Hi all, my ovirt cluster has got 3 Hypervisors runnig Centos 7.5.1804 vdsm is 4.20.39.1-1.el7, ovirt engine is 4.2.4.5-1.el7, the storage systems are HP MSA P2000 and 2050 (fibre channel).
I need to stop one of the hypervisors for maintenance but this system is the storage pool manager.
For this reason I decided to manually activate SPM in one of the other nodes but this operation is not successful.
Why would you do that ?Just put the host in maintenance and the system will evacuate all VMs and another host will be promoted as SPM . Once the host is in maintenance - you can proceed with your tasks. P.S: Don't forget to remove the mainteance mode once you are over. Best Regards,Strahil Nikolov
