Checking in on the health of my array, I noticed my hot spare is now listed as “in use”. My pool consists of six drives, arranged as two z1 vdevs of three drives each.
The status readout shows seven drives in use in the pool. I’m thinking a drive timed out or something, which caused the spare to take over, but then the failed drive started working again?
Here’s the output from zpool status. I need advice on what it means, and how to remove the “extra” drive and get it back to being a hot spare.
