    Hello

    Not as far as I remember. Server was off during holidays because of heat. I vaguely remember trying to mount the volume of the other NAS, but remote config is empty.


    No manual change currently. I search for the ID mentioned in my mounts and fstab, no luck.

    Hello


    Just restarted my server 6.8. After running a system update, I have a yellow block telling "Configuration changes waiting".

    When I apply the command there, I get the following error


    Code
    openmediavault.config.database.DatabaseQueryNotFoundException: No such object: //system/fstab/mntent[uuid='13118aad-7d2c-4c12-963f-b40e2b8a3b6c']

    All my disks are OK.

    I don't know where to look to remove missing uuid from configuration

    That was it.


    Code
    # mdadm /dev/md0 --add /dev/md127
    mdadm: re-added /dev/md127

    That looked good



    And now State is clean.


    Back to business, now :)


    geaves: your insights helped, thank you !

    Hello geaves

    , but the output, as I said does not suggest that.



    Did you manage to test it as you wish ?

    Going back from holidays., I booted it up, and issue rose again.



    and examining both volumes lead to:



    md127 does not know it's not active in the raid1.

    mdadm --stop and --assemble seems dangerous and overkill to me.
    Maybe I can try --re-add ?


    Backup is done, ready to test :)

    Hello,


    I have this config in my NAS:


    • OMV 5.6.22 on 32GB USB stick
    • 2 SSD of ~ 230GB in RAID0
    • One RAID1 array with a 3rd SSD of ~ 470GB and the RAID0 array


    There was a power loss, but the UPS kept it cool. I triggered the shutdown through power button, and had the beep to confirm the soft shutdown triggered.

    Once started, I received an email with subject "DegradedArray event on /dev/md0:grange"




    /dev/md0 is still mounted and readable

    It seems I didn't loose data, though I'm using only ~ 40GB.


    IIUC, from mdstat:

    • md127 is missing from md0
    • sdb is "disabled" from md127


    I don't know what to do to restore a clean state.



    SMART tests look OK:

    I don't know why, but BIOS is not able to switch to more than one HDD.

    As I said in my previous message, you need to tell it which one hosts the boot sector. It assumes it is the first one by default which is a good behaviour.

    but we, geeks, are not using any defaults, right ? :D

    I'll be rebooting sometime this weekend. I'll try to grab some screens to show how the bios is set. I've messed around with various boot order combinations. Also, the drive is direct connected to the first SATA port, not via usb.


    Thanks!

    In my BIOS, I can switch the USB one but also the 3 connected SATA.


    Let's see how it goes :)

    Glad it's fixed.. sorry, I shouldn't be posting at 0130hrs on very little sleep.. I completely missed that.. :). Had I noticed the one disk had data on it the answer would have been more obvious.


    Glad you got it going.

    Well, I cleared the disks with fdisk, but it was not enough for OMV, I guess.

    USB drives?

    No. As you can see on the screenshot, the show as ATA (Serial ATA, actually).


    If the disks are not totally clean, then they are not listed. So use the 'Wipe' option in the disks page.

    Thanks for the notice. I didn't get at first the purpose of this button. It is now clear :)

    That worked.



    An OMV journey begins :)

    Hello,


    I installed OMV 5.5.22-1 today.


    I have 4 disks:

    500, 250, 250 for data

    32GB for the system



    The 250GB were used disks, so I went to filesystems and cleaned them:


    forum.openmediavault.org/wsc/index.php?attachment/18302/


    But when I try to create my mirror, I only see the 500GB disk:



    I rebooted after cleaning the filesystems, but issue is still there.


    I can't see what I did wrong.


    Thanks

    You can put these 3 drives in a btrfs raid1 array which will give you a total storage of 512 GB. There is a recent conversation about this at:


    RE: Any roadblocks I should be aware of prior to trying to partition the drive(s) & setup a btrfs on seperate partition(s) of individual drives?

    This is one way, but reading the thread, all BTRFS stuff has to go through CLI. I'm not afraid, but I would prefer a GUI-compatible solution.


    I'm thinking out loud:
    - Can I use mergerfs on the two 256 then create a RAID1 with this and the 512GB disk ?

    Hello,


    I just installed my leftover system with OMV 5.5.11 on a 32GB stick.

    My initial target was a RAID1 with two 512GB disks. I ended up with 3 SSD : 256 + 256 + 512


    What would be the best way to assemble my disks to reach my goal ?


    Thanks for your help
