If you had a replicated or distributed volume consisting of master:/brick and slave:/brick, then the client needs to be able to resolve both master and slave. Otherwise, something odd is happening. I would first do grep -i master /etc/hosts and look for anything obvious (repeat for any other brick hostnames in the volume). Next I would run a DNS tcpdump on the client: sudo tcpdump -i eth0 -nn -s0 udp port 53 and do the mount again in a different window, and go back to the DNS tcpdump to see what's seen. If neither of those turn up anything, I would strace the whole mount process: sudo strace -f mount -t glusterfs master:/vol1 /soft 2strace.log and then look at the tail end of this log, and see what it was doing just before it wrote the error to the screen.

[Gluster-users] Problem mounting Gluster volume [3.3]
Dear all, I'm struggling mounting a Gluster shared volume. I was able to create a simple volume with just one brick local to the server node and mount it. But on the client node the mount if failing. The log reports the error (I've attached below the reported log file) : connection to failed (No route to host) But I'm able to ping the server node, so this is confusing me. Any idea what is causing this error ?

Hi, I'm mounting using the following sudo mount -t glusterfs master:/vol1 /soft The command should be right since, it works in on the server node (master) but it is failing on a client.

Does ssh work? I believe that a gluster mount has to succeed by both forward and reverse DNS (like ssh.. well to work without spewing warnings). try traceroute to the server and see if its IP # resolves to the same host. Are the rest of the gluster hosts resolvable in the same way? Do you have old /etc/hosts entries that might interfere with the DNS resolution? hjm -- Harry Mangalam - Research Computing, OIT, Rm 225 MSTB, UC Irvine [m/c 2225] / 92697 Google Voice Multiplexer: (949) 478-4487 415 South Circle View Dr, Irvine, CA, 92697 [shipping] MSTB Lat/Long: (33.642025,-117.844414) (paste into Google Maps) ___ Gluster-users mailing list Gluster-users@gluster.org http://gluster.org/cgi-bin/mailman/listinfo/gluster-users
