I have two servers with SLES11 SP1 x86_64 and compiled last version of glusterfs 3.1.1.
firewall is disabled on both nodes and they are on the same network.

I put both hostnames in the hosts file, so that each node can resolv the others hostname correctly
192.168.8.104   virt-zabbix-02
192.168.8.105   virt-zabbix-03

this is my config on both nodes: "/etc/glusterfs/glusterd.vol"
volume management
   type mgmt/glusterd
   option working-directory /etc/glusterd
   option transport-type socket,rdma
   option transport.socket.keepalive-time 10
   option transport.socket.keepalive-interval 2
end-volume

virt-zabbix-02# gluster peer status
No peers present

this is okay, but then, when I want to add the other node to the cluster, the "glusterfsd" dies on "virt-zabbix-02" where I type the command and a core-dump file is generated:
virt-zabbix-02# gluster peer probe virt-zabbix-03

so I start the "gluserfsd" on virt-zabbix-02 again - a few secounds later the glusterfsd dies on the other node virt-zabbix-03 and there also a core-dump file is generated

starting the glusterfsd on virt-zabbix-03 again, let die the glusterfsd on virt-zabbix-02 and so on
so I make sure the daemon is stopped on both hosts.
the peer file generated on the nodes are different one is named with the hostname, the other with the IP:
virt-zabbix-02:#  cat /etc/glusterd/peers/virt-zabbix-03
uuid=
state=0
hostname1=virt-zabbix-03

virt-zabbix-03:# cat /etc/glusterd/peers/192.168.8.104
uuid=
state=0
hostname1=192.168.8.104


so I see the uuid is empty in both files and I fill it with the uuid from each others "/etc/glusterd/glusterd.info" file:
virt-zabbix-02:/ # cat /etc/glusterd/glusterd.info
UUID=a9b660c5-456d-4e96-9bdd-d23c917ae941
virt-zabbix-03:/ # cat etc/glusterd/glusterd.info
UUID=255540da-4b86-46f2-963c-3214e2c5e28a

virt-zabbix-02:/ # cat /etc/glusterd/peers/virt-zabbix-03
uuid=255540da-4b86-46f2-963c-3214e2c5e28a
state=0
hostname1=virt-zabbix-03

virt-zabbix-03:/ # cat /etc/glusterd/peers/192.168.8.104
uuid=a9b660c5-456d-4e96-9bdd-d23c917ae941
state=0
hostname1=192.168.8.104


now I start "glusterfsd" on both nodes again and both daemons keep running and I can type the command:
virt-zabbix-02:/ # gluster peer status
Number of Peers: 1

Hostname: virt-zabbix-03
Uuid: 255540da-4b86-46f2-963c-3214e2c5e28a
State: Establishing Connection (Connected)

I'd like to create my first test volume:
gluster volume create mytest transport tcp virt-zabbix-02:/gfs1 virt-zabbix-03:/gfs1
Creation of volume mytest has been unsuccessful
Host virt-zabbix-03 not connected

so I restart the glusterfsd on virt-zabbix-03 and the daemon on virt-zabbix-02 dies again

has some one any idea whats going wrong?

kind regards
