ReadyNAS 4312 - 54TB usable full even though the only thing stored 49TB LUN
Hello, I'm having an issue with our ReadyNAS 4312, we're using it as VEEAM target, set up an iSCSI LUN 49TB in size. We had about 5-6TB of space left on the NAS outside of that LUN. We recently t...

I don't have software support on this NAS anymore, I couldn't even contact support.
If you (or your company) were the original purchasers, you should be able to purchase a support contract through my.netgear.com. You would need to use the account of the person who registered the NAS (or arrange to get that transfered somehow). JohnCM_S or Marc_V should be able to assist.

We recently tried to turn on snapshots for the iSCSI LUN and I must have chose too high of a retention rate or something. I now have no space left out of that 5-6TB and since the LUN is thick provisioned even though I have space left there I have no way to clear off space or delete these snapshots or half snaps or whatever is happening.
What firmware are you running?
You could enable ssh, and see any snapshots by entering
# btrfs subvolume list /data

Yes I tried responding to this post but i think it kept deleting because of spam. I got the feedback here below, i see i have this Veeam-Repo-01/.snapshots is this what I'm looking for? Can I delete this? Not sure what the command would be? Any ideas?

I logged in as root and ran the command, it came back with a listing of the volumes, there is one in there for my veeam-repo-01/.snapshots. I'm attaching the feedback from the command. Is it possible to delete this from the command line? I keep getting commit errors when I try to disable the snapshots. I assume because the NAS is completely full, but if I can't delete these snapshots then i dont know how I'll reclaim any space.

Yes, but there are no snapshots in there, so there are no subvolumes to delete.
I'm not convinced that your space issue is actually due to snapshots (though I don't know what is causing it),
You might want to run
# btrfs filesystem df /data
and post the results on a reply.
