I've had a small issue now for about a month with my proxmox node. I have 10 VMs running on my node, all VMs are fine, and backup fine. Just this one VM with a 300GB partition is giving me fits.
It runs fine, as long as I don't try to run backups nightly on it. Every single time I try to run backups, it kills the OS drive and I get IO errors out of it. Nothing wrong with my physical drives, other VMs backup fine, no issues. I've also, to hedge my bets, put two new SSD drives in and moved the VMs disk to that new drive pair (ZFS MIRROR). Same thing happens.
Only happens if I try to backup the VM. The OS will kick IO errors and stop working, I reboot the VMs linux OS and it boots into recovery mode for linux and won't get out of it, says drive is toast. If I restore the last good backup I have, it works fine, until I try to backup again.
I can also make a snapshot just fine, I tested that for a few days. If I manually run a snapshot at anytime, it works fine, no issues.
I'm running PVE 8.0.3. The backup mode is snapshot, ZSTD.
