Hi Strahil,
The majority of the VMs are UEFI. But I do have some Legacy BIOS VMs and they
are corrupting too. I have a mix of RHEL/CentOS 7 and 8.
All of them are corrupting. XFS on everything with default values from
installation.
There’s one VM with Ubuntu 18.04 LTS and ext4 that corruption
Usually distributed volumes are supported on a Single-node setup, but it
shouldn't be the problem.
As you know the affected VMs , you can easily find the disks of a VM.
Then try to read the VM's disk:
sudo -u vdsm dd
if=/rhev/data-center/mnt/glusterSD/gfs1.server.pt:_gfs1data//images//
of=/d
Damn...
You are using EFI boot. Does this happen only to EFI machines ?
Did you notice if only EL 8 is affected ?
Best Regards,

As you use proto=TCP it should not cause the behaviour you are observing.
I was wondering if the VM is rebooted for some reason (maybe HA) during
intensive I/O.

Hi Strah
Are you sure you don't have any heals pending ?
I should admit I have never seen this type of error.
Is it happening for all VMs or only specific ones ?

Hi Stefan,
you can control the VM's cache (if Linux) via:
- vm.vfs_cache_pressure
- vm.dirty_background_ratio/vm.dirty_background_bytes
- vm.dirty_ratio/vm.dirty_bytes
- vm.dirty_writeback_centisecs
- vm.dirty_expire_centisecs
I would just increase the vfs_cache_pressure to 120 and check if it f
Hi Strahil.
I’m not using barrier options on mount. It’s the default settings from CentOS
install.
I have some additional findings, there’s a big number of discarded packages on
the switch on the hypervisor interfaces.
Discards are OK as far as I know, I hope TCP handles this and do the proper
Hi Stefan,
Please check out https://bugzilla.redhat.com/1884050 if it fits your
problem.
The resolution was having the right guest-agent installed in the
guest(qemu-guest-agent or ovirt-guest-agent).

I'm quite new to oVirt, so my apologizies if I'm asking something dead obvious:
