Hello everybody,

for production usage i'm testing  ovirt with gluster.
All components seems to be running fine but whenever I'm testing huge
workload, then node freez. Not the main OS, but VDSM mgmt and attached
services, VMs eg.

What do you mean by freez?

mgmt
oVirt - 4.1.0.4
centos 7.3-1611

nodes ( installed from ovirt image
"ovirt-node-ng-installer-ovirt-4.1-2017030804.iso"  )

OS Version: == RHEL - 7 - 3.1611.el7.centos
OS Description:== oVirt Node 4.1.0
Kernel Version:== 3.10.0 - 514.10.2.el7.x86_64
KVM Version:== 2.6.0 - 28.el7_3.3.1
LIBVIRT Version:== libvirt-2.0.0-10.el7_3.5
VDSM Version:== vdsm-4.19.4-1.el7.centos
SPICE Version:== 0.12.4 - 20.el7_3
GlusterFS Version:== glusterfs-3.8.9-1.el7  ( LVM thinprovisioning in
replica 2 - created from ovirt GUI )

concurently running
- huge import from export domain    ( net workload )
- sequential write to VMs local disk ( gluster replica sequential workload )
- VMs database huge select  (  random IOps )
- huge old snapshot delete  ( random IOps )

In this configuration / workload  is  runnig one hour eg, with no exceptions
, with 70-80% disk load, but in some point VDSM freez  all jobs for a
timeout and VM's are in "uknown" status .
The whole system revitalize then automaticaly in cca 20min time frame (
except the import and snapshot deleting(rollback) )

can anybody help me with this ??
I've got a small tip about swap problem ( in messages), but not shure .....
The similar problem occured in older versions in gluster/ovirt testing ( in
huge workload freeez - but not fatal overload )

You have a storage issue, you should understand why
your storage is failing.

There is also kernel failure to allocated page, maybe this is
related to the storage failure?
