I have a disk inside my server which has failed and I'm trying to figure out which one it is. I did not make a list of all serial numbers as I should have. I plan on doing this but in the meantime, can I pull any additional information from the running system?WARNING: Your hard drive is failingDevice: /dev/sdc [SAT], unable to open devicesmartctl result:$smartctl --all /dev/sdcsmartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.10.0-514.2.2.el7.x86_64] (local build)Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.orgSmartctl open device: /dev/sdc failed: No such deviceSince the disk is no longer online, is there someplace I can still query information on it?UpdateGrepped dmesg for sdc:$dmesg | grep sdc[   12.074540] sd 0:0:2:0: [sdc] 5860533168 512-byte logical blocks: (3.00 TB/2.72 TiB)[   12.074542] sd 0:0:2:0: [sdc] 4096-byte physical blocks[   12.083407] sd 0:0:2:0: [sdc] Write Protect is off[   12.083410] sd 0:0:2:0: [sdc] Mode Sense: 7f 00 10 08[   12.084143] sd 0:0:2:0: [sdc] Write cache: enabled, read cache: enabled, supports DPO and FUA[   12.798801]  sdc: sdc1 sdc9[   12.807266] sd 0:0:2:0: [sdc] Attached SCSI disk[716178.562173] sd 0:0:2:0: [sdc] Synchronizing SCSI cache[716178.562252] sd 0:0:2:0: [sdc] Synchronize Cache(10) failed: Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OKThen grepped for those drives in fdisk:$fdisk -l 2>/dev/null | egrep -i '^disk /dev+.' | grep 3.00 | sortDisk /dev/sda: 3000.6 GB, 3000592982016 bytes, 5860533168 sectorsDisk /dev/sdd: 3000.6 GB, 3000592982016 bytes, 5860533168 sectorsDisk /dev/sds: 3000.6 GB, 3000592982016 bytes, 5860533168 sectorsI only have three 3TB disks in this system and they are all online. However the last one is all the way at the bottom of the fdisk list at /dev/sds. If a disk drops out and then comes back online is it reassigned the same dev id or a new one? This might be the drive.
Where to get information on failed disk?
