    Is there anything which helps to manage multiple OMV installations? I have 3 computers, one is working as a NAS, two another works like normal servers. All three have kubernetes deployed, so their configuration (apart from Nas functions) should be the same.

    Normally I would use ansible, but OMV use salt which seems to be the same thing. Also OMV doesn't like changes invoked outside UI.

    I would like to have one common UI, and just switch which computer I manage.

    Even better would be to have one common console which makes the same things on all computers, like updating packages.

    Is there anything which can help me?

    I've recreated GPT partition table, partition type changed from zfs_member to atari(?). Then I've created filesystem using mkfs.ext4 - it complained about "atari" stuff but finally created filesystem and now it's visible in OMV.

    Unfortunately SMART is still not parsed.

    Maybe you're right

    I've recreated partition but it still shows :

    /dev/sda: TYPE="zfs_member" PTUUID="c3264049-2b83-4d76-b04b-07948b43aac7" PTTYPE="gpt"
    what does this TYPE mean and how to set it correctly? Using parted I've just create primary partition from command line, no filesystem yet:

    (parted) mkpart primary
    File system type? [ext2]? ext4
    Start? 0
    End? 3001GB
    Warning: The resulting partition is not properly aligned for best performance.
    Ignore/Cancel? I
    (parted) quit
    Information: You may need to update /etc/fstab.

    Should I do that in different way?

    I don't understand. This disk was previously ZFS disk. I've just put it into OMV. It didn't see any filesystem on this disk, so I just pressed "create" button, it offered me this disk, then I accepted. It created filesystem on it, it took some times. During this process I saw filesystem, but when the window is closed - it disappeared.

    Maybe there's unsupported partition type or what? I'll try to remove whole partition from this disk to make it totally empty - let's see if it helps.

    oh, I didn't notice this hash :D

    root@silver:~# cat /proc/partitions
    major minor #blocks name
    8 16 117220824 sdb
    8 17 113110016 sdb1
    8 18 1 sdb2
    8 21 4108288 sdb5
    8 0 2930266584 sda
    8 1 2930265543 sda1

    I've recreated partition on sda again, and during creation I see this partition on the list (in the background, under popup window). Creating filesystem takes some time, and when it ends and I close a popup window, partition disappears from list.

    I'm attaching output of all commands.

    I've freshly installed OMV on Pegatron motherboard with Celeron 847 (quite old and exotic but works). It's mini ITX form factor, but contains PCIex slot. I've put there LSI SAS controller, which is flashed to IT mode.

    I boot from SSD drive attached directly to motherboard SATA port. Everything works like expected: all partitions on disk are visible, SMART fully works.

    I've attached also SAS disk, HGST 7200 RPM, via LSI controller. OMV sees this disk but:

    - SMART status, when enabled, is not green, just grey

    - SMART information sees only serial number in first three tabs, everything else is empty

    - Extended information is there, I'll attach it

    But it's not the end of story.

    I've created partition on this disk. It was created successfully, it's visible in command line via fdisk, but OMV doesn't see it (despite it've created it):


    1. is LSI SAS controller fully supported by OMV?

    2. Why OMV doesn't see partition it has just created?

    3. Why SMART is not fully visible in tabs?

    4. Is this disk simply a trash?

    Attached SMART extended information:

    any news about it? I'm fan of Ansible, but I see OMV already use similar salt solution. But how to use it if, for example, I have multiple OMV computers? I'd like to manage them in one centralised point, the best would be sth like roles in Ansible, stored in GIT. So if sth bad happens, I can clone GIT repo on any computer, install Ansible on this computer, install OMV, then run playbook and my OMV is in desired state

    I'm generally aware what's mergerfs. The thing I'm not sure is which paths should I put when mounting. Omv mounts my disks itself. I expected mergerfs plugin to give me choice from this mounts, but it asks me for paths and I'm not sure which paths should I use. Those from /srv ?

    I want to use mergerfs. I've installed plugin from extras, but I'm not sure how to correctly use it. Is there some blog or guide I could read to see an example usage?
