I get a lot of these from both sdb and sdc Oct 11 23:00:03 cloud.warrenhughes.net kernel: sd 0:0:1:0: [sdb] UNKNOWN(0x2003) Result: hostbyte=0x00 driverbyte=0x08 Oct 11 23:00:03 cloud.warrenhughes.net kernel: sd 0:0:1:0: [sdb] Sense Key : 0x3 [current] Oct 11 23:00:03 cloud.warrenhughes.net kernel: sd 0:0:1:0: [sdb] ASC=0x11 ASCQ=0x0 Oct 11 23:00:03 cloud.warrenhughes.net kernel: sd 0:0:1:0: [sdb] CDB: opcode=0x88 88 00 00 00 00 00 11 b3 e1 98 00 00 00 08 00 00 Oct 11 23:00:03 cloud.warrenhughes.net kernel: blk_update_request: critical medium error, dev sdb, sector 297001368

Oct 10 07:42:36 cloud.warrenhughes.net kernel: sd 0:0:1:0: [sdb] 15628053168 512-byte logical blocks: (8.00 TB/7.27 TiB) Oct 10 07:42:36 cloud.warrenhughes.net kernel: sd 0:0:1:0: [sdb] 4096-byte physical blocks sd 0:0:1:0 starts out as sdb, but then goes a bit crazy somehow and eventually gets offlined Oct 11 23:55:24 cloud.warrenhughes.net kernel: sd 0:0:1:0: rejecting I/O to offline device And then reappears as sdo Oct 11 23:57:56 cloud.warrenhughes.net kernel: sd 0:0:1:0: [sdo] 15628053168 512-byte logical blocks: (8.00 TB/7.27 TiB) But no further scsi messages for this drive while Btrfs now complains about sdo instead of sdb. Seems to me that this device is confused even about its own error reporting. Anyway both sdb and sdc were having problems at the same time.
