I did a compare with a backup I made of the /var system and there was nothing different, so it's still pretty weird. Either way, I'm ok for now, but I'll watch for the error again. I wish I knew what caused the systems to reboot in the first place. > Without knowing the cause of the crash, it's impossible to say.

Like it said though, rebooting made it show the correct devices for the drives and I haven't seen the problem since. I'm building a new system from scratch here though, so I'll see if I can simulate some failures (and reboots) to see if I can get a similar error. Thanks!
