Hi Alexei,
In order to debug it check the following:
1. Check gluster:1.1 All bricks up ?1.2 All bricks healed (gluster volume heal data info
summary) and no split-brain
2. Go to the problematic host and check the mount point is there2.1. Check permissions
(should be vdsm:kvm) and fix with chown -R if needed2.2. Check the OVF_STORE from the logs
that it exists2.3. Check that vdsm can extract the file:sudo -u vdsm tar -tvf
/rhev/data-center/mnt/glusterSD/msk-gluster-facility.xxxx:_data/DOMAIN-UUID/Volume-UUID/Image-ID
3 Configure virsh alias, as it's quite helpful:alias virsh='virsh -c
qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf'
4. If VM is running - go to the host and get the xml:virsh dumpxml HostedEngine >
/root/HostedEngine.xml4.1. Get the Network:virsh net-dumpxml vdsm-ovirtmgmt >
/root/vdsm-ovirtmgmt.xml4.2 If not , Here is mine:[root@ovirt1 ~]# virsh net-dumpxml
vdsm-ovirtmgmt
<network>
<name>vdsm-ovirtmgmt</name>
<uuid>7ae538ce-d419-4dae-93b8-3a4d27700227</uuid>
<forward mode='bridge'/>
<bridge name='ovirtmgmt'/>
</network>
UUID is not important, as my first recovery was with different one.
5. If you Hosted Engine is down:5.1 Remove the VM (if exists anywhere)on all nodes:virsh
undefine HostedEngine5.2 Verify that the nodes are in global maintenance:hosted-engine
--vm-status5.3 Define the Engine on only 1 machinevirsh define HostedEngine.xmlvirsh
net-define vdsm-ovirtmgmt.xml
virsh start HostedEngine
Note: if it complains about the storage - there is no link in
/var/run/vdsm/storage/DOMAIN-UUID/Volume-UUID to your Volume-UUIDHere is how it looks
mine:[root@ovirt1 808423f9-8a5c-40cd-bc9f-2568c85b8c74]# ll

Once you create your link , start it again.
6. Wait till OVF is fixed (takes more than the settings in the engine :) )
Good Luck!

Ok, I have managed to recover again and no issues are detected this time.I guess this case
is quite rare and nobody has experienced that.
>Hi,>can you please explain how you fixed it? I have set again to global
maintenance, defined the HostedEngine from the old xml (taken from old vdsm log) , defined
the network and powered it off.Set the OVF update period to 5 min , but it took several
hours until the OVF_STORE were updated. Once this happened I restarted the ovirt-ha-agent
ovirt-ha-broker on both nodes.Then I powered off the HostedEngine and undefined it from
ovirt1. then I set the maintenance to 'none' and the VM powered on ovirt1.In order
to test a failure, I removed the global maintenance and powered off the HostedEngine from
itself (via ssh). It was brought back to the other node. In order to test failure of
ovirt2, I set ovirt1 in local maintenance and removed it (mode 'none') and again
shutdown the VM via ssh and it started again to ovirt1. It seems to be working, as I have
later shut down the Engine several times and it managed to start without issues. I'm
not sure this is related, but I had detected that ovirt2 was out-of-sync of the
vdsm-ovirtmgmt network , but it got fixed easily via the UI. Best Regards,Strahil
