I was thinking if there was something to do with glusterd daemon,so i tried to stop the daemon just started, bang~~, everything was back to normal As soon as sy-host-2 started the glusterd daemon, sy-host-1 showed up something in the log(/var/log/glusterfs/glusterd.log): [2015-04-28 06:08:35.342054] E [client-handshake.c:1496:client_query_portmap_cbk] 0-img-client-1: failed to get the port number for remote subvolume. Please run 'gluster volume status' on server to see if brick process is running. [2015-04-28 06:08:35.342223] I [client.c:2215:client_rpc_notify] 0-img-client-1: disconnected from img-client-1. Client process will keep trying to connect to glusterd until brick's port is available I ran the command “gluster volume status” on sy-host-2, nothing but normal Any help is great appreciated -- Jay _______________________________________________ Gluster-users mailing list [email protected] http://www.gluster.org/mailman/listinfo/gluster-users
