I think I found the answer to glusterd not starting. https://bugzilla.redhat.com/show_bug.cgi?id=1472267
Apparently the version of gluster (3.12.15) that comes packaged with ovirt-node 4.2.8 has a known issue where gluster tries to come up before networking, fails, and crashes. This was fixed in gluster 3.13.0 (apparently). Do devs paruse this list? Any chance someone who can update the gluster package might read this?
