Hello ndevos, Per your suggestion on IRC, i managed to take the tcpdump and run the .pcap file thru the wireshark utility. I posted the wireshark output @ http://fpaste.org/FMMv/ Could you pls provide further suggestion on what could be the issue for my gluster mount failing. For records... dumping some data related to the problem... getting mount error...
