    Hello vanderlay,

     

    What's the model number and FW version of the NAS?

     

    Welcome to the community!

    Are you using snapshots on the shares? If so, they could hold the data.

     

    Can you download the logs and copy/paste the content of the btrfs.log?

        Thanks for logs.

         

        Yes, this looks quite healthy. No where near full.

        It basically tells us that you have used about 380GB out of 2.7TB. The BTRFS chunk allocation looks good as well. Might just be the GUI messing up here.

         

        And can you still write to the NAS? Like transfer files to it?
