  2. Backup RAM overload

    Ich speichere meine Backups täglich auf eine extern eingebundene NAS. Das Problem ist, dass jedes mal, wenn meine Backups gemacht werden meine RAM usage in die Höhe schießt.

  6. VM Crashing - Out of Memory

    Hi, I have a VM that crashes every 10 days or so. I initially attributed the issue to something in Windows Server 2012R2. I wrote a little script to check status on this VM every 30 seconds, and restart it (and email me) if it crashes. The script just uses this: qm list|grep $VM_NAME |grep...
  7. Anormal ram usage

    Hello, I just installed my Proxmox server. I have a strange phenomenon. The installation is brand new, I have no VMs started and I have constant ram usage at 18Go. Would this be normal behavior with ZFS using available ram to cache? If so, is it quite disturbing because we do not know how to...

    Hi Am trying out Proxmox+ZFS on the same machine. Am new to ZFS. Am monitoring my server with Zabbix and my memory usage is 90%.

  10. Trying to understand LXC RAM and SWAP allocation

    I have a workstation with 256 GB RAM, and by default the host has only 8 GB SWAP. With the two LXCs I have, as they can potentially use a lot of RAM, I committed 192 GB RAM and 64 GB SWAP to both. My question is, in a situation where both LXC reaches a high usage and they consume more than 256...

  16. Limit RAM used by ZFS?

    My 64GB RAM machine with ZFS seems to stabilise at 80% memory usage all the time for the root proxmox host. (Proxmox 6.2.4) I have several VMs running on top of it, all of them using no more than 20GB of RAM, so I suspect all the RAM usage is by ZFS on the root host. I've read several posts...
  17. VM Using RAM Allocated, Even when not in the VM

    Hello Everyone, I am wondering why does proxmox use the ram allocated the VM, even if the VM isn't using it? and is there any way to stop this? I use Windows Server 2019, Balooning is active and working, but in htop it shows the one VM using 32GB RAM when it's only really using 6GB, also I...
