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 of 6.10

ive tried, https://notes.ponderworthy.com/upgrade-snapshots-in-a-readynas

and https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/How-can-I-delete-invisible-snapshots/td-p/1352107

i can make new and delete just fine. but i am unable to see the "hidden snapshots" am i missing something?

    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)?
