[Pacemaker] Problems with colocation/order with drbd tree-node-setup

[Schmidt, Torsten]

i think you're right here; 
i simply sticked to the example on http://www.drbd.org/users-guide/s-pacemaker-stacked-resources.html#s-pacemaker-stacked-dr 

so i've done:
crm configure delete co.ms.drbd.mysqlstack_on_res.ip.mysql

now 'ptest' gives:
WARN: Resource res.drbd.mysqlstack:0 cannot run anywhere
WARN: Resource res.ip.mysql cannot run anywhere

i think, there's no problem with the ordering but still ip (and mysqlstack) cannot be run anywhere !?

Mit freundlichen Grüßen / with kind regards

Torsten Schmidt

I am unsure this is the source of your problems, but I think you have a colocation restraint too much.

> colocation co.ms.drbd.mysqlstack_on_res.ip.mysql inf:
ms.drbd.mysqlstack res.ip.mysql 

Why this?

You already force both ms.drbd.mysqlstack and res.ip.mysql onto ms.drbd.mysqldb:Master, so there is no need to force ms.drbd.mysqlstack onto res.ip.mysql too.
