RAID, ReiserFS, Suspend Troubles

This made me chuckle.

Which is good, since my RAID1 array died on the workstation. (Note to self: when in Gnome, never ever click "Suspend" instead of "Shutdown".) The hardware itself is okay, but . . . Caused a hard lockup when I returned from suspend. Hit the magic OFF button on the box itself, rebooted, and blam:

Kernel panic, unable to mount root VFS, bad superblock magic, not starting arrays, yadda yadda.

Oops. Since I couldn't start any arrays whatsoever after rebooting with a LiveCD, I ended up running reiserfsck --rebuild-sb and --rebuild-tree on the actual partitions, not the raid (md) devices. Right now, / is resyncing in the background; I decided to go ahead and recreate all the arrays once again, following the Gentoo RAID quickinstall howto. It's sort of a scorched earth fix that's one step short of wiping the disk and reinstalling. Once the disks have finished resyncing, I'll try running the reiserfsck commands on the raid arrays themselves, just in case.

Otherwise, I'll have to nuke 2 months of data, productivity, and my complete backup from the laptop that I just wiped and reinstalled. I'm currently typing from said laptop right now, and I will be extremely pissed if I have to kill some 40GB worth of priceless data. My entire old /home dir is currently "backed up" on the nonfunctioning desktop.

*crosses fingers*
