Hello all,
I've been researching Linux-HA for a bit now and have been thoroughly
impressed with the project. Thanks so much for contributing all of
this effort.
I have a few questions about a simple setup:
* Node 1 is an active webserver with static content
* Node 2 is a passive failover (s
Hello,
I have a couple XEN resources setup and work fine until a node gets fenced.
The resources fail over to the running node which is good. Then, when the dead
node is rebooted and comes back the XEN resources immediately try to start on
the rebooted node and fail, the node gets fenced again

Hi,
I'm using now the most actual xen0 stonith plugin, that Serge attachted
the 2008-02-28 to this thread.
I thought I configured everything correct but it seems that the stonith
clone cannot be started on my 2nd node.
I must admit I configured the Clone via hb_gui but I still have some issues.

Hi Dominik. Thank you for the fast answer.
Setting crm to "respawn" at least prevent the machines from rebooting,
and gives me a fair chance to run other diagnostics.
I'm sorry, I just realized that

Hi,
I am using HA-V2 and would like to implement a script or program which can
be used for real load balancing. It should run every x seconds and
determine the cpu+IO load of the host and change a regarding node
attribute. Then crm should use this attribute and a threshold in location

I've set up a couple of 2 node cluster with ha 2.1.3 drbd 8.2.4 and

Next will be 2 nodes mysql and jboss clusters.

Hi all,
I am setting up a simple HA cluster for mysql database (active/passive
with DRBD).
My 2 servers will have a direct network link (bonded) for DRBD
replication and heartbeat communication.
For database access, network links will also be redunded, toward 2
different switches.
My question is:
