File system not mounted and missing

  • After almost a year of regular operation, after a normal update, one of the disks is no longer mounted, not even on reboot. In Storage -> Disks is regularly listed (device /dev/sda). In Storage -> File Systems is listed, but:


    Device (s)
    /dev/disk/by-label/WD_RED1_4TB (instead of /dev/sda1)


    Label
    _empty_ (instead of WD_RED1_4TB)


    Filesystem Type
    ext4


    Total
    n/a


    Available
    n/a


    Used
    n/a


    Mounted
    No


    referenced
    Yes


    Status
    Missing


    The Mount button cannot be used because it is grayed out.


    What do you advise me to do?


    I'm using OMV 4.1.26-1 (Arrakis), Linux Kernel 4.19.0-0.bpo.6-amd64, SMP Debian 4.19.37-5+deb10u2~bpo9+1 (2019-08-16) x86_64.


    Thank you so much for your help.

  • This is exactly the same error pattern as in this thread: Disk lost after power outage, post #6.
    Did you change any of the physical disk properties in the past?

    OMV 3.0.100 (Gray style)

  • I finally solved. First of all the disk was in perfect condition and I had never made any changes to the physical disk properties.


    Checking the boot logs seemed to be a dependency error for the sharedfolders.


    I have installed the "resetperms" plugin which allows you to see the list of shared folders in use.


    With regards to the disk in question, I deleted all the shares from the various services (such as ftp, smb etc.) and finally I deleted the Shared Folders for the disk.


    I added the Shared Folders for the disk in question again, naming them in the same way as before.


    I restarted the applications involved, in my case Plex Media Server installed in a docker.


    Everything was finally back to working properly. Made a reboot for security, all perfect, the log was error free.


    We can close the thread. :D
