Hi,
I have a customer in a very remote location in Africa with the following
symptoms on a IBM serveRAID Linux system with dm and reiser3. I struggle
to get any info (all telephonically) but so far I have:
Buffer I/O error on dm-0
Lost page write due to I/O error
reiserfs: dm-0 journal write error in flush_commit_list
Is this necessarily h/w failure (like 2 or more disks failing in the
array), or are there other common problems related to these errors?
(perhaps cabling?)
Really, I simply need to confirm whether there could ever be a software
cause for this?
Regards
Niel

There should be a few scsi error messages in the log prior to "Buffer I/O
error on dm-0" that would provide info on why the scsi command did not
complete. This will answer all your failure isolation questions, but it
will help narrow it down to the next level.
