The vdsm log from the non-operational host should have some information 
regarding this.

Can you also check if there are errors in the gluster mount logs - at 
/var/log/glusterfs/rhev-data-center-mnt-glusterSD*

Also, worth checking that glusterd ports are open on the gluster hosts 
(we had an issue where HE install overrides glusterd ports and gluster 
volume was inaccessible)
