Hi albback,
Do you have the snapshots enabled?
You can try running a volume balance. You can find that option under System > Volumes then click the gear icon on your volume then select Balance.

That's likely the issue then. If you don't have a backup of your data, you should take care of that first. BTRFS can misbehave if it runs out of free space, so your data is at risk. If you don't have a backup disk handy, then disable snapshots for now, and avoid writing more data to the NAS until you can make one.
Delete all the snapshots you don't care about (starting with the oldest). You do that from using the web UI - just select them, and right-click. You'll see a delete option. It will take some time for the space to come back after you delete them. After you get some space back, run another balance.
Another option (IMO better) is to do a factory default, reconfigure the NAS and restore the data from your backup. There have been improvements to the BTRFS file system setup since 2014, so you likely would see faster performance if you rebuild the NAS (especially on an RN102). If your firmware is very old, then update it after the factory default, and then do a second factory default.
You can prevent this problem from recurring by switching over to "custom" snapshots and explicitly setting retention. I set most of my shares to 3 months retention - which keeps the snapshot space reasonable for me. Though this does depend on how much file deletion or in-place modification you do. Shares that are used for torrent downloads or which hold on-line databases should have snapshots disabled.
Or of course disable snapshots altogether. Though I do find them useful, so I wouldn't do that myself.
hi Stephen.
im deleting all snapshots apart from 30/10/19 and 30/10/19 in all my folders,when will i get some storage back also can i add another hard drive without losing everything that is on the drive i already have.
