io_uring on kernel 7.0.6-2-pve (PVE 9.2.3): guest disk I/O errors (EIO) + filesystem XFS shutdown

[fabian]

could be an issue on either end, or in the combination of both. please keep us posted if any new information comes up!

By the way, I also reproduced the issue on AlmaLinux 10.1 (kernel 6.12.0-124.52.1.el10_1.x86_64) with this command :

fio --name=stress-hdd --ioengine=libaio --iodepth=8 --rw=randwrite \
    --bs=4k --direct=1 --fdatasync=8 --size=20G --numjobs=4 \
    --runtime=1800 --time_based --ramp_time=30 --group_reporting \
    --filename=/tmp/fio-test --output-format=normal,json \
    --output=fio-result.json

However, it seems to last longer / be more complicated to reproduce on this kernel version.

Is anyone on the Proxmox team able to reproduce the problem with a configuration similar to mine?

EDIT

I would like to add that impacted VMs have one less tag on their disk than unaffected VMs :


Healthy VMs (until now) :


The format=raw may impact something ? I don't know what is the difference.
