These are coming from scsi_init_io() in drivers/scsi/scsi_lib.c. I don't know what it means, but I'm inclined to think that it indicates a software bug rather than a hardware error. > Jun 25 09:27:04 nicfs2 kernel: device-mapper: dm-multipath: Failing path 8:96. > Jun 25 09:27:04 nicfs2 kernel: cfq: depth 4 reached, tagging now on > Jun 25 09:27:04 nicfs2 kernel: end_request: I/O error, dev sdc, sector > 1592060824 > Jun 25 09:27:04 nicfs2 kernel: device-mapper: dm-multipath: Failing path 8:32. > Jun 25 09:27:04 nicfs2 kernel: end_request: I/O error, dev sdc, sector > 1592062936 I'm not sure if dm-multipath may be responsible. > Following that was a flurry of JFS errors.

Seems reasonable, but I'll let others comment. > Chris Thanks, Shaggy -- David Kleikamp IBM Linux Technology Center ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
