Hot spare kicked in now trying to reset things.

[Dirk]

Drive dropped out and spare kicked in I assumed a dead drive. Ordered another and burned it in and went to replace it to find a cable had poped off (yes, I did check first but hard to see anything in a Node 304) Re seated the cable and all drives came online. However I'm trying to sort out how to get the spare re-set as a spare and If I'm not mistaken the pick below shows two drives designated as spares now.

Appreciate any help on sorting it out.
Thanks

Well, apparently you need to do it from the command line. Detaching the spare from the data pool does not work from the GUI and throws a python error (confirmed by two other threads and user experiences.)

From CLI:
zpool status #to get the ID of the spare that is still in the data pool and shows unavailable in the GUI
zpool detach <poolname> gptid/<big long hash of drive id>

Can I assume there is a flaw in the GUI process that tries to do the same thing?
