    • Problem with RAID 5 under OMV 5.0.5

      Dear all,

      I freshly installed OMV 5.05 (was having debian Buster before but decided to go for a NAS solution this time).
      I am having trouble setuping my RAID 5, I wiped my 3x HDD (6 TB each) and then create the RAID 5.
      However in the RAID management I was expecting to see only 1 unit md0 but I see 4 (the main 1 plus 3 small md1, md2 and md3). I guess it might be because I clicked on apply before assembling was completed. Hence maybe it incorrectly wrote inside the mdadm.conf. But I am not 100% sure.
      Anyway, now my RAID 5 is created but not functioning because I can't create a file system on it. I also tried to delete it and start over, but it fails. Hence, I am planning to do it manually via ssh. It is Debian based, so I imagine it should be ok if I do it manually but I am not sure how much OMV customized the Debian base. Do you think it is feasible folloiwng a Debian tutorial? Any advice?

      Thank you in advance for your help.
    • OMV displays what is in /proc/mdstat. I assume you need to destroy the other devices, too.

      I must not fear.
      Fear is the mind-killer.
      Fear is the little-death that brings total obliteration.
      I will face my fear.
      I will permit it to pass over me and through me.
      And when it has gone past I will turn the inner eye to see its path.
      Where the fear has gone there will be nothing.
      Only I will remain.

    • And yes, you can create the RAID via CLI and OMV should recognise this (because it simply parses /proc/mdstat) and display it in the UI. There is no magic done by OMV.

    • Don't forget to update the packages first before starting over. The ISO is not up-to-date, but updating a system after installation is general procedure, right? ;)

      of course, this is the first thing I tried but it did not work either...I had some error message and I had not a lot of time to investigate. Tonight, I will reboot my server and hopefully that will work. Otherwise I will try a first update / upgrade also from the CLI.
