ram utilization

"ZFS ate half of my RAM." - :eek: That's pretty much how it started. Diving deeper to this subject it appeared that it's very common problem. Here are few topics on this forum that I read to understand what's going with ram: "Disable ZFS ARC or limiting it" "zfs_arc_max does not seem to work"...

Hi everyone, I have a server with 2 x 1TB storage - raid 1, 64GB of ram, AMD 5600G CPU. I created 1 VM where i use cPanel with 16 GB ram, and i can see that the PVE host jumped up to 80% (almost 50GB) RAM usage. What can cause this? I went through the forum posts and i see this can be just...

Dear all I have an issue when copying large chunks of data from one virtual machine to another. The RAMs on the source and target machines are filling-up until, disk I/O increases until the whole host system freezes. Swapping however seems to be decent. The hosts are on different SATA discs...

Hello, recently I noticed a problem with ZFS and creating compressed backups (ZST compression) on the latest Proxmox VE 6.3-6. Every time I create a backup, my entire RAM + some SWAP (64 GB DDR4 + 32 GB SWAP) quickly fill up. This RAM won't (!) free up after the process has finished and will...

Hi, I think the GUI shows the wrong RAM utilization for my Win10 VM (v1909). Proxmox 6.3 is updated to the latest version and I installed the kvm guest agent. Right after starting the VM the GUI shows a RAM utilization of 90%+ but Windows shows me a way lower utilization: KSM is enabled...
