systemctl enable glusterd
systemctl start glusterd

gluster peer probe node1

Create Volume

gluster volume create docker-config replica 2 vm-docker0:/mnt/gluster_docker-config vm-docker1:/mnt/gluster_docker-config force
gluster volume create docker-data replica 2 vm-docker0:/mnt/gluster_docker-data vm-docker1:/mnt/gluster_docker-data force


gluster volume start docker-config
gluster volume start docker-data


gluster volume status

Connect client to volume

mount -t glusterfs vm-docker0:/docker-config /srv/docker-config
mount -t glusterfs vm-docker0:/docker-data /srv/docker-data

• fstab

vm-docker0:/docker-config /srv/docker-config glusterfs defaults,_netdev 0 0
vm-docker0:/docker-data /srv/docker-data glusterfs defaults,_netdev 0 0

• systemd (often fstab is loaded before gluster, therefore not mounting gluster shares)
• /etc/systemd/system/gluster-mounts.service

cd /etc/systemd/system
touch gluster-mounts.service
