Hi All,
I've been looking for a while but haven't found any resolution to my issue. I have 3 separate proxmox nodes on 3 machines. I set up a PBS instance on a 4th machine (Synology NAS). Right now 2 of my nodes back up with no issue. The 3rd node does not back up and is giving errors. The only difference with this 3rd instance is that I have Proxmox running on a ZFS pool. I'm running Proxmox 8.4.14 on all nodes and PBS 3.3.3. Here's what I'm getting as an error on the first LXC (I've tried starting from the 2nd but get the same errors).
Any help would be much appreciated!
