ZFS pool disk retrieve

[Debabrata Paul]

Hi,

I am trying to retrieve a disk from ZFS pool but not having much luck. coming up with error every time. currently there is no pool nor the host as I installed fresh proxmox and setting up the drives.

sdd 8:48 0 3.6T 0 disk
├─sdd1 8:49 0 3.6T 0 part
└─sdd9 8:57 0 8M 0 part

proxmox or window can read the drive but cannot format it though. I also tried to use third party software like EaseUS, MiniTool partition but failed. also tried to use parted but didn't work.

any suggestion to bring my disk back will be much appreciated.

[sdd] tag#20 timing out command, waited 180s --> the disk is 99,9% dead --> get a new one.
I wish you don't come to this end as the saying goes "Destroy and re-create the pool from a backup source." - hopefully have one.

Is the ZFS pool mounted? Was this ZFS pool mirrored or RAIDz with some redundancy in case of a drive failure? That is the point of ZFS.
zpool status
zfs list
zfs import
If the drive is timing out, try add extra cooling or give it time to cool off and try again.
If you are not getting anywhere you might try gddrescue to get an image of the entire drive. Then work with the copy.
