Before adding the drbd pacemaker resource crm status looked fine. After
configuring the resource I get the following error from crm_mon:-
WebData_monitor_0 (node=squeeze, call=11, rc=6, status=complete): not
configured
Here is the crm configuration, and monitor:-

Hi,
Found out how to debug failing resources:-
http://www.clusterlabs.org/wiki/Debugging_Resource_Failures
I managed to clear 1 problem, fuser was not installed; that means psmisc
for Debian users.

Here are a couple of bad looking lines from the debug output:-
/usr/lib/ocf/resource.d/linbit/drbd: 1: [[: not found
/usr/lib/ocf/resource.d/linbit/drbd: 1: 0x080307: not found
/usr/lib/ocf/resource.d/linbit/drbd: 1: Bad substitution
n.b. See full debug report at http://pastebin.com/pjKxBu8K
OCF Return Code: 2
OCF Alias: OCF_ERR_ARGS
Description: "The resource's configuration is not valid on this machine.
Eg. Refers to a location/tool not found on the node."
Recovery Type: hard
Let me know if there's anything else I need to post.
Kind regards,

Hi,
This appeared to be a problem running 3 nodes. Stopping corosync on
one of the nodes levitated the problem.
Is it possible to have a 3 node cluster, 3 running apache, 2 running
DRBD? If so, can someone point me in the direction of how to.
Kind regards,
Jon
