I just swapped out a drive which was involved in a gmirror swap. This is the current status:

$ gmirror status
       Name    Status  Components
mirror/swap  DEGRADED  da0p2 (ACTIVE)
                       da2p2 (ACTIVE)
                       da3p2 (ACTIVE)
                       da4p2 (ACTIVE)
                       da5p2 (ACTIVE)
                       da9p2 (ACTIVE)
                       da10p2 (ACTIVE)

Here is how I can fix that:

sudo gmirror forget swap

The above tells gmirror to forget about components which are not connected. As you can see here, it makes gmirror happy.

$ gmirror status
       Name    Status  Components
mirror/swap  COMPLETE  da0p2 (ACTIVE)
                       da2p2 (ACTIVE)
                       da3p2 (ACTIVE)
                       da4p2 (ACTIVE)
                       da5p2 (ACTIVE)
                       da9p2 (ACTIVE)
                       da10p2 (ACTIVE)
$

Now I add in the swap partition on the newly inserted drive:

$ sudo gmirror insert swap da1p2
gmirror: Provider da1p2 too small.

Oh. That’s because the swap partition on the new drives is 2GB. On the existing drives, it is 4GB. I will have to wait until all my drives are replaced.

Or I could destroy the gmirror now, and create a new gmirror based on the 2GB partitions from the newly inserted drives.

Decisions. Decisions.

I will delay that decision for now. Which means: I’ll wait.
