hidden snapshots wont delete

i am showing 1.36TB of snapshots - i only had them enabled on a directory with 200mb shared. i have tried to delete using the ssh to upgrade the snapshot - but no dice. i am running current firmware ...

Do you see the snapshots (via ssh) when you enter

# btrfs subvolume list /data

(use your actual volume name instead of /data if you are using flexraid)

If you can see them, then you could try manually deleting them with

# btrfs subvolume delete /path

using the full path of the snapshot (something like /data/sharename/.snapshots/xx/snapshot). Make sure you include the volume name - the btrfs list command doesn't include it.

If the deletion works, you likely will need to do a balance (and maybe a scrub after that) to reclaim the space.

  What is the name of your data volume (look on the volume tab of the web ui)?
