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.

Switch to Widescreen display, and Orac loses a brain.

Well, thought it was going to be another quick project....ended up taking the whole afternoon and then some.

I had gotten some speaker options using Amazon Prime, so that I could swap out the old 17" LCD monitor with built-in speakers for the Vison 21.6" MW22E-BAD monitor that had been bumped from Zen recently.

I decided I wanted something <$25 and USB powered, and I bought two choices...figuring that the other would go on Orac, since I've been wanting sound on there too for a while. I went a Coby Portable MP3 Speaker System CSMP48, Black and an Altec Lansing iML237USB ORBIT Ultra Portable USB-Powered Speaker.

I decided that I got with connecting the Coby to Gumby and putting it below the monitor...turned out it was the only one for the situation. The Coby has a 3.5mm jack to connect to the output and a mini USB jack with cable to power it. While the Altec only has the USB cord...it isn't just powered by USB, but it does its own sound. While that would work on either computer, it wasn't really what I had in mind for Gumby....or Orac. So, the Coby went in place and then I went to work on swapping the Vison 21.6" monitor into place.

Things looked weird on all computers, since I had to tell each computer about the change in display.

Gumby, Windows XP was a problem...in that it wouldn't let me set 1680x1050 at first. Eventually, I uninstalled the driver, rebooted and now it shows tons of modes that I'm not interested in. I set it to 1680x1050 and 60Hz and triggered an autoconf and done. I didn't decide on 60Hz right away, but that's where I settled. The other choices were 70Hz and 75Hz.

Then, BOX....I used the Monitor app to change things and it saw that the monitor was different and settled on 1680x1050 and 70Hz (again not first choice, but where I settled). Why...when they were all 75Hz...the had slightly different ideas on where the image was centered, so I went with 3 different verticals so the monitor would have the desktop properly positioned for all 3. Wonder what I'll do when I get LHAVEN going? &#58;&#104;&#109;&#109;&#58;

Then ORAC, which was harder....the Monitor app wouldn't see that resolution, and reconfigure has apparently gone away. Eventually, I discovered xrandr and cvt and got it working. As 1680x1050 and 75Hz.

Mostly.....

Morning Orac outage

Well, Orac was being somewhat unresponsive this morning.... Looks like early this morning the system stopped answering to Cacti, with the temperature of the GPU rising to a new high. Don't know what the high would've been, because there was no snmp data for a while. GPU temp did recover, but the display did not.

Ended up rebooting, needed the excuse to see external journal work....

Once backup, I switched back to internal journal...but one of maximum size rather than default size. And, then shutdown the system to extract the PCI Compact Flash card. During the reboot to see external journal work...I realized that I wasn't likely to see much performance gain from getting faster compact flash since the card itself was only UDMA/66. So the 133x CF is already faster than the card?

Probably should've fsck'd manually after the switch back....some discussion thread suggested doing this after fiddling with journal settings. But, its fsck'ng now after the boot back up. Apparently superblock had invalid external journal superblock hint? And, auto fsck failed, requiring manual fsck.

Downside of internal journal is that it can only be a max of 400MB (an improvement from the 128MB default I had before)...but that's only like 0.01% of my total space. And, there was a discussion thread that seemed to suggest a journal size of 0.2% would yield better improvement....I didn't do the whole 16GB CF card...though wonder how much that would've helped.... But 0.2% would call for a journal of ~10.9GB. Suppose I could turn off data journaling, especially since there are files that backuppc puts down that are bigger than the 400MB journal. Though I think the ordered/writeback modes usually just do metadata journaling, while I had switched it to data journaling when I was playing with external journals...but I didn't switch it back.

Wonder which of writeback or ordered would be more optimal for this FS? &#58;&#63;&#63;&#58;

Got another brain for Orac

So, the other day, I was poking around on NewEgg.com, trying to decide if I wanted to get the upcoming ShellShocker. I spotted a single slot GT440 for a good price among the daily deals. While I was looking around, I saw other things that caught my interest...a powersupply tester. Or things that I needed to go with the card, like a DVI-I to VGA adapter. Also decided to grab a new fan, since it is probably only a matter of time that the fan in the other drive array on Orac to fail.

I ended up not getting the ShellShocker item.

I've been eyeballing getting a single slot 400 Series card for Orac for a while. Was originally going to get a 200 Series, and I did actually get one in a different ShellShocker deal. But, when I opened up Orac, I realized it wouldn't fit....due to its huge fan.

Not sure what I'll do with that card. But, I had been looking at 400 Series, because Zen came with a GT420....which I've learned is a pretty horrible, compared to the rest of the line. Especially when it comes to doing BOINC. I'll probably go GTS450 or GTX460....single slot, though I need to take a look inside someday to see if there's actually juice in there. Otherwise, maybe I'll want a second one of these...

So, I had picked up the card from the UPS Store on Friday...but I didn't get around to installing it today. I stopped checkarray before I shutdown. I changed the scheduling of checkarray to spread things out better.

Though I had a brief distraction this morning on another matter, which I'll be posting about soon...

But, I went and put it in...its a pretty tight fit sitting next to my PM eSATA card.

I wonder if I'll look into a slot fan to go in the open PCI slot there....the lower PCI slot is where 4 other eSATA....oh wait, I had gotten a PCI card that I was going to put into Orac. I wonder what happened to that project....

I got me an HP....

... an HP Pavilion Elite HPE-450t, customized with things like:

  • Intel Core i7-870
  • 9GB DDR3-1333MHz SDRAM
  • 1.5TB RAID1 (2x1.5TB SATA HDDs)
  • Windows 7 Professional 64-bit
  • 2GB NVIDIA GeForce420

Should be good for doing BOINC &#59;&#68;

Now, I bought this system customized expecting to pretty much plug it in and go, only having to add externally attached peripherals to complete things. Though I do plan to do upgrades in the future, specifically I got the the 3 DIMM ( 2x4GB + 1GB ) configuration of slightly more memory so that I could potentially take it to the 16GB max at a future date without having to buy all 4 new DIMMs. If I had bought the 8GB configuration, it would've come as 4 2GB DIMMs. Anyways...without doing anything else first...I just had to take a peek inside.

Now, I don't know if it was that I got a Core i7-860 Dell computer at work (replacing a P4-2.8Ghz machine, so slower than TARDIS - a P4-3.2GHz w/HT machine) or ordering this computer...but TARDIS had seemed to get slower and slower, to pretty much insufferable these last few days. Still not ready to turn new system on....more later.

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.
