      Is it advisable to down grade to an earlier kernel as the issue started with 4.13?
      This should workaround the problem according to those bug reports that took a deeper look. But of course it would be better if the problem would be identified and solved with recent kernel versions so the fix can be backported to 4.13 later.

      Threads/reports to watch:
      Besides that I've no idea whether a workaround in OMV is possible (not relying on blkid output -- but if I understood the bug reports correctly the problem is more severe than just cosmetical issues with one tool)
    • Just upgraded last night from a stable 3.x build (running for a LONG time with no issues) to 4.1.0.1).

      As others have stated - my md0 partition is not mounted or recognized.

      It is comprised of Qty 4 - WDC-WD30EFRX-68E drives.

      Has anyone come up with a fix or this???

      The information appears to still be there - and I do not want to risk losing everything - - any thoughts?

    • You have a backup right? I would try reinstall with the drives in place. Be sure to let the install reboot on it's own, don't force it. Seems there are scripts running that if they don't finish can cause random problems.

      If you don't have space to do a backup and it is raid 1, you should be able to do the install with only one drive in the machine. Once it is up and working you can add the other drive back.

      Good luck
      If you make it idiot proof, somebody will build a better idiot.
    • It is Raid 5 with 4 drives. I do have a backup (I have this sync to another NAS for most of the files - but not all - - I know, bad planning on my part)

      I reinstalled with version 3.x - Array was still there - re-created SMB shares and added them as shared folders - and can access everything.

      Thanks
