Discs Labelled as Spare (Moved from FreeNAS area)

[PeterSM]

TrueNAS-12.0-U4
I have a pool "Data" that has recently had discs fail which I have now replaced and the pool is labelled as state "ONLINE"
But I have 3 discs labelled as spare, da2 twice!

zpool status Data gives:

Code:

root@freenas20:~ # zpool status Data
  pool: Data
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
        still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(5) for details.

Why is da2 shown twice?
As da6 is part of the pool how do I stop it showing as spare?
Basically i want to tidy up the pool and remove any spare discs as I now intend to use cold spares.
Thanks for any help.

Why is da2 shown twice?

It's a designated spare (so shown as unavailable in spares), but has been brought in to "spare" for a disk that was designated as failed at some point, so you see it together with the "replaced" disk in the spare-2 group.

As da6 is part of the pool how do I stop it showing as spare?

You either need to detach the original and leave the spare or detach the spare and it will go back to being a spare... see here https://illumos.org/books/zfs-admin/zfs-admin-ebook.pdf

Page as numbered on the "paper" 53-54 for the 3 possible options and what to expect.
