[Pacemaker] How to properly define DRBD resources

[Michał Margula]

Hello,

I have another question in the same topic. What if some resource 
(Virtual Machine) requires two DRBDs?

I tried with group and it caused UNCLEAN of a node and it was killed.

So what is proper way to do that? By grouping (if yes grouping what - 
primitives or master-slave?) Or maybe just by proper order?

Unfortunately doing this caused trouble:

primitive primitive-DRBD-saruman-root ocf:linbit:drbd \
         params drbd_resource="drbd21-saruman-root" \
         op monitor interval="29s" role="Master" \
         op monitor interval="31s" role="Slave" \
         op start interval="0" timeout="240" \
         op stop interval="0" timeout="120"
primitive primitive-DRBD-saruman-home ocf:linbit:drbd \
         params drbd_resource="drbd22-saruman-home" \
         op monitor interval="29s" role="Master" \
         op monitor interval="31s" role="Slave" \
         op start interval="0" timeout="240" \
         op stop interval="0" timeout="120"

ms ms-DRBD-saruman-root primitive-saruman-root \
         meta master-max="2" master-node-max="1" clone-max="2" 
clone-node-max="1" notify="true" target-role="Started" is-managed="true"
ms ms-DRBD-saruman-home primitive-saruman-home \
         meta master-max="2" master-node-max="1" clone-max="2" 
clone-node-max="1" notify="true" target-role="Started" is-managed="true"

group ms-DRBD-saruman ms-DRBD-saruman-root ms-DRBD-saruman-home

order DRBD-saruman-after-LVM inf: clone-LVM:start ms-DRBD-saruman:promote
order XEN-saruman-after-DRBD inf: ms-DRBD-saruman:promote XEN-saruman:start



Thanks!
