Hi Horms,
I've tried also Debian's linux-image-2.6.12-1-686 and the symptoms are the same:
- Load average fixed at 2.00
- Failover and failback works fine as in 2.6.11
the Sync Daemon get started with this command line:
$IPVSADM --start-daemon master --mcast-interface $IFACE
$IPVSADM --start-daemon backup --mcast-interface $IFACE
where $IFACE is the NIC of the hearbeat LAN on the Bcm5700. I've also
tried to use the Intel NIC but the problem is the same.
debld1:~# ipvsadm -v
ipvsadm v1.24 2003/06/07 (compiled with popt and IPVS v1.2.0)
Horms, I can live with this load average but I suspect that it is not normal.
Another option, just to say to have tried all ;-), is with Debian Kernel 2.4.27.
Really, is there some one on the list which is using this setup who
can report about this?
Regards,
Luca
