Hi,
I have a hyperconverged ovirt 4.3.10 installation. One host is unresponsive.
This has happened in the past but most often resolved itself within a few
minutes. This time it is a different beast.
The host does not come back. Putting the host in maintenance is not possible
because "Host is unresponsive but has running virtual machines". Putting the
host into local maintenance on the local CLI does not help. Global maintenance
does not have any effect either. The host has been rebooted several times both
locally and via the web interface on the engine, which worked but did not
resolve the issue.
