Hi Bruce,
Ok I have root-fail over with drbd and it works fine, also my
nfs-failover works great as well. Since the udp port is not supported
yet their goes the display for LTSP. As of right now when the terminal
cluster node goes down the display dies and you press ctrl-alt-del and
it reconnects itsled to the the new init node. This works fine.
The only thing not working at all is the lvs. I tried a ssh test. I ssh
to the clustername and got in. When I shutdow the CVIP current node the
ssh connection dies. The /proc/cluster/lvs file changed nodenumbers fine
though. At no time do I see any output of ipvsadm. I also did downgrade
to the version previously discusses. So I just need to know how to get
this lvs working on TCP ports. I don't even know what commands will help
you troubleshoot this so I just copied a bunch of commands that I think
might help you.
Also anyone needing help with NFS failover or drbd in debian sarge with
openssi 1.2.0 you can contacet me at sm...@au.... I have set
these services up quite a few times now.
