Raid is not conectet to OMV

1. offizieller Beitrag

    Hi i have a OMV with 4 Raid 1


    md0pX is System

    md126 and md127 are to store Data


    aditional there is a md1 but it in not avalible i think there is an mismatch by the naming i have 2 of openmediavault:1







    What is hapend and how can i fix this?

    Now the Raid is still Mounted but the filesystem is still missing.

    I think the problem are the name in The RAID both have the name "openmediavault:1"

    But how can i rename this.
    It seems to be the share folder "AUDIO" on the missing filesystem ist aktiv


    Somebody a idea where i have to search for a fix?

    I've got the same problem after installing a new version of OMV. But also I noticed something very interesting. Yesterday when I was trying to solve a problem it was a B letter for my disk with OS according to lsblk. Today the letter is C. When I installed OMV for a first time three yeas ago the letter was A.

    Got it, thanks.
    But my problem still exists. My linear RAID is not visible in web GUI and I can't do anything. However all disk are visible in DISKS and SMART shows GOOD for each one.
    The only place where I can see it is Storage/Software RAID. In Storage/Fle system there is only OMV disk

    This is normal. The kernel assigns the device names according to first come first serve. That's the reason why OMV is using and forcing predictable device names to do not run into problems with changing device names.

    Thanks for your replies, votdev!
    The system is still 6 not the 7


    root@******:~# cat /proc/mdstat

    Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]

    md0 : active linear sda[2] sdd[3] sdc[0] sdb[1]

    10743785952 blocks super 1.2 0k rounding


    unused devices: <none>

    I upgraded the system to 7 and installed openvediavault-md plugin. Unfortunately the situation is just the same. RAID is visible only in Storage/Multiple devices. That's all.

    By the way, I can't see OMV-md plugin anywhere

    cat /proc/mdstat


    blkid


    In This Output i MISSING "md1"


    Code
    root@openmediavault:/# blkid | grep md1
/dev/md127: UUID="a13b9b2b-2ab7-4b6d-9518-7a1a4aab7460" BLOCK_SIZE="4096" TYPE="ext4"

root@openmediavault:/# blkid | grep md1:
root@openmediavault:/#




    fdisk -l | grep "Disk "

    cat /etc/mdadm/mdadm.conf




    mdadm --detail --scan --verbose


    Code
    root@openmediavault:/# mdadm --detail --scan --verbose
ARRAY /dev/md/openmediavault:1 level=raid1 num-devices=2 metadata=1.2 name=openmediavault:1 UUID=e8813293:c748ef06:59ba08ab:abec093c   devices=/dev/sdb,/dev/sde

    In this Output are two times "openmediavault:1" with the same UUID, but i dont know why and i dont know how to change this?


    Code
    root@openmediavault:/# mdadm --detail --scan --verbose | grep openmediavault:1
ARRAY /dev/md/openmediavault:1 level=raid1 num-devices=2 metadata=1.2 name=openmediavault:1 UUID=e8813293:c748ef06:59ba08ab:abec093c

root@openmediavault:/# mdadm --detail --scan --verbose | grep openmediavault:2
root@openmediavault:/#


    I tried to understand the Config.xml

    but without succes :/
