-------------------

Already tried with the following :-
1. Reboot the glusterd and glusterfsd services..
2. Reboot the storage nodes..
3. Network should not be a problem as it was working before...and stop
working suddenly...anyways i have 10G network with bonding for gluster...
3. Selinux disabled on all the nodes..
4. Iptables allowed the below ports for gluster (Even try with stop the
iptables):-

-----------------
# glusterd
-A INPUT -p tcp -m tcp --dport 24007 -j ACCEPT

# Ports for gluster volume bricks (default 100 ports)
-A INPUT -p tcp -m tcp --dport 24009:24208 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 49152:49351 -j ACCEPT
------------------

Network Topology in My ENV :-

On Each Host i have 6 ethernet cards :-
eth0 :- ovirtmgmt
eth1 :- VM Network (Private)
eth2 & eth3 (Bond1) :- VM Network (Public)
eth4 & eth5 (Bond0) 10G :- Storage Gluster use...

I can ping telnet other servers on this storage network but still in the
brick logs it's disconnecting connection error....please help me to solve
this problem...

Thanks,
Punit
