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

  • Hi Community, good day and nice to meet you.

    I need some help with my setup, unfortunately i didnt found a solution on internet.

    I have an OMV 5 running in my proxmox server. this vm have 16GB od ram assigned but can only read and use 1GB.

    I tried to adjust this but was not able. how can i fix this?

    VM profile

    VM settings:

    I already tried a lot of settings, adjusts and nothing worked.

    Thanks in advance.

  • 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.

  • Thanks for your time johnvick. I was able to solve it yesterday morning by installing proxmox kernel on it, change hotplug options on vm profile, shutdown and start again.

    Now i am able to use 16GB on mt OMV 5. This storage is used to mount a zfs pool from an old and retired FreeNAS. this zfs pool is nfs mounted on an Emby server where i host my own media, working smooth now with 4k media using HDR..

    Thanks once again.
