[ovirt-users] non-operational host issues following 4.2 upgrade

Hi all, I upgraded my 4 host converged gluster/ovirt lab setup to 4.2 yesterday, and now 3 of my hosts won't connect to my main data domain, so they're non-operational when I try to activate them. Here's what seems like a relevant passage of vdsm.log: https://paste.fedoraproject.org/paste/JZuxul6-HZjjl8uHzgqL-w The hosts can mount the gluster storage just fine, I can mount to a test location on the hosts, and I can see that the hosts are mounting the storage in the usual place when they attempt to activate. Permissions look normal, too. I undeployed the hosted engine from the three problem machines, in case that was causing an issue. The hosts are running centos 7. Does any of this ring a bell for anyone? Thanks, Jason
