question mark in oVirt - "cannot acquire state change lock"
This is a multi-part message in MIME format. --------------000004040200040204070407 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello all, how can I eliminate question mark from "hanged" VM? ( it happened in shutdown process via oVirt env. ) Best solution without hypervizor reboot, meaning "power off" , "kill" or another workaround for that VM . Will help removing task DB record from oVirt mgmt server - if exists , ofcourse ?? Running gluster 3.7.5 / oVirt 3.5.2 / libvirt-daemon-kvm-1.2.8-16.el7_1.5.x86_64 on centos 7.1.1503 . thx a lot. Pa.

This is very interesting, I have seen this error in testing environment on rhel 7.1 or 7.2. Can you provide vdsm logs showing the time of the error? Nir
This is a multi-part message in MIME format. --------------070108050505080207080606 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello, some requested outputs Vdsm generate a huge count of records in time, so I'm not shure if "hang" time is still included . Problems occured 17-feb-2016 17:00-18:00 when VM shutdown was requested. But some performance problems occured a day before ( I'm not shure about application problem = JAVA = running EBS ) In mail before I attached pointers to bugs with any workaround killall -9 libvirtd rm /var/run/libvirtd.pid /etc/init.d/libvirt-bin restart which would solve current situation. Is this workaround safe enought?? Will stay VMs running ??? THX for any help, because I can't reboot hypervizor due huge DB traffic and no VM migration possibility via oVirt engine. ( mem synchro overloaded ?? ) Pa. PS: logs sent directly to RH. On 17.2.2016 08:22, Nir Soffer wrote:
