Hot Spare still in use after replaced disk (cannot free up the hot spare)

[Bill Calkins]

I have a 6 disk raidZ1 with a hot spare. da0-da5 , da10 is the hot spare
da4 failed and da10 (spare) kicked in and took over.
I added a new disk to an empty slot and it's da11. I offlined bad disk da4. I replaced da4 with da11 The pool is resilvered, state online
My spare is still in use in the pool and the spare is labelled INUSE

How do I get my spare out of the pool and back in the AVAIL state? I offlined it but the pool goes into degraded state. I tried offline/detach- but it gives an error
The UI still shows the pool as a 6 disk pool, but it's using 7 good drives.

Note: Attachment it what the pool looked like before I replaced the disk. I also go through the steps I performed.

zpool detach data gptid/2511dac0-42c7-11eb-8bde-4cd98fb8f3f4 should do it.

 

[Bill Calkins]

That worked! Thank you sretalla!

As I stated, I offlined then detach but that gave me python errors. However, I did do it in the UI, so maybe that's why. But simply detaching and giving the full gptid worked. Maybe it was doing it from the CLI and giving the full ID name that worked.

I haven't seen any evidence that convinces me that the GUI is well equipped to handle anything after adding the spare to the pool... I have only seen success from the CLI with "returning to normal" (a few different versions of what "normal" might be).
