Unable to erase inaccessible snapshots in ReadyNAS 424
Hi, I have a ReadyNAS 424 and even after I have disabled and deleted all the snapshots in it. But still 1-1.5 TB s space is alloted to it. I have tried the methos from, https://forum1.netgear.com/t...

The command isn't recursive, so it won't delete subvolumes inside another subvolume. So if you just tried deleting the main snapshot folder for the share with that command, it will fail.
Try listing the snapshots with
# btrfs subvolume list -s /data
and then delete each snapshot (one at a time) using the full path name.
The other approach is to destroy the volume, recreate it, reconfigure the shares, and restore the files from your backup.
Hi. Thank you for the reply. I have previously tried deleting using SSH and with root user privileges. I used various Linux commands to delete. But I got errors saying they were read-only file system. I also tried to change permissions with chmod -Rf 777. But nothing worked.
I tried the command you gave just now as well. But it returned this,
ERROR: Could not destroy subvolume/snapshot: Directory not empty
Any other method to delete these read-only folders along with the complete directory structure in one go? Please let me know. Thank you.

OMG Finally!!! It works! All the snapshot allocation is cleared! Thank you so much! Now running a balance operation.
Here is the display from using # btrfs subvolume list -s /data

And finally the snapshot allocation was cleared. I will post the web UI page screenshot again after completion of the Balance operation. Again thank you so much!
