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 -- dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
