About once every 4-5 days, the server loses its connection to the SAN and I get these messages in my log: May 19 09:01:08 nutcracker scsi1 (0:0): rejecting I/O to offline device May 19 09:01:08 nutcracker metapage_read_end_io: I/O error May 19 09:01:08 nutcracker scsi1 (0:0): rejecting I/O to offline device May 19 09:01:08 nutcracker metapage_read_end_io: I/O error May 19 09:01:08 nutcracker ERROR: (device dm-4): DT_GETPAGE: dtree page corrupt May 19 09:01:09 nutcracker scsi1 (0:0): rejecting I/O to offline device May 19 09:01:09 nutcracker metapage_read_end_io: I/O error May 19 09:01:09 nutcracker ERROR: (device dm-4): DT_GETPAGE: dtree page corrupt Nothing unusual shows up in the SAN logs. I've already adjusted the cache flushing on the SAN and changed the scsi timeouts to 45 seconds. I asked emulex about it, but I'm wondering if this is something in the scsi layer. Has anyone else had similar problems or know what the problem may be? Thanks, Alex
