I have tried to import my pool using a variety of commands, however it always fails. This is after a clean reboot. I did hot-add a number of disks to the server and then subsequently used them to create the pool, and this is the first reboot since creating the pool, not sure if there is a relationship. Unfortunately there is some data on the pool which is not backed up and needs to be recovered if at all possible.
If i specify the device name, as in
sudo zpool import -d /dev/disk/by-id/ neo sudo zpool import neo
cannot import 'neo': one or more devices are already in use
If I instead just run sudo zpool import, I get
pool: neo id: 5358137548497119707 state: UNAVAIL status: One or more devices contains corrupted data. action: The pool cannot be imported due to damaged devices or data. see: http://zfsonlinux.org/msg/ZFS-8000-5E config: neo UNAVAIL insufficient replicas raidz3-0 UNAVAIL insufficient replicas ata-HGST_HMS5C4040ALE640_PL1331LAHGWAJH-part1 ONLINE ata-Hitachi_HDS5C4040ALE630_PL2331LAGD00RJ-part1 UNAVAIL ata-ST4000DM000-1F2168_Z301VKAC-part1 UNAVAIL ata-HGST_HMS5C4040ALE640_PL1331LAHGSVDH-part1 ONLINE ata-Hitachi_HDS5C4040ALE630_PL1331LAGD81AH-part1 UNAVAIL ata-WDC_WD40EFRX-68WT0N0_WD-WCC4EPFK6PYP-part1 UNAVAIL ata-WDC_WD40EFRX-68WT0N0_WD-WCC4EK2CU8SV-part1 UNAVAIL ata-Hitachi_HDS5C4040ALE630_PL2331LAGD08UJ-part1 UNAVAIL ata-HGST_HMS5C4040ALE640_PL1331LAHD0BNH-part1 ONLINE ata-HGST_HMS5C4040ALE640_PL1331LAHGXGSH-part1 ONLINE ata-HGST_HMS5C4040ALE640_PL1331LAHGXG6H-part1 ONLINE ata-HGST_HMS5C4040ALE640_PL1331LAHGW0DH-part1 ONLINE
However, ALL OF THESE DEVICES ARE PRESENT (e.g. I did a ls -l and there are symlinks for all of the UNAVAIL devices), and the few UNAVAILs I just checked with smartctl report healthy).
Considering I ended up in this state during a clean reboot (sudo shutdown -r now), I'm really hoping there is a way to recover the data. Any help would be greatly appreciated.
Thank you, Eric
