Comment 11 for bug 876648

Another workaround, systemd-based, because yes it still happens on Xenial :

$ systemctl edit my-mount-point.mount
[Unit]
After=glusterfs-server.service
Wants=glusterfs-server.service

$ systemctl cat my-mount-point.mount
# /run/systemd/generator/my-mount-point.mount
# Automatically generated by systemd-fstab-generator

[Unit]
SourcePath=/etc/fstab
Documentation=man:fstab(5) man:systemd-fstab-generator(8)
Before=remote-fs.target

[Mount]
What=localhost:/my-mount-point
Where=/my/mount/point
Type=glusterfs
Options=defaults,_netdev

# /etc/systemd/system/my-mount-point.mount.d/override.conf
[Unit]
After=glusterfs-server.service
Wants=glusterfs-server.service
