Error No filesystem backend exists for ''.

  • Disks are there and accessible but filesystem in OMV GUI gives the following error:




    Error
    No filesystem backend exists for ''.

    I get the same error when I go to shared folders


    Any help here would be appreciated
    Thanks

  • What filesystem? Is the filesystem on a working raid array?

    EXT4 not in a raid

  • I have only recently re-installed OMV and have remounted my drives. (Done this a fair few time before)


    The only thing I can think of is that I removed the noexec from each of the drives and maybe something happened when I did that.


    Going to be moving to new hardware soon and will be flattening everything.


    Thanks for taking the time to help

  • I'm sorry, i have really no idea what is going on here. The database looks valid and the output of blkid which is parsed looks also good.


    There is only one thing im wondering. The error message tells that there is an invalid mount point configuration, but you posted a list of four valid mount points.
