OLVM: KVM host in "Non Operational" state after a reboot. (Doc ID 2699923.1)

Last updated on JANUARY 03, 2021

Applies to:

Linux OS - Version Oracle Linux 7.8 with Unbreakable Enterprise Kernel [4.14.35] and later
Linux x86-64


After an unexpected reboot of KVM host, it is marked as Non-Operational from the OLVM GUI.

Switching the host to Maintenance mode and activating it would still leave the host at the Non-operational state.

The following errors are seen in /var/log/vdsm/vdsm.log of the KVM host:
