Issue with raid/file system after Upgrade from 3 to 4

  • After upgrading from OMV3 to OMV 4 my raid array was missing. I feared the worst and thought that my data was lost. But after having looked at (probably) every entry in this forum about raid I was at least able to somehow get the array mounted back and have access to my files again, but the configuration in OMV is screwed up

    When I go to tab file systems (attached)...When I want to edit a shared folder for instance (attached)

    The files I messed with I guess are the obvious ones (attached).

    I have tried everything I can on my own...can anybody help me please?



  • Here's the result:

    Personalities : [raid6] [raid5] [raid4] [linear] [multipath] [raid0] [raid1] [raid10]
    md0 : active raid5 sdf[3] sdc[0] sdd[1] sdg[4] sde[2]
    15627548672 blocks super 1.2 level 5, 512k chunk, algorithm 2 [5/5] [UUUUU]

    unused devices: <none>

  • There are other users with the same problem. Seems to be that some installations have a problem with MDADM RAIDs after switching from Debian 8 to Debian 9. In most cases the users have reinstalled OMV3, created a backup of the RAID data, installed OMV4, erased the old RAID and recreated it again. The problem is that the Debian 9 kernel or userland can't indentify the filesystem on the RAID.

  • Ufff, that sounds like a lot of cumbersome work... ;(;( ...and I don't have enough spare HD space to backup my entire raid...

    so in essence...backup data, delete raid, freshly install OMV4, create raid, restore data...I have to send my wife on a cruise to have enough time to get this done :D
