Detach drive from mirror

[Papid1975]

I have a natively encrypted mirror (2 disks) and would like to remove one disk to us it otherwise. Couldn’t find anything in the GUI. Is there still a way to do that?

Used zpool detatch <poolname> <diskname>. Doesn’t seem to mess with the encryption or anything.

Yes, that is one way to do it.

Note that the removed disk is not necessarily usable as a ZFS pool. ZFS has a special method to remove a mirror drive, (or drives in the case of a multi-vDev mirror setup), that preserves the integrity of ZFS in the detached mirror(s);

zpool split pool newpool [device]

But, if you just wanted to use the disk for another reason and don't care about the existing data, then what you did was fine.

Not sure why not:
