Hi all,
I have no idea if it is ovirt related, nevertheless I give it a try.
Playing around with Red Hat Clustering I created a 3 node cluster.
It seems to works fine, but after changing a couple of things
/var/log/messages is flooding with warnings like:
Mar 13 18:13:58 node3 corosync[1560]: [TOTEM ] Retransmit List: 9b 9c
88 8a 8b 8e 8f 90 91 92 93 94 95 96 97 98 99 9a
Mar 13 18:13:58 node3 corosync[1560]: [TOTEM ] Retransmit List: 9b 9c
88 8a 8b 8e 8f 90 91 92 93 94 95 96 97 98 99 9a
Mar 13 18:13:58 node3 corosync[1560]: [TOTEM ] Retransmit List: 9b 9c
88 8a 8b 8e 8f 90 91 92 93 94 95 96 97 98 99 9a
It seems multicast related, which all seems fine:
[root at node1 ~]# netstat -g
IPv6/IPv4 Group Memberships
Interface RefCnt Group
--------------- ------ ---------------------
lo 1 all-systems.mcast.net
eth0 1 239.192.7.246
eth0 1 all-systems.mcast.net
eth1 1 all-systems.mcast.net
Testing with omping works well.
OK, I'm using home hardware, but the 3 nodes are doing virtually
nothing. It's on one local network, using local storage etc.
Anyone familiar with this problem? That is: after some "heavy"
multicasting packages seem not to arrive.
It might be an virtio network thing, ovirt...?
