G'day,
I've got a OpenSolaris server n95, that I use for media, serving. It's uses a
DQ35JOE motherboard, dual core, and I have my rpool mirrored on two IDE 40GB
drives, and my media mirrored on 2 x 500GB SATA drives.
I've got a few CIFS shares on the media drive, and I'm using MediaTomb to
stream to my PS3. No problems at all, until today. I was at work (obviously
not working too hard :) ), when I thought that I really should scrub my pools,
since I hasn't done it for awhile. So I SSHed into the box, and did a scrub on
both pools.
A few minutes later, I lost my SSH connection... uh oh, but not too worried, I
thought that the ADSL must've gone down or something.
Came home, and the server is in a reboot loop, kernel panic. Nuts...
Booted into the LiveDVD of snv_95, no problem, set about scrubbing my rpool,
everything is good, until I decide to import and start scrubbing my storage
pool... kernel panic... Nuts...
Removed the storage pool drives from the machine, no problem, boots up fine and
starts scrubbing the rpool again. No problems. Decided to more the storage
drives over to my desktop machine, try to import.... kernel panic...
So, the trick is, how do I fix it?
I've read a few posts, and I've seen other people with similar problems, but I
have to admit I'm simply not smart enough to solve the problem, so, anyone got
any ideas?
Here's some info that I hope prove useful.
