I am having some problems with a new-to-me used Xeon E3-1225 server I'm trying to turn into home server.
Currently, I have it setup with Proxmox installed, two 1TB hard drives (different makes/models) in a RAID1 ZFS pool for the base operating system and ideally some VMs. I have two 4 TB HDDs that I was going to use for mass storage, in a ZFS RAID1 also, but currently just hold some back up data.
At the moment, I just have Proxmox installed, no VMs or containers running beyond the default setup. I was moving data from the 4 TB HDD to the newly made ZFS pool on the 1TB disks (root home directory), but in doing so Proxmox repeatedly became unresponsive. I've tried 3 times, and each time the system drops the network connection and hangs and I'm not sure what's happening anymore.

More recently, I tried doing the data backup to an external drive using a Linux Mint Live CD, and have not run into system crashing, so I don't believe it to be hardware related, but likely a bad setup/practice on my part.
Below is the kernel log after boot up, where errors started happening that I'm not entirely sure what's going on.
I truncated the kernel log, but the log is filled with the repeated part indefinitely.
