I have been asked if multipath has been disabled for the cluster's nvme drives. I have not enabled or disabled multipath for the nvme drives. In Gluster deploy Step 4 - Bricks I have checked "Multipath Configuration: Blacklist Gluster Devices." I have not performed any custom setup of nvme drives other than wiping them in between deployment attempts. Below is the output of lsscsi and multipath -ll on the first host after failed Gluster deployment and before cleanup. Thanks! Should I set up multipath? If so, if you could point me to documentation re setup for oVirt. I still have a lot to learn and appreciate any direction.
