Aall shares have disappered from the web UI

Annoyingly, my system restarted itself unexpectedly at around 10pm last night and when it came back up, all the shares (except for home folders) had disappeared from the shares tab of the web UI, although the data was clearly there as I could browse the shares from my PC (and even run a DR backup from the backup tab!)

 

This seems similar to this (closed) thread:

https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/All-files-have-quot-disappeared-quot/m-p/1653278

 

Luckily, I had taken a configuration backup a week or so previously - and restoring that (and then rebooting) seemed to restore things.

 

Any log files I can check for a possible cause of the unexpected restart, or indeed confirm that my data is still intact?

    df -h is showing /dev/md0 partition is 36% (of 4G) used but

    btrfs file usage // shows only 330 MB unallocated (of 4GB).

     


    Run a balance

     

    btrfs balance //

    That should increase the unallocated space.

     

    FWIW, running out of unallocated space could have triggered your problem.

    What model NAS do you have, and what firmware is it running?

        Do you have a backup of the files?

         

        I'd start by looking in 

        • dmesg.log
        • status.log
        • readynasd.log

        and then look in 

        • system.log
        • kernel.log
        • systemd-journal.log

        Maybe also check the unallocated space in the OS partition using ssh.  btrfs file usage //
