Missing Swap on 2 of 10 disks?

[lrosenman]

I have a 10-disk VDev that I think I'replaced a couple of disks via the CLI:

and the SWAP partitions on mfid0/1 are NOT being used, but the ones on ada0/1 (boot) and all the other mfid* drives are:

this is on TrueNAS 13.0

Is there a way to "fix" it, or am is just out of luck? I don't really need the swap, but I'd like to know.

Also, the "disks" menu item does not show the 10 disks for data

Ideas?

While there's still the "replace disk workaround" on 13.0 (waiting on U1 for the fix to the GUI for that), you can't do the normal replacement of a disk in the GUI... but let's assume that we're talking about 13.0 U1 or 12.8 U1...

Offline the disk

Wipe it.

Replace it with the same disk in the GUI (you may need to force a refresh of the GUI in the browser to have that disk appear again as an option).

Wait for resilver to complete.

and the SWAP partitions on mfid0/1 are NOT being used, but the ones on ada0/1 (boot) and all the other mfid* drives are

Actually that's quite normal... I think it goes to a maximum of 8 partitions, so if you have more than that available, it makes sense you have some unused ones.

Aha, that ALSO explains when I added 6 new 8TB drives it set swap partitions up, but isn't using them. Thanks!
