Hi guys once again :-)
my resource Hosting on top of ms_drbd_r0 keeps restarting even if the
changes aren't local to the node.
By that, i mean Hosting get's restarted on node1 even if i restart or
outdate and demote node 2.
My constrains:
colocation Hosting_on_ms_drbd_r0 inf: Hosting ms_drbd_r0:Master
order ms_drbd_r0_b4_Hosting inf: ms_drbd_r0:promote Hosting:start
My resources:
primitive Hosting ocf:heartbeat:Xen \
params xmfile="/etc/xen/Hosting.cfg" \
meta target-role="Started" allow-migrate="true" is-managed="true" \
op monitor interval="120s" timeout="300s"
primitive drbd_r0 ocf:linbit:drbd \
params drbd_resource="r0" \
op monitor interval="15s" role="Master" timeout="30s" \
op monitor interval="30s" role="Slave" timeout="30"
ms ms_drbd_r0 drbd_r0 \
meta notify="true" master-max="2" inteleave="true"
I use location to:
location cli-prefer-Hosting Hosting \
rule $id="cli-prefer-rule-Hosting" inf: #uname eq ibm1
Example:
Shuting down heartbeat on node2/ibm2, while resource is running
perfectly fine on node1, makes resource Hosting restart on node1.

.
Please advise me on how to configure ordering and collocation
constrains, to not get Hosting resource restarted each time when
something happens to backup drbd resource on the second node.
Thank you.
