Orphaned snapshot prevents backup

[RonV42]

I removed an old ZFS volume and didn't check to see if snapshot was still on that volume for one LXC. Every time I run a backup on this LXC I receive and error. Here is the output of the backup:

root@proxmox2:~# vzdump 111 --storage brains-nfs --mode snapshot
INFO: starting new backup job: vzdump 111 --storage brains-nfs --mode snapshot
INFO: Starting Backup of VM 111 (lxc)

ERROR: Backup of VM 111 failed - storage 'local-zfs' does not exist

Any idea's on how to remove the reference to "local-zfs"

Thanks.
