[Gluster-users] How to enable shared_storage?

Mon Nov 21 05:43:53 UTC 2016

Version of glusterfs is 3.8.5

Here what I have installed:
rpm  -ivh
http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm
yum install centos-release-gluster
yum install glusterfs-server
yum install glusterfs-geo-replication

Unfortunately it doesn't work if I just add the script
"/var/lib/glusterd/hooks/1/set/post/S32gluster_enable_shared_storage.sh"
and restart "glusterd".

It seems that I have to install something else..

Sincerely,
Alexandr
