zfs zpool issue

[johngiggs]

I had a zpool spare disk that failed and was replaced.

pool: diskpool01
state: ONLINE
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
diskpool01 ONLINE 0 0 0
raidz2 ONLINE 0 0 0
c0t0d0 ONLINE 0 0 0
c1t0d0 ONLINE 0 0 0

c0t7d0 ONLINE 0 0 0
spares
c0t7d0 UNAVAIL cannot open
c5t7d0 AVAIL
c4t7d0 AVAIL

errors: No known data errors

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.

Thanks,

John

Hi John,

Follow the below procedure

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