11.2 hot spare swapping help

[TidalWave]

Hi Guys,

So we have a degraded HDD in a pool with multiple RAIDz2. We have two hot spare drives and 2xRaidz2 stripes with 10 disks each. So we have 22 hard dirves.

One of the drives in a Raidz2 array became degraded. I think it has auto resilvered. But I decided to right click on degraded HDD and selected offline.

There is a spare underneath it under the same Raidz2 list of disk. But the same spare is also still listed under the spare disk list and shows as unavailable. Am I suppose to right click on the unavailable spare and click remove? Will that move the hot spare into the Raidz2 that had a degraded disk?

Take a look at the photos and let me know what is the best course of action, please.

Is this still an issue for you? If so, please post the full output of zpool status within code tags.

I'm with the same issue right now. What is the correct workflow?

Code:

  pool: pool
 state: DEGRADED
status: One or more devices has been taken offline by the administrator.
    Sufficient replicas exist for the pool to continue functioning in a
    degraded state.
action: Online the device using 'zpool online' or replace the device with
    'zpool replace'.

The spare has taken up duty to replace the failed drive. At this point I would select "Replace" from the 3-dot menu of the failed drive to make the change permanent and proceed to test this drive.
