Repos and packages to install.

sudo yum -y --enablerepo=extras install centos-release-gluster ;
sudo yum -y install glusterfs-server

Or just the client packages.

sudo yum -y --enablerepo=extras install centos-release-gluster ;
sudo yum -y install glusterfs-fuse glusterfs

If you encounter this error in the glusterfs log, nominally /var/log/glusterfs/$MNTNAME.log, it means the client version does not match the server version.

To fix, use the same client version.
