Thank you Donald! Your and Strahil's suggested solutions regarding disabling multipath for the nvme drives were correct. The Gluster deployment progressed much further but stalled at TASK [gluster.features/roles/gluster_hci : Set granual-entry-heal on] ********** task path: /etc/ansible/roles/gluster.features/roles/gluster_hci/tasks/hci_volumes.yml:67 with "stdout": "One or more bricks could be down. Please execute the command again after bringing all bricks online and finishing any pending heals\nVolume heal failed."
