errors in virtual disc


From: Lentes, Bernd
Subject: errors in virtual disc
Date: Mon, 22 Feb 2021 16:54:15 +0100 (CET)

Hi,

i have a VirtualDomain which often does not boot completely, but stucks in 
emergency mode or while starting D-Bus.
Host and guest are SLES 12 SP5. qemu on the host is qemu-3.1.1.1-45.1.x86_64.
The virtual disc is a raw file which resides on a SAN on an OCFS2 Volume.

In the log i found, beneath other irregular stuff, the following:

I checked the virtual disc with badblocks - no error.
I checked the discs of the SAN via the web-interface from the controller (HP 
MSA G3000 FC) - no error.

Any idea ?
