Hello All,
I am trying to setup a three way replicated Gluster Storage which is
exported by NFS Ganesha.
This 3 node Ganesha cluster is managed by pacemaker and corosync. I want
to use this cluster as a backend for several different web-based
applications as well as storage for mailboxes.
The cluster is working well but after triggering the failover by
stopping the ganesha service on one node, the ganesha services on the
other two nodes are also stopping after a couple of minutes, bringing
down the whole cluster.
Setup:
3 CentOS Gluster Servers with Ganesha
2 CentOS Clients
Packages:
glusterfs-libs-3.10.11-1.el7.x86_64
glusterfs-3.10.11-1.el7.x86_64
glusterfs-fuse-3.10.11-1.el7.x86_64
