    ZFS RAM usage more than 90% of the system

    Hello, We've upgraded our PVE cluster of ndoes from 5.4 to 6.2 few weeks ago, we also upgraded our ZFS pool to the version 0.8.4. We also added an iSCSI storage (FreeNAS) which hosts now most of the storage. I'm now seeing that the ZFS cache is like eating a little bit too much of RAM (this is...

Hi, I am running 6.2-4 and one ubuntu 20.04 server vm. Pve reports that the vm uses 775mib of ram on idle, but it reports that the node is at 3.65...

    VMs take more RAM than they should, breaks Ressource calculation

    Memory issues

    I have been trying to figure this one out by my self but I think I need some help with translation. One of nested Proxmox servers that has 4 LXC servers running (each using ~1G RAM) claims that it is using 14G out of 16G. What is the rest of the memory being used? root@vh0:~# cat /proc/meminfo...

    RAM usage well exceeds VM assignment

    Hi, Lately I realized that the RAM usage on PVE exceed the amount I allocated for the VMs. For example, now I am running a single VM and 4 GB RAM has been allocated to it, but the summary of the host says 15GB+ RAM has been used. I am running PVE 6 with 32 GB RAM and a ZFS storage pool (1.8 TB...

    Hi everyone, First of, I am well aware of the famous "Linux ate my RAM" page and I post here because my issue makes no sense. I am also aware of the usual RAM requirements of 1GB per TB or storage for ZFS, but again, seems a bit odd in my situation. I have 5 VMs on my server, of which only...
