I have a cluster with 4 servers, and after the upgrade version from pmox 8 to pmox 9, one of my servers had a problem on the middle of upgrade, on the shell i clicked on a vm, and break the upgrade in the final, after seeing on the forum, i recovered the proxmox and finished the upgrade, after that, the server started to loose performance.
In this server have 2 VMs, 1 with 2 sockets, 24 cores; 440GB RAM; and 500G SSD, the other have 1 socket, 14 core; 48GB RAM; and 60GB SSD.
The first VM is crashing randomly, doesn't show the sumary and sometimes i can't access from the console, it stay connecting infinitly.

OBS: the server have 02x E5-2680v4 2.4GHz 28C/56T; 16x 32GB = 512GB; 02x 1TB SSD - Raid1+0, the medium use is on the print i attached. The other servers are working normaly, with higher workloads.



I have a cluster with 4 servers, and after upgrading from Proxmox 8 to Proxmox 9, one of the servers experienced a problem during the upgrade. In the terminal, I clicked on a VM, and the upgrade was interrupted in the final phase. After consulting the forum, I recovered Proxmox and completed the upgrade. After that, the server started experiencing performance drops.

This server has 2 VMs: one with 2 sockets, 24 cores, 440 GB of RAM, and 500 GB of SSD; the other with 1 socket, 14 cores, 48 GB of RAM, and 60 GB of SSD.

The first VM is randomly crashing, doesn't display the summary, and sometimes I can't access it through the console, getting stuck in an infinite connection loop.

NOTE: The server has 2 E5-2680v4 2.4 GHz processors (28 cores/56 threads) and 16 32 GB modules (512 GB of RAM). 2 x 1TB SSDs - RAID 1+0, average usage is shown in the attached image. The other servers are functioning normally, with higher workloads.
