Hi,
I had a hot spare used to replace a failed drive, but then the drive appears to
be fine anyway.
After clearing the error it shows that the drive was resilvered, but keeps the
spare in use.
zpool status pool2
pool: pool2
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
pool2 ONLINE 0 0 0
raidz2 ONLINE 0 0 0

spares
c10t22d0 INUSE currently in use
errors: No known data errors
How can I get the spare out of the pool?
Thanks,
Brian
Hi Brian, You could manually detach the spare, like this: # zpool detach pool2 c10t22d0 Sometimes, you might need to clear the pool error but I don''t see any residual errors in this output: # zpool clear pool2 I would use fmdump -eV to see what''s going with c10t11d0.

Thanks, that did it. I thought "detach" was only for mirrors and I have a raidz2, so I didn''t think to use that there. I tried replace/remove. I guess the "spare" is actually a mirror of the disk and the spare disk and is treated as such.

Hi Brian, Yes, the current wording around detaching spares is kind of confusing for RAIDZ configurations. I will fix that shortly.
