memory usage

Hi there. Some time ago, I read that if someone wants better monitoring, then they need to set up specialized monitoring software and not rely on PVE graphs. Nevertheless, I do believe that ZFS users without monitoring software (like me) could benefit from showing ARC size in a memory usage...

Hey all, Relatively new installation of 3 node cluster, running CEPH for storage. over the course of about two weeks one of the nodes went from ~40GB of ram used to 265. Moved the VM's around so that we could reboot the node, and it went back to the "normal" usage (with the machines on) of...

Hi everyone First off, I do appreciate that measuring memory usage on modern OSs is an inherently tricky topic and there's not really one definitive "correct" answer to "how much free memory I have", given all the intricacies involving virtual memory, filesystem caching, etc. That being said...

I have several nodes running Ubuntu 18 or 20 as guest OS. They have 32 GB allocated memory, but show on the web monitor summary as using less than one of percent of allocated RAM. The Memory usage shows pale green 32 Gi, but reports RAM usage (dark green ) about 140 MiB. On the guest OS I...

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...

Hello There, lately, I have configured a 2 node proxmox cluster (Raspberry Pi as q device) each node runs couple of lxc containers however the memory utilization on node 2 is drastically high. any idea how to get and fix that high memory utilization top command from node

Hi everyone, I am new to Proxmox and I have been searching around on how to solve this issue. I have learned that ZFS requires ECC memory, I have been using ZFS on Ubuntu server for a year now with standard DDR4. I ordered an Epyc 7402 and Supermicro H12SSL-i, I will buy ECC memory now that I...

Hello Everyone, A few days ago I installed proxmox on an old Lenovo laptop (i5, 3rd gen, 8 GB ram, 240 GB SSD) and installed Openmediavault 6 as a guest VM, gave it 2 cores and 4 GBs of ram, and set up a simple SMB share with an external HDD passed through to the OMV VM. Since I'm new to...
