Linux HA: Resource Stickiness

Hi All,

I have configured the resource stickiness attribute for a simgle resource
which has not been added to a group and this works 100%. I then recreated
the resource under a group, applied the stickiness to the group but when a
node boots up and joins the cluster it shuts down the resource and starts up
the resource again ..

Any ideas as to why this is happening to the group or am I mis-configuring
somewhere ?

Thanks

on the same node or does it move the group to the new node?

Can you _attach_ the logs from that node?
What version is this?

Re: Linux HA: Resource Stickiness [In reply to]

I've managed to resolve the issue with the resource stickiness problem.

What was happening was that the linux systems was not deactivating the LV's
when booting up. I disabled boot.lvm from the /etc/init.d scripts on both
hosts and got linux HA to do the activation via its OCF resource agents.

This not clears the " multi-running error " which i was getting and the
resource now sticks to the failover host

Thats usually the problem. I need to think of a way to make it more
obvious to users that this is the case.
