GlusterFS Quick Setup on Fedora 26

1. Prepare atleast 2 nodes

2. Create bricks

mkfs.xfs -i size=512 /dev/sdb1
mkdir -p /data/brick1
echo '/dev/sdb1 /data/brick1 xfs defaults 1 2' >> /etc/fstab
mount -a && mount

3. Install package (both nodes)

yum install glusterfs-server

4. Allow communication (both nodes)

iptables -I INPUT -p all -s -j ACCEPT

5. Configure trusted pool

gluster peer probe server2 # from server1
gluster peer probe server1 # from server2
gluster peer status # both servers

6. Create bricks to export (both nodes)

mkdir -p /data/brick1/gv0

7. Create gluster volume (from any single node)

gluster volume create vg0 transport tcp replica 2 server1:/data/brick/gv0 server2:/data/brick/gv0
gluster volume start gv0

8. Mount the volume inside the servers (both nodes)

mount -t glusterfs $(hostname):/gv0 /mnt
