When adding file from PC to ReadyNas I receive error "The Disk is Write Protected"

I have had my ReadyNAS up and running for a few months and today when I tried to copy files over from my Computer hard drive to my NAS system I am getting an error "This Disk is Write Protected".  My shares are still there and I can copy from my NAS to my computer.  

 

My firmware is 6.10.1

The system has 23.64 TB with 4.56TB available. With X-Raid on.

There is Three USB drives connected and I can write files to all three USB Drives,

 

My Computer is running Windows 10 Pro

 

 

  • Hi PC_Dock,

     

    It looks like a file system corruption happened in your volume. I see a lot of these messages in kernel.log:

     

    Sep 05 15:26:01 PC-DOC-NAS kernel: BTRFS error (device md126): bad tree block start 12307480573248903287 21371832008704

    It is best to do a factory default then restore from backup when you get these errors. If you are not able to backup all your files, you may contact NETGEAR Support for data recovery (https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service).

    If you don't have a backup of the NAS  you should make one right away (or update it).

     

    Log into the admin web ui of the NAS and see if the volume is set to read-only.  If it is, that usually means the NAS has detected file system corruption.  You can download the log zip file and look in there for analysis (or ask one of the mods to review it).  But the backup is the first priority.

      That does seem to be the issue.  I see that the volume is set to read only and there is a couple of shares that I am not able to open that show undefined error code.

       

      I tried to attach my sipped log files but the system would only allow jpg,gif,png,pdf files

        You shouldn't post them publicly anyway.

         

        Instead put them into cloud storage (google drive, dropbox, etc), and send a link via private message to one of the mods ( JohnCM_S or Marc_V ) asking them to analyze them for you.  You send a PM via the envelope icon in the upper right of the forum page.

        Back up what you can though.
