Atin, In debug, the glusterd log file is pretty sizeable. I do see regular: [2015-12-01 20:29:14.407105] E [MSGID: 106167] [glusterd-handshake.c:2073:__glusterd_peer_dump_version_cbk] 0-management: Error through RPC layer, retry again later And ones like: [2015-12-01 20:29:45.057998] C [rpc-clnt-ping.c:165:rpc_clnt_ping_timer_expired] 0-management: server 172.18.56.55:24007 has not responded in the last 30 seconds, disconnecting. Hopefully there is something in there that can give a clue as to what is going on. Incidentally, to enable debug using the RPMs, the code in /etc/sysconfig/glusterd is inaccurate. The init file looks for LOG_FILE and LOG_LEVEL rather than the GLUSTERD_LOGLEVEL and GLUSTERD_LOGFILE that are in there as examples.

That's interesting, 'gluster peer status' or 'pool list' is a local node operation and doesn't incur RPC calls. Until and unless it takes time to communicate back to CLI because of a poor N/W, I don't see any reason why would it take such a long time. Can you run glusterd with debug log enabled and share the *glusterd.log file with us? ~Atin > > > > I have 10 nodes all on the same network and currently ZERO volumes or > bricks configured.
