPRO White Balance Lens Cap - 58mm.

But, this then means that the Camera Buckle Lens Cap Holder; for 62, 49 and 40.5mm Lens Cap Sizes that I had gotten wasn't sufficient anymore. Though it never really was, given that one side is blocked with on my strap...so I guess it really worked out that I needed to add another one of Camera Buckle Lens Cap Holder; for 67, 58 and 52mm Lens Cap Sizes to my strap as well.

62mm is the cap size of my Tamron AF 18-250mm F/3.5-6.3 lens....which is now the other lens that I'm debating if I should bring on my trip....

Meanwhile...I'm wonder where one finds a lens chamois these days.... Think I at least have a recent lenspen somewhere. Also I discovered that the online storage part of my Eye-Fi cards aren't working....probably has to do with the great password reset at DreamHost.

Orac Lives

Back on December 18th, Orac went down unexpectedly....it was shortly after I turned on the heat that morning. So, at first I thought it was a heat problem. I directed fans at it, dropped in a slot cooler, scaled back BOINC (eventually suspended it). But, Orac would suddenly stop. I watched thermal monitoring in cacti, and it CPU temps weren't hugely different than before. After a while, I had to go to work...so I left it off while I mulled options.

I tried changing the rear case cooler (when I had it open to add a slot cooler and check the other fans), I had bought a 92mm fan with the plan to replace that...but I discovered that I had bought the wrong kind. Probably could've made it work, but opted to try again. I don't recall if I ever checked if the CPU fan was okay. Last time I had cleared out a lot of dust from it....it wasn't full of dust this time, is all I recall.

After some more fiddling I started to suspect power supply, I had been thinking of getting a bigger power supply for it for a while...so I went ahead and got one, a Corsair Builder Series CX V2 500-Watt 80 Plus Certified Power Supply - CMPSU-500CXV2, along with different 92mm fan (a Zalman ZM-F2Plus 92mm Silent Fan). Mulling things some more and reading other online articles...I then added some more items to my order, like new thermal compound and a CPU cooler -- a Thermaltake TR2 M21 RX A4021 CPU Cooler for the Intel Processor 115W LGA775-Prescott -- which later turned out to be the wrong kind....need a 4 pin fan for CPU. Though wasn't convinced I needed a new cooler.... But, the stock cooler was rated for 95W, and Intel's website says my CPU does 105W.

Even though I got the new power supply on 22nd, and I took the 23rd off from work...I didn't get around to actually working on it until late on the 24th (after it was too late to get anything one-day Prim for the 27th.) It was quite an ordeal getting the power supply in...had to pop the fan off the CPU heat sink to get access to all the connectors and stuff. Put the fan back on too soon, so had to get it off a second time. This time it broke. Well, I guess I swap the cooler after all. Except then I discover that the new cooler I had gotten was the wrong kind. So, I go to Amazon to see if I can quickly get a different one. No luck there....so order one by regular 2-day Prime. I went with a Arctic Cooling Freezer 7 Pro Rev.2 - 92 mm - 130W.

Original fan and the previous one I ordered, were the kind that blow to the CPU. This one has heat pipes and blows across. Reading reviews, I saw warnings about how much taller these things are and whether it would fit...so I decided that 92mm something was probably the safe maximum to consider. After narrowing through the choices via Amazon Prime...it came down to the one I got or the Arctic Cooling Freezer 13 Cooling - 200W. Since, I had about 72 hours to place the order...I held off, to see if there was anything else I wanted to add before ordering. Mistake. Later on Christmas day, the prices on lots of things...specifically these CPU coolers went up. And, the 13 went out of stock (by Prime.) Though I had decided the 7 was the more likely choice, since I didn't know which way I should position the cooler and it had four way flexibility. Though I suppose others would have the flexibility too...its been so long since I've done this kind of thing...I don't know.

Anyways...I finished putting orac back together with its new power supply, moved the slot cooler to the bottom. Removed the old heat sink/cooler (should've kept the parts though) and cleaned off the CPU. And, set Orac aside for later work.

Getting dry in my condo, cooler too.

Winter has been weird this year...but there's a winter storm alert finally? Though its the rain and snow kind with ice accumulation and inches of snow type. Just as long as it isn't another icepocalyse of 4 years ago.

Though seems interesting that the computer I bought to replace the one I lost during the icepocalyse, died on Friday. Almost as if it was designed to die after 4 years. Annoyed, because its orac, my backuppc/file server. There's 16 drives on the machine, a total raw storage of 23TB....though only about 11.5 usable TB. And, a whole lot less in TiBs.

I'm hoping its something simple though....was looking at the hardware monitor in the BIOS screen...where it reads out voltages...and the lower voltages are low....though are those from the supply or are those generated on the motherboard? Seemed to me that motherboard generates some of the values, but not sure what I'll do if that's the case.

Also seems odd that it died shortly after I turned on heat Friday morning. Anyways...I had been considering getting a new power supply for orac for other reasons, so I jumped over to Amazon and took the plunge to get a new one by Amazon Prime. I had also been meaning to upgrade the case fan on it orac....I mentioned this before....stock fan is 80mm, but there's holes for a bigger fan. I had/have some extra ones around, so I had tried those...except that my extras are too big...so not 120mm. So, I had looked at 92mm, and I did end up with one, but failed to notice that it wasn't a 3-pin fan. So, maybe I'll add one of those to.

So, cart is adding up...and I'm looking at items I have 'saved for later'....and well, new humidifier is among there. Its pretty expensive....~$88 Its an Essick Air Tower Humidifier, though its about the same price as what my old Essick Air unit...though thinking the tower form would work better with where I've been using the old one, plus the old one's fan has become the issue... Though I guess its only 2 years old. I wish I could find something like the humidifier I had back when I was in Medicine Hat....while it eventually got nasty inside, that thing worked well for years and wasn't that expensive as I recall. And, it was easy to fill too. Since, then...I guess the Essick Air is the first one that I got more than one season out of....two whole ones, in fact (though some debate as to how well near the end.) And, it did a good job too. Plus the tower I'm looking at, uses the same wicks as the old one...so I already have an extra set somewhere.

Though having an extra set of wicks isn't a requirement for what I get...though footprint and output are...and pretty much I think wick types are the only kind I'll consider now. And, brand isn't necessarily a requirement...though past experience with other brands has made me leary of others. Plus there's feature differences. Some do take less space, but only have one tank. But, I'm running this single humidifier to try to humidify my entire condo...so it does have to be big as well... But, have time before I have to complete the order...so reviewing all the results....wouldn't be so painful if amazon's search was so fuzzy. I'm searching for just "humidifier", and its showing me things like cribs, pillows, swaddles, bassinets, dehumidifiers, evaporator coolers, air purifiers, bottle brush, nipple cleaner, heaters, bonsai tree, air conditioners...though the cigar related humidifiers probably aren't out of line, though I don't really think they should be in the department I'm searching under. And, the further out...finding humidifiers becomes less and less likely, but sometimes there'll be one here and there....though I'm sure if they weren't so fuzzy, I wouldn't have 10x the results to wade through....though sometimes the result is way near the end. But, not this time.

Anyways...that's pretty much what should just be in my amazon cart. But, if I add a few more items, I can get 6-month do not pay on my Amazon card....and I've already put off getting the humidifier too long already.

Cyberweek Activities

This being Cyberweek...I tried to cram some stuff in other than just recovery from Chicago Tardis into this week.

Though I haven't actually gotten to all the things yet...I felt that I should start this post before I forget all the things I wanted to cover. Too late &#58;&#110;&#111;&#58;

Anyways...one of the important items was new CO detector. I used to have a First Alert CO400?, battery operated CO detector that took a couple AA batteries and didn't do much else. I was looking to buy something like it again, except reading the negative reviews on amazon.com... a number of other people were complaining that unit disintegrates when you try to change the batteries. Which is why I was needing to replace my old one. So, I decided that maybe I would look at a different brand this time around.

Also noted that these things have like a 5 year life expectancy...though my First Alert CO detector was only a year old. I noticed that Kidde CO detectors claim a 7 year life span (though only a 5 year warranty). Though (in part due to Amazon 'recommendations') I got the Kidde KN-COPP-B-LPM, which has a digital display....showing current CO levels and historical levels, etc. Which I debated on whether I would want to know if there was a CO level, that wasn't alarming.

Don't know if I paid attention to the fact that it uses 3 AA batteries....one odd thing I've noticed, is that it doesn't say if I should replace batteries regularly....but I suspect it'll be part of the same routine with replacing smoke detector batteries.

Though I don't think I'll replace the CO batteries along with the smoke detector ones on December 25th (because of long DST, I had changed my bi-annual to be on or around June 25th and December 25th.) Though, I've already replaced the battery early in one of the smoke detectors. Odd, because there hadn't been any nuisance trips in some time...and it isn't one that is typically set off by these situations. (usually ones that nuisance trip is the detector in the living room [near the kitchen or the first bedroom from the kitchen.
