Deleting Redundant Time Machine Backup
I noticed that my NAS was low on space, but the numbers didn't add up, so I checked the file structure and notice there is approximately 1TB of timemachine backup that was for a machine that is no longer with me.
I tried to delete the folder through finder by connecting through smb using admin as well as the admin user account, neither worked and through SSH it says that the operation is not permitted, even when I'm logged in as the admin...
Any ideas how I can delete the redundant backup and reclaim some storage space?
Thanks!

This worked for me, now I can see the list, but how delete the folder? I assume rm will not work?
# btrfs subvolume delete -c /path
using the fully qualified folder name (/data/... )
The -c tells btrfs to wait for the deletion to complete. You can omit that if you want.

Normally you log into ssh using root, not admin.
I don't use time machine, but I suspect the folder is actually a btrfs subvolume - if so, rm won't delete it. Try running
# btrfs subvolume list /data
from ssh, and see if it is in the subvolume list. data is the default OS-6 volume name, if you are using flexraid you'll need to substitute your actual volume name.
