I am following the guide posted here: http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Clusters_from_Scratch/ I have two servers with dual NICS: Server 1 NIC-A: 10.89.99.31 NIC-B: 192.168.1.5 Server 2 NIC-A: 10.89.99.32 NIC-B: 192.168.1.10 I want to use NIC-B on both machines to carry corosync traffic. I got down to this section: 1. export ais_port=4000 2. export ais_mcast=226.94.1.1 3. export ais_addr=`ip addr | grep “inet” | tail –n 1 | awk ‘{print $4}’ | sed s/255/0/` 4. env | grep ais_ais_mcast=226.94.1.1 The last command did not produce any output, so I edited the corosync.conf file manually. I have attached a copy of the file as it appears on both servers. I am able to start corosync up on Server 1 with no problems. On Server 2, I am getting the errors below: Jun 7 01:06:48 KNTCLFS002 corosync[2452]: [TOTEM ] Initializing transport (UDP/IP Multicast). Jun 7 01:06:48 KNTCLFS002 corosync[2452]: [TOTEM ] Initializing transmit/receive security: libtomcrypt SOBER128/SHA1HMAC (mode 0). Jun 7 01:06:48 KNTCLFS002 corosync[2452]: [TOTEM ] Unable to bind the socket to receive multicast packets: Permission denied (13) Jun 7 01:06:48 KNTCLFS002 corosync[2452]: [TOTEM ] Could not set traffic priority: Socket operation on non-socket (88) Jun 7 01:06:48 KNTCLFS002 corosync[2452]: [TOTEM ] The network interface [192.168.1.10] is now up. Jun 7 01:07:32 KNTCLFS002 corosync[2452]: [TOTEM ] Totem is unable to form a cluster because of an operating system or network fault. The most common cause of this message is that the local firewall is configured improperly. I have made sure that iptables is turned off and selinux is set to permissive. When I run the command ‘corosync-blackbox’ I get this: rec=[1056] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1057] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1058] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1059] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1060] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1061] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1062] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1063] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1064] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1065] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1066] Log Message=The consensus timeout expired. rec=[1067] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88) rec=[1068] Log Message=entering GATHER state from 3. rec=[1069] Log Message=Totem is unable to form a cluster because of an operating system or network fault. The most common cause of this message is that the local firewall is configured improperly. I can ping each machine from the other one. Any help will be greatly appreciated. Thanks, William |
