About the gluster not starting - use systemd.mount unit files.

here is my setup and for now works:

[root@ovirt2 yum.repos.d]# systemctl cat gluster_bricks-engine.mount
# /etc/systemd/system/gluster_bricks-engine.mount
[Unit]
Description=Mount glusterfs brick - ENGINE
Requires = vdo.service
After = vdo.service
Before = glusterd.service
Conflicts = umount.target

[Mount]
What=/dev/mapper/gluster_vg_md0-gluster_lv_engine
Where=/gluster_bricks/engine
Type=xfs
