NAS with ReadyOS 6.9.3 hangs with message btrfs_set_root_node+35 in LCD screen.

Hi.

 

I own two ReadyNAS, one for active usage and one for backup. The backup device shots down after the backup process and starts shortly before. In the last time sometimes it hangs on the shut down. Yesterday the LCD screen showed btrfs_set_root_node+35. I could shutdown the NAS holding the powerbutton only. My primary device is active 24h a day and does not have any problems. Perhaps somebody know the issue for such problems.

 

Regards,

Nils

    Hi augur,

     

    It will be best to replace disk 2. Since the data volume is still mounted, replacing the disk could be all that is needed.

    Hi augur,

     

    Can you download the system logs of the NAS that is having the issue? If yes, you may provide it to us. Please check this link on how you can send it.

        Hi augur,

         

        It appears that disk 2 has a current pending sector count of 1. Based on the smart_history.log, it just happened recently.
