Hi We have used corosync (and pacemaker) successfully some years in an IPV4 environment. Now we should be using IPV6 for the next project but this is proving difficult. I presume I have not understood the configuration but I have searched high and low to find examples. Results with Debian Wheezy version 1.4.2 and self compiled 1.4.6 versions are identical: 2013-06-25_14:23:34.87618 Jun 25 14:23:34 corosync [MAIN ] Successfully read main configuration file '/etc/corosync/corosync.conf'. 2013-06-25_14:23:34.87706 Jun 25 14:23:34 corosync [TOTEM ] Initializing transport (UDP/IP Unicast). 2013-06-25_14:23:34.87707 Jun 25 14:23:34 corosync [TOTEM ] Initializing transmit/receive security: libtomcrypt SOBER128/SHA1HMAC (mode 0). 2013-06-25_14:23:34.98701 corosync: totemip.c:104: totemip_equal: Assertion `addrlen' failed. Here is the config file (IP addresses partly hidden): Of course I have also tried with abbreviated ip6 addresses (no leading 0 and :: for consecutive :0:0: groups) I even tried without any : at all. Same result every time. totem { version: 2 nodeid: 1 # A secauth: on vsftype: none token: 4000 consensus: 7000 token_retransmits_before_loss_const: 20 window_size: 20 max_messages: 20 transport: udpu interface { member { memberaddr: 2aff:ffff:0131:0203:0000:0000:0001:0002 # A } member { memberaddr: 2aff:ffff:0100:40eb:0000:0000:0001:0002 # B } member { memberaddr: 2aff:ffff:0d16:2d90:0000:0000:0000:0002 # C } ringnumber: 0 bindnetaddr: 2aff:ffff:0131:0203:0000:0000:0001:0002 # A mcastport: 694 } } amf { mode: disabled } service { # Load the Pacemaker Cluster Resource Manager ver: 0 name: pacemaker } aisexec { user: root group: root } logging { fileline: off to_syserr: yes debug: off timestamp: on logger_subsys { subsys: AMF debug: off } } If anyone can tell me where I'm going wrong I'd be very thankful.
