Snapshots - reclaiming storage space

[itnorm]

ReadyNAS 312

Just updated firmware to 6.8.1

It is reporting snapshots at 168GB:

I fully deleted all snapshots:

I have done:

# touch /.force_snapshots_upgrade
# systemctl restart readynasd

I have restarted several times.

I have done a balance.

How do I clear the space being reported for snapshots?

Update:

ReadyNAS RN312 (for some reason the model pulldown would not show this model), that's why it is empty

firmware is 6.8.1

btrfs subvolume -list /data

Does list some snapshots (I think), i.e. Pictures/.snapshots

doing an ls -all gives

root@nas1:/data/Pictures# ls -all
total 32
drwxrwxrwx+ 1 guest guest 20 Mar 17 2016 .
drwxr-xr-x 1 root root 324 Jun 1 13:56 ..

I have tried a second 

# touch /.force_snapshots_upgrade
# systemctl restart readynasd

Now the System->Volumes status shows that snapshots are 0 and free space is 349GB (screenshot 1)

but in System->Overview ther is still a yellow section in the pictorial under the /data indicating sme space for snapshots and it says free space 189GB (screenshot 2)

Trying another Balance

Pictures/.snapshots is just the place where snapshots are stored for that share. There would need to be subvolumes beneath that for there to be snapshots e.g.

Pictures/.snapshots/1/snapshot

You could try disabling quotas on the volume, then re-enabling them to force a quota rescan.

The forcing of snapshots upgrade is for upgrading old snapshots from pre-6.2.0 firmware.

Another Balance command did not change the snapshot size

Tried another

# touch /.force_snapshots_upgrade
# systemctl restart readynasd

And now snapshot size agrees

Where are quotas?

Quotas are enabled/disabled in the volume settings wheel.
