Moved existing RAID to new OMV installation - not shareable

  • Hi,


    I moved a raid system from an old OMV (2.x) installation to a new fresh instalaltion.
    After installing the OMV system I reinstalled all my 5 RAID drives.
    mdadm found the RAID again and I updated the config file:


    cat /etc/mdadm/mdadm.conf
    ...
    # definitions of existing MD arrays
    ARRAY /dev/md/raidvolume metadata=1.2 name=Flex:raidvolume UUID=ac79d13f:c4cc963d:784d2961:931c8716

    blkid
    /dev/sda: UUID="ac79d13f-c4cc-963d-784d-2961931c8716" UUID_SUB="c6767d28-dc49-d138-61d7-7927fe5aed4b" LABEL="Flex:raidvolume" TYPE="linux_raid_member"
    /dev/sdd: UUID="ac79d13f-c4cc-963d-784d-2961931c8716" UUID_SUB="4d926477-6b82-64ab-f9fb-dc6adf4d63b8" LABEL="Flex:raidvolume" TYPE="linux_raid_member"
    /dev/sdb: UUID="ac79d13f-c4cc-963d-784d-2961931c8716" UUID_SUB="d9fec3d9-dcaf-5e4a-9f80-031711610feb" LABEL="Flex:raidvolume" TYPE="linux_raid_member"
    /dev/sdf: UUID="ac79d13f-c4cc-963d-784d-2961931c8716" UUID_SUB="ab30c75e-cc09-b881-d185-aee0f66f7ae4" LABEL="Flex:raidvolume" TYPE="linux_raid_member"
    /dev/sdc: UUID="ac79d13f-c4cc-963d-784d-2961931c8716" UUID_SUB="b96fcdf1-1f89-39d0-45fa-97a7c3137560" LABEL="Flex:raidvolume" TYPE="linux_raid_member"
    /dev/sde1: UUID="655cfcf0-1f0a-4541-8fcc-b8c313345dab" TYPE="ext4" PARTUUID="b42659d4-01"
    /dev/sde5: UUID="baa07cc9-088f-4920-97b8-e239abc2338f" TYPE="swap" PARTUUID="b42659d4-05"
    /dev/md127p1: UUID="5b6d66b2-d41e-42df-8ddc-3702a7695ad0" TYPE="crypto_LUKS" PARTLABEL="storage" PARTUUID="66d16568-e961-4875-a688-04dec86274c6"
    /dev/mapper/storage: UUID="e36baf9f-146d-4959-9ff1-a900060babd4" TYPE="ext4"
    /dev/md127: PTUUID="9423ac42-9337-4ec0-96a9-e9fa290140cb" PTTYPE="gpt"


    Then I installed cryptsetup on the system and mounted the RAID-Partition:


    cat /etc/crypttab
    # <target name> <source device> <key file> <options>
    storage UUID=5b6d66b2-d41e-42df-8ddc-3702a7695ad0 *keyfile* luks

    mount
    ...
    /dev/mapper/storage on /media/storage type ext4 (rw,noexec,relatime,stripe=512,data=ordered,jqfmt=vfsv0,usrjquota=aquota.user,grpjquota=aquota.group)


    I also tried to setup fstab as it was on the old system:


    cat /etc/fstab
    ...
    tmpfs /tmp tmpfs defaults 0 0
    # >>> [openmediavault]
    UUID=e36baf9f-146d-4959-9ff1-a900060babd4 /media/storage ext4 defaults,nofail,acl,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 0 2
    # <<< [openmediavault]


    The GUI only shows the filesystem with a dummy device /dev/dm-0 (I already changed the fstab to mount this pointer)
    But I cannot access the filesystem. There are no device options:
    How can I add the device to the Filesystem tab or can get access to the filesystem?
    I do not see a way to reset the array.
    Thanks a lot for any kind of support!
