Thanks, Brian, for the hint. I've changed /etc/hosts with respect to your comment, but it didn't help either. The problem (from my perspective) in smth else, e.g. why, when I try to do the following, I see the blank response in tcpdump: [root at host1 ~]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000 link/ether 00:25:90:30:34:42 brd ff:ff:ff:ff:ff:ff inet 46.../27 brd 46.182.25.159 scope global eth0 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:25:90:30:34:43 brd ff:ff:ff:ff:ff:ff inet 192.168.1.192/24 brd 192.168.1.255 scope global eth1 [root at host1 ~]# tcpdump -i eth1 'port 27004' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes ^Z [2]+ Stopped tcpdump -i eth1 'port 27004' [root at host1 ~]# bg [2]+ tcpdump -i eth1 'port 27004' & [root at host1 ~]# gluster peer probe host2 Probe on localhost not needed [root at host1 ~]# fg tcpdump -i eth1 'port 27004' ^C 0 packets captured 117 packets received by filter 52 packets dropped by kernel So (by whatever reason) Gluster doesn't send a packet to anywhere through ethernet. Guys, any ideas?
