Host Non-operational issue - Storage domain monitoring thread slows down

Implemented following change to resolve/avoid this issue:

1)      Check the current configuration on RHEV Manager using after switching to root:

engine-config -g MaxStorageVdsTimeoutCheckSec

2)      Change the current configuration (change value to 75):

rhevm-config -s MaxStorageVdsTimeoutCheckSec=75

Now 2^nd parameter  “vdsHeartbeatInSeconds”

3)      Check the current configuration:

engine-config -g vdsHeartbeatInSeconds

4)      Change the current configuration (change value to 20) if it’s not set to 20 already:

rhevm-config -s vdsHeartbeatInSeconds=20

5)      Restart the ovirt-engine service after this.

               /etc/init.d/ovirt-engine restart

Check the changed configurations:

engine-config -g MaxStorageVdsTimeoutCheckSec

engine-config -g vdsHeartbeatInSeconds
