Re: [ovirt-users] VDSM hang

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.

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 .
