[ale] Crashed LVM machine, any ideas

[Nathan J. Underwood]

Weird Solution..

	Ok, so the client notified me (after this post) that they didn't have a 
good backup of that machine (apparently, swapping the tapes had become 
too much, so they just stopped).  So, I started digging into LVM, and 
trying to find some way to get it back up.  It was only 2 drives, one of 
which had a 100MB boot partition, 512MB swap, and the remaining of that 
drive and entirety of the other was the LVM.  I rebooted the machine, 
and noted that only 1 drive (the slave) was showing up in the BIOS.  I 
cracked the case (it's always the cable, right), unplugged and 
re-plugged the IDE and power cables to both drives, crossed my fingers, 
and booted the box back up.  No luck.  Turned it off, said a little 
prayer (something like 'please let this thing work cause I'm low on 
options').  Got sidetracked, and handled a few 'since-u-was' problems 
(i.e. since-u-was here, I can't print, my pr0n doesn't work, etc.). 
They shut the office down, so I had to head back the next morning.  Just 
for grins, I decided to power the machine back up, and it booted!!!  It 
wanted to do an fsck, so I happily obliged, and let it boot.  After it 
booted completely, I checked /var/log/messages for any errors (i.e. 
drive_cmd type errors, etc.), and found nothing.  Got bold, rebooted 
again (and again), and it just worked.  The box has now been up for 2 
days, and hasn't hiccup'd at all.
