  • OMV on Proxmox 7.4-3 dont read more than 1GB of RAM, assigned 16GB

    I have tried OMV on Proxmox out of interest and have found 2 GB has been more than enough. Depends what you are doing of course. My standalone server has 16 GB rarely uses more than 2 GB, this is streaming four videos on Jellyfin. I only have 16 GB (2 x 8 GB) to speed up dual channel RAM for transcoding. I suspect there is nothing wrong at your end.


    Edit - just looked at your first pic more closely - now not so sure. But here's my standalone system like yours not as expected.


    Code
    root@omv:~# free -m
               total        used        free      shared  buff/cache   available

  • MergeFS and Remote Mount

    Wouldn't advise a mergerFS pool like this, better to make two separate pools. Reason I say this is that I have had two mishaps with a similar approach. First time a USB external drive from the pool failed to mount, I was away for the weekend, the system was unusable. Not too hard to fix.

    Second time a SATA card with two drives on it failed to start on time due to change in BIOS power saving settings, the drives therefore not available for the pool in time. Big headache to fix as the problem was obscure as those two drives were present. Just my experience.

  • Poweroff or Standby/Sleep

    I have never been able to get RTC to wake the system (hardware specs below) but there is a BIOS setting to wake at specified time. Alternatively set up a very low power always on device (Pi or similar) with Ubuntu and make a cron job:


    55 13 * * SUN /usr/bin/wakeonlan MAC address of OMV


    This wake OMV at 13:55 on Sunday.

  • Securing OMV with Tailscale cert

    I have done this by getting Tailscale to obtain an SSL cert and key and loaded them through the OMV workbench page. Https works fine with the Tailscale MagicDNS address of the form (for example):


    https://omv.chicken-duck.ts.net

    I am looking at automating this as the certs will expire. I see the key has been renamed by OMV to openmediavault-long-string.key. Is this name significant? If I get a new key and rename it to this or the default openmediavault.key (which I think is the old self signed cert) will it work? Or will I have to manually reload the new cert and key through workbench?

  • Mergerfs lost pool

    Thanks but I couldn't reproduce what I have done and a lot of it is down to my mistakes I think, so I couldn't submit a coherent bug report. What I think set this off was that I cleaned dust out of the device, changed the BIOS setting for maximum power saving. A side effect of this was that two SATA drives on a PCIE card were slow to activate so the pool didn't load. If I had spotted this at the beginning it would have saved a lot of grief.

  • Mergerfs lost pool

    Spent hours trying to fix this today. Best I have done is remove mergerfs, remove entries referring to mergerfs from omv config, delete the systemd unit. Reinstall and recreate the pool and all seem back to normal but -


    Shares are in default locations e.g. Movies is /Movies and not /mergerfs/pool/Movies. Despite this /srv/mergerfs/pool/Movies has the movies. So I can play in Jellyfin.


    I can't move the shares as I get error: Failed to execute Xpath query.....


    The way the system is it does not survive a reboot.


    Close to doing full reinstall - any way to avoid?

    Attempted manual pool restart:

    Pool isn't mounting again. This si the result of the above command:


  • Mergerfs lost pool

    Yes I tried the restart pool it did nothing. I suspect now having thought more that I knocked a drive connection when cleaning dust from the case hence the problem. But reconnecting all the drives and rebooting didn't fix it.


    Anyway more or less back to where I was, thanks all for the input.

  • Mergerfs lost pool

    # omv-showkey mntent produces a lengthy output which contains some references to the old pool.


    # om-showkey mergerfs produces:


    Which looks OK.


    I'll sleep on it - I think the way forward is to delete the references to old pool and shares from the OMV config file.


    It's all working again so the heat is off.

  • Mergerfs lost pool

    Thanks for the tip wasn't aware of that.


    I am making progress, I have created a new pool called pool2. I can't add my shares to the pool2 as they appear to be in the pool I lost.


    I have deleted NFS, SMB, rsync references. How can I remove the old pool?


    Would removing this section of the omv config file do it? Don't want to mess things up more than I have.



  • Mergerfs lost pool

    I have a six drive pool that stopped loading for unclear reasons. All members of the pool seem ok. To try to fix I deleted the pool thinking I could recreate it, but this is not working. Uninstall and reinstall the plugin did not help.


    When I try to recreate the pool I get the 500 error.


    Any way to recover from this?
