Hello,
Sorry, this message is quite long.
I have some Heartbeat2 newbie questions about the following setup, i was
unable to find the right solutions for these from the web site.
My current configuration :
- 2 nodes, 'av' and 'sc430', active/active cluster
- 'group_1' resources should run on 'av' as long as possible
- 'group_2' resources should run on 'sc430' as long as possible
- as long as possible means for me that the monitored resources can
start and run on the node and that the node has network connectivity.
- In my configuration below i setup auto_failback to off to have to put
things back in place _manually_ if something bad happens.
There are my questions :
- How to modify my current cib.xml to be able to run resources on a node
as long as the node can ping at least one of the routers ?
- How to avoid pingd to move my resources from one node to the other
while the first node network connectivity is down for less than 30
seconds (i modified the -d parameter, but i'm not sure it's enough)
- How can i avoid stopping resources everywere if there is no network
connectivity at all on any node ? The main background here is to migrate
resources only if the other node has some network connectivity otherwise
do nothing (let the resources run).
- I have exactly the same setup to do with auto_failback on. Is changing
the auto_failback option in ha.cf enough to achieve this ?
Thanks a lot for your attention and help.
