Extra devices in cache pool

[zachmo826]

I recently went to try to replace a cache drive in a 2 device cache pool. Made a few mistakes with leaving the old cache drive connected, but now have two cache drives in the pool in the GUI. When I run 'btrfs fi show /mnt/cache' I get the following output:

Label: none  uuid: de367c3c-6d81-436c-810a-1fddd25394321e
        Total devices 3 FS bytes used 835.71GiB
        devid    2 size 931.51GiB used 839.03GiB path /dev/sdb1
        devid    3 size 931.51GiB used 121.00GiB path /dev/sdd1
        *** Some devices missing

 

This is setup in RAID1, but it's currently rebuilding the new drive, which is why the storage used amounts don't match.

Any way to get this device count back down to 2?
