I have a few servers with Proxmox and a couple of VMs and LXCs on each of it. When I did apt update && apt dist-upgrade, sometimes all my VMs and LXCs were automaticaly rebooted during an update process, perhaps due to update qemu or kvm or something like that. I guessed it is normal behaviour...

I am trying to find the best config for my Proxmox on ZFS rpool. I know that ZFS eats so many RAM for caching. When I am not limiting amount of arc in /sys/module/zfs/parameters/zfs_arc_max, sooner or later I have more than 90% of RAM used. I have for example 64GB physical RAM, my one only VM...

Hello, I have one PBS in one location and second PBS in second location. I want to make a backup sync from time to time (let say every weekend). I want to sync all my backups from one locations to the second, but I choose to sync last only. I noticed a weird behaviour. I thought only last...

Hello, I am aware of informations provided by many people here in forum about buying enterprise grade SSD for Proxmox VE. But many people runs Proxmox in own homelab with low budget HW. I have for example this MB from Supermicro , now I have one M2 SSD Patriot M.2 P300 256GB (in MB) with 4x...

Hi all, I was wonder what exactly would happen when I make a snapshot of live linux VM and then after a couple of hours I will click on rollback ? I supposed that VM will be at the same state when I did a snapshot. I am pretty sure of that. But I was wonder what will happen after that. My...
