Can't delete unused docker container

My binhex-rtorrentvpn container had an error of some kind during an update, and became un-deletable. Created new container to get around the error, different name, no biggie. But the old container still can't be deleted. It doesn't show up when I run "docker images" in the terminal, but I can run "docker inspect" on the container ID given in the Unraid gui. Running "docker rm" on the container ID returns the following error:

docker rm  7609238e662c
Error response from daemon: container 7609238e662c9c068960494cd69752316ca56c33b968007e77fd357945593d0a: driver "btrfs" failed to remove root filesystem: Recursively walking subvolumes for /var/lib/docker/btrfs/subvolumes failed: error walking subvolumes: lstat /var/lib/docker/btrfs/subvolumes/aa4b5954e6d2c96970f5ce6ab5071d659f8f99cfddc6de6f670b1d4f58ca8eca/usr/share/webapps/rutorrent/plugins/retrackers/lang/es.js: input/output error

And the system log shows the following error when I run the "docker rm" command:

Feb 13 01:27:08 Tower kernel: BTRFS error (device loop2): bad tree block start 0 347701248
Feb 13 01:27:08 Tower kernel: BTRFS error (device loop2): bad tree block start 0 347701248

I suspected a problem with my cache pool, but scrubbing the cache showed no errors. Any other way to delete the bad container?
