reccurent RAID issue after reboot

  • Hi all,


    I had to shutdown my OMV before an power intervention at my place.

    I made a clean shutdown of course


    After a reboot I was not able to see my RAID 5 on the OMV interface


    After a :

    $ mdadm --stop /dev/md0


    then a :

    $mdadm --assemble --force --verbose /dev/md0


    I was able to get my RAID back. At first the sde disk was not mounting on the Raid group

    To be sure I made a reboot then I got back to the same issue (no RAID displayed)

    after the same 2 command that is now ths sda disk that is not mountig in the raid


    Here are the required commands and thir output :



    OMV : 5.5.18-1

    kernel : 5.5.9.0-0.bpo.2-amd64


    Let me know if more detail is needed


    Thanks in advance

    Changed the title of the thread from “reccuring RAID issue after reboot” to “reccurent RAID issue after reboot”.
  • When specifying assemble using this -> mdadm --assemble --force --verbose /dev/md0 add /dev/sd[drive letters in the array]


    This -> mdadm: failed to add /dev/sda to /dev/md0: Invalid argument but it doesn't state what that is ?(


    Storage -> Disks select sda on the menu click wipe and then short, when complete; Raid Management -> select the raid, on the menu click recover a dialog should display sda select it and it will be added to the array, the raid should rebuild. Come back if there any errors, but it should be OK.

    Raid is not a backup! Would you go skydiving without a parachute?

  • Thanks,


    It helps. I erased sda then readd it to the raid

    It is rebuilding


    however I hope it won't reappear at next reboot
