zfs zpool issue

The disk was physically replaced and is shared among other zfs pools.  In my attempts to replace it I ended up running zpool remove diskpool01 c0t7d0 because my attempts at running zpool detach, zpool replace, etc. failed.

After removing it from the zfs pools I meant to add it back as a spare to each of the pools, but I mistyped and forgot to put spare on the line, so I ran:

zpool add -f diskpool01 c0t7d0

Now I have a diskpool that is 500 GB larger than it was before.  I need to remove the disk from that zpool and add it back as a spare.

Any help would be greatly appreciated.



RE: zfs zpool issue

Hi John,

Follow the below procedure

zpool offline diskpool01 c0t7d0

zpool status --> verify disk is offline or not

zpool detach diskpool01 c0t7d0

zpool status

zpool add -f diskpool01 spare c0t7d0 --> add disk c0t7d0 as spare to pool diskpool01.

If you have any questions plz let me know.
