RN102 snapshots taking up space, not showing up in GUI

Hi,   My NAS (RN102 with two 3TB disks in RAID 1)  is showing about one TB in snapshots against 1.36TB in data. However, deleting all snapshots from each share does not free up any space. Instead...

    I'm guessing that it's these two.

    ID 778 gen 2482609 top level 7810 path .purge/1547626945_sabnzbd
    ID 3610 gen 1581080 top level 778 path .purge/1547626945_sabnzbd/.snapshots

    Can you navigate into .purge and see the space usage?

     

    You could try manually deleting the subvolume

    # btrfs subvolume delete -c /data/.purge/1547626945_sabnzbd

      Sorry for being a n00b, but how do I navigate into .purge? 

      manually deleting gives me this:

      root@RN102:~# btrfs subvolume delete -c /data/.purge/1547626945_sabnzbd
Delete subvolume (commit): '/data/.purge/1547626945_sabnzbd'
ERROR: cannot delete '/data/.purge/1547626945_sabnzbd': Directory not empty

      Thanks in advance!

        Try deleting .snapshots first then.

        # btrfs subvolume delete -c /data/.purge/1547626945_sabnzbd/.snapshots
