no image mounted at /var/lib/docker

I converted my cache drive to XFS from BTRFS. Now Docker isn't mounting the docker.img file:

root@karmic:/etc/rc.d# ./rc.docker  start
no image mounted at /var/lib/docker

root@karmic:/etc/rc.d# ls -al /mnt/cache/docker.img
-rw-rw-rw- 1 nobody users 21474836480 Mar 26 00:23 /mnt/cache/docker.img

root@karmic:/etc/rc.d# file /mnt/cache/docker.img
/mnt/cache/docker.img: BTRFS Filesystem sectorsize 4096, nodesize 16384, leafsize 16384, UUID=5b444563-10e4-45db-aafc-1a5acc33c9ce, 19472728064/21474836480 bytes used, 1 devices

Does the docker.img file need to be recreated for some odd reason like the underlying format of the cache drive?

No, but if it doesn't mount just delete and re-create the image, then add your apps from previous apps, all settings will be kept.
