Hello everyone.
We are using LVS in quite a large way (volume, distribution and
importance) in solutions that we have implemented for our business. The
way we are using LVS seems to work very nicely but I would appreciate it
if anyone could look at our set up and see if they can see any potenti
This doesn't seem to be in ldirectord, and it would seem to be a nice
addition.
Has anyone looked at implementing this?
Many thanks

I'm using ldirectord to load LVS modules rather than the ipvsadm init script.
Man ipvsadm says you need to start the ipvsadm sync daemon using --start-daemon
state and --stop-daemon. As ldirectord is doing the loading / unloading of
ipvsadm rules then I think the ldirectord script itself needs t
Exactly what I thought. Off to learn Perl ;) Thanks.

Thanks for the response and sorry for messing up the thread formatting
;)
Now I've started to look more into it, it shouldn't be too difficult.
The ldirectord resource agent in Pacemaker needs changing to a
multi-state RA so it can run in slave mode, then ldirectord itself needs
to take another ar

Hello everyone.
We have a 2 node load-balanced MySQL cluster running in active-active
mode. Linux-HA is running on each with LVS balancing connections on the
nodes themselves.
This works great for other production clusters but the MySQL nodes
require connection jailing, i.e. a single client

Hello.
We have around 20 nodes of SLES 11 HAE servers running in 2 or 3 node clusters.
All of them are configured with local resources and ldirectord to load-balance
to the local nodes with a highly available ldirectord resource being able to
move on failover.
I can give more info if required.
1. Yes, ldirectord, cluster, real server, resources all on the same machine.
2. /etc/sysctl.conf is (appended to existing default) :
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.eth0.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.eth0.arp_announce = 2

Check the /var/log/ldirectord.log file for errors and check you can manually
start it yourself:

Hello Andreas.
I don't do session replication with Tomcat, I found it not to work very
well. Instead I just set anything you need sessions on to be source hash

During failover, you will lose sessions from the node that has gone
away. New connections will be sent to the remaining real server(s).
I asked the same thing 3 months ago ;)

That looks fine. This is mine from a production cluster:

I get that when the DB server is overloaded. It's just that the query
times out. Looking at the script to check MySQL in ldirectord, it's very
simple and doesn't specify any timeouts etc so I assume will be using
Perl DBI defaults. Thing is, if the server is heavily loaded and
ldirectord is moving
