Ready NAS turned read only

Today my RN102 seemed to turn read only. Noticed that Ready cloud was terminated and wondered if the two has anything to do with each other. 

 

No matter what the cause is, how can I solve this?

    No.

    Download the log zip - you'll likely find either BTRFS errors or disk errors in systemd-journal.log, kernel.log, or system.log.

     

    The first step is to back up your data, as it is at risk,

      I want to emphasize that re-booting is NOT the next step.  The volume goes read-only to keep it as intact as possible when a BTRFS error occurs.  Many have come here who originally saw this and decided to re-boot, only to find the volume would no longer mount at all.

       

      You are likely going to end up having to at least destroy your volume and re-create it, or possibly do a factory default to be sure you have a "clean" volume, so you are going to need that backup and should get it while you can.  Hopefully, you've been backing up all along, and it's just a matter of doing a final sync.

      Where do I find that log?

       

      And it feels like it's something else. I have two external hdds connected to the ReadyNas and I can't write to them either.

        There's a download link on the logs page.  Click on that to get the full log zip file.

        It's definitely triggered by something wrong with the file system.

         

        No matter what it is, your data is very much at risk.  If you don't back it up quickly, you could lose it all.

         

        As Sandshark says, don't reboot or take other actions on the NAS until after you back up the data you need to preserve.
