Hey everyone,
I've got a technical question. In short is it possible to colocate a
group to two master slave resources. I know it's an awkward question.
But in my case I have two drbd resource to two different masterslave
resources (because I use two different hard drives for the two drbd
resources), so what I want is that both filesystems, the virtual ip and
the samba resource are always started and only started when both master
slave resources are master on the same node. (weird right)
Maybe someone has an idea to solves this otherwise, and I am maybe not
thinking right. Here's my crm for the moment (would be nice to have
color coding in the mails somehow :) )
node $id="73288296-569b-41f5-8b14-cf2f0fac8cf7" db01

whole crm configure thingie)
