Eeeexcellent -- My Fiendish Plan is Working!

Y'all must be tired of reading about my struggles with Hard Drives lately, but since that's all I've been doing all week, that's pretty much all I have to write about.

Things have been going quite well today. The exhaustive tests of the hard drive I've been doing for the last 5 days came out flawlessly so it looks like I've got another 80 Gig of storage. I've already put it to use as a buffer for helping me move all this stuff around as I perform various recovery and reorganizing tasks.

Now that the MythTv box is no longer doing disk tests I've gone and swapped the 8GB drive it had for a 20GB and, modulo a few reboots to try different drive jumpers, its all working fine. Right now its continuing the MythTV install that it aborted due to lack of space several days ago. Once that program is installed, I'll see if I can get an X session to run so I can boot into Gnome. After that, I fear it may be repurposed to do disk tests again.

The 500GB drive that I imaged (and from which image I am recovering mucho files, even as I type) seems to have some bad sectors. I knew that after the first time I imaged it. However this time it seemed to have more. This is not a good sign. So, its going under the old reconditioning regime and it will afterwards either report a flawlessly working drive, or it its getting replaced since its still under warantee.

Once I have a trustable 500GB backup drive again it will be time to bite the bullet and erase the 200GB system image backup from over a year ago, which has been my backup-backup through all of this. I will then use that drive to *downgrade* my current system from 500GB to 200GB, freeing up another 500GB drive. This seems reasonable as most of the spare space on my machine is being used for storage and once I have a MythTV/storage server, that should not be an issue.

Then the 2x500GB and 1x1TB drives will all get stuck into the MythTV box to supplement the puny 20GB system drive it has, and I will be the proud owner of a 2TB storage thingee.  I'm not going to go with any raid redundancy or anything at first (although I will probably merge the drives into a single 2TB filesystem via raid or LVM2) as my experiences on my web server is that the raid software crashes more often than the hard drives its meant to protect.  At some point I WILL want to come up with a reasonable backup solution, like a removable 2TB drive or something, but that can wait for a future upgrade plan.

(1) If the drive is failing and still under warranty, replace it. If it's getting worse, don't even try to recover it -- If it works, the drive will still get worse, and you'll have a harder time getting the warranty honoured. If you use it anyway, make sure it's on a redundant RAID, because it will fail.

(2) I've *never* had trouble with the RAID software failing. Instead, it has enabled me to continue running when one of my disks failed. The only sign of failure was an email I got from the RAID system telling me one of the drives had failed.

I'm a geek! I love hearing about computer-related stuff! Post away! :)
