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...

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...
