[Debian-ha-maintainers] LVS problems with 3.2 kernel.

[Brent Clark]

Hi Guys

A while ago, I reported that I was having a problem, whereby ksoftirqd was using 100% of the CPU ( http://lists.graemef.net/pipermail/lvs-users/2012-May/024583.html ).

Given that someone reported that a later kernel, fixed their issue. I proceeded to use Debians backport kernel (i.e. 3.2.0-0.bpo.2-686-pae) on just one of the nodes.

But now there is a new problem. If I restart heartbeat and try to failover to the node running the backport kernel. Heartbeat wont start the virtual ip, and going through the logs, I see the following message.

ResourceManager[14721]:	2012/06/20_10:51:04 info: Retrying failed stop operation [LVSSyncDaemonSwap::master]
ResourceManager[14721]:	2012/06/20_10:51:04 info: Running /etc/ha.d/resource.d/LVSSyncDaemonSwap master stop

ResourceManager[14721]:	2012/06/20_10:51:05 WARN: Machine reboot narrowly avoided!

I am running Debian Squeeze therefore the ipvsadm version is:
ipvsadm  1:1.25.clean-1

I went to http://www.linuxvirtualserver.org/software/ipvs.html, and it says:
ipvsadm-1.25.tar.gz (for kernel 2.6.28-rc3 or later) - November 5, 2008

I see there is a ipvsadm-1.26-1, but I cant see anything in the changelog, for the last entry appears to be
2004-12-08 22:55:27-08:00

Would anyone be able to help.

Kind Regards
