Hello Markus,
Thanks for your reply. I think this will not work in our case because the libvirtd/vm
process is not crashed and after unpausing the vm runs without problems.
Is it possible to unpause your vm in this situation or is the process really crashed?
Jasper

unknown storage error"
Hi Jasper,
from time to time we see a similar behaviour. All of a sudden a VM pauses due to
some IO error. But it takes 5 months to occur. Our /var/log/libvirt/qemu/<vm>.log
gives
qemu-system-x86_64: block.c:2806: bdrv_error_action: Assertion `error >= 0'
failed.
Currently we are waiting to capture the next crash. I do not know if your error
allows to enforce cores for in depth analysis. If yes you should activate
1) /usr/lib/systemd/system/libvirtd.service
LimitCORE=infinity
2) /etc/security/limits.conf
* soft core unlimited
Markus

Betreff: [ovirt-users] Vm suddenly paused with error "vm has paused due to unknown
storage error"
Hi all,
Since we upgraded our Ovirt nodes to CentOS 7 a vm (not a specific one but never more then
one) will sometimes pause suddenly with the error "VM ... has paused due to unknown
storage error". It happens now two times in a month.
The Ovirt node uses san storage for the vm's running on it. When a specific vm is
pausing with an error the other vm's keeps running without problems.
The vm runs without problems after unpausing it.
Versions:
CentOS Linux release 7.1.1503
vdsm-4.14.17-0
libvirt-daemon-1.2.8-16

Has anyone experienced the same problem or knows a way to solve this?
