Snapshots taking a lot of space but all snapshots are disabled.
I have two Readynas 316 boxes. I have disabled all snapshots on all shares. I have removed all snapshots from the shares. The problem is one box is reporting 1.8 TB of shapshots and the other is repo...
Found it.
Using btrfs command to delete the subvolum.
btrfs subvol delete /data/._share/name-of-folder/.snapshot/name-of-subfolder
Can you send in your logs (see the Sending Logs link in my sig)?
Logs sent.
I saw this thread and it resolved the issue on one of my boxes but not the other. The box that it didn't work on appears to have snapshots that belonged to an old share that isn't on the NAS any longer. How do you locate and delete those? They are located in the ._share directory. I can see the directories listed there. Of the 11 directories listed, 6 are no longer shared. An attempt to delete the old shares results in an error because they are set as read only.
Any thoughts?
If you're referring to https://community.netgear.com/t5/Using-your-ReadyNAS/Deleting-Files-and-Snapshots-does-not-free-up-space-UI-shows-no/m-p/1119714#M113322
This is to force the upgrade of old snapshots.
According to your logs, you do have old snapshots, but also some snapshots that should be deleted but aren't. This is because the BTRFS volume is completely full (fully allocated). As you need space to delete data, it's blocked there.

You should also keep an eye on your HDDs. They're getting old and two of them are showing some errors (nothing urgent for the moment).
Yes, that was the thread. I'm not sure why It didn't show when I posted. Anyway, the commands
# touch /.force_snapshots_upgrade # systemctl restart readynasd
worked on one box but not the other. I believe it's because those shares don't exist any longer. So, it boils down to how to delete directories with thousands of files that are also read only?
