GlusterFS - 'Host not connected' when creating a volume on VBox VMs

GlusterFS - 'Host not connected' when creating a volume on VBox VMs

I'm trying to deploy a simple GlusterFS cluster on CentOS using
Virtualbox. I only have two nodes (gluster-node1 and gluster-node4) with
two bricks each and I'm creating a volume with replica level 2.
When I issue the volume create command on gluster-node4 I get this error:
'Host gluster-node1.test not connected'. The glustersd daemon is running
on both host and if I check the peer status it returns 'State: Peer in
Cluster (Disconnected)' on both host. I checked the
/var/log/glusterfs/etc-glusterfs-glusterd.vol.log file on gluster-node4
and found this error 'E [socket.c:2157:socket_connect_finish]
0-management: connection to 192.168.1.61:24007 failed (No route to host)',
but if I try to ping or ssh to the gluster-node1 host it works without any
problem.
As far as I can see there is no rule in iptables that would block this
connection and I can see a route in the routing table.
# iptables --list -n

(eth1 is an Host-only interface on the Vbox VMs)
Am I missing something? Any suggestions?
