[linux-lvm] SCSI/LVM problems after power outage

It looks like device 2 is having issues:

SCSI disk error : host 2 channel 0 id 2 lun 0 return code = 18000002

However, it has been several years since I worked with Sun machines, so I
could be wrong.  Regardless, it doesn't sound like an LVM issue, but a
hardware issue.  Unfortunately, I can't offer much recovery advice - most of
my LVM experience is with HP-UX, and we use mirroring (RAID-1) at work -
just unplug the bad drive, plug in a new one, and do a vgsync.  I think you
can add a replacement drive to the VG and use pvmove to try and move the PEs
from the bad drive to the new drive, but I wouldn't take my word for it...

Hi all,

After a power outage, our ftp server with LVM has not survived very well.

System: UltraSparc II, Linux 2.4(2) + io.path + LVM 0.9.1beta6

All normal ext2 paritions were fsck'd fine, however, the volume is having
problems.

The syslog has a lot of SCSI errors:

How can I find out which disks are having problems, and what are
possibilities to fix this?
