Hi everyone,
just want to see if someone came across this situation and what should I do?
I have Proxmox VE 8.0 installed on my Intel NUC i3-1220P with 64G RAM with around 4 VMs and 5 CT running.
It is (was?) part of a cluster and everything seemed to be just fine, until...
During the last week it already crashed twice, both it was ZFS component that caused that.
I am not a Linux guru so analysing crash dumps is not something I can do but I copied-pasted dmesg output to Google and it told me
Short version: your kernel crashed inside the ZFS module while a write-back worker was flushing ZFS data. It faulted on an invalid pointer in the ARC eviction path, then the worker thread died noisily. You were also under heavy memory pressure (swap basically exhausted), which likely helped trigger the ARC eviction path that crashed.
I attached relevant piece of dmesg output if someone want to have a look.
It also corrupted replicated image - luckily, I have backups.
I will keep the server like that if you want me to do some debug/troubleshooting steps.
Cheers.
