Oh no.
Now you have duplicated all nodes, and will always get "unclean" nodes.
Is this some variant of:
http://www.clusterlabs.org/wiki/Initial_Configuration#A_Special_Note_for_People_Switching_Cluster_Stacks
Could that be the root cause of your duplicate node instances with
different ids?
Yes.
Corosync uses uname (output of 'uname -n') as ID of the node, and
Heartbeat uses UUID as ID of the node. Therefore, on Heartbeat stack,
unclean node is added when I loaded the following CLI.
# cat test1.cli
node srv-a1 utilization capacity="1"
#
Attached "crm_configure_node_for_hb.patch" replaces ID of node (uname)
with UUID, after parsing the node ('node srv-a1 utilization capacity="1"')
command.
# crm -d configure load update test1.cli
(snip)
DEBUG: 1: cli_list: [['node', [['uname', 'srv-a1'], ['id', 'srv-a1']]],
['utilization', [['capacity', '1']]]]
DEBUG: 1: id_replace: <srv-a1> to <0cd9d2df-13fa-4b11-93d3-27a57192caeb>
DEBUG: 1: cli_list: [['node', [['uname', 'srv-a1'], ['id',
'0cd9d2df-13fa-4b11-93d3-27a57192caeb']]], ['utilization', [['capacity', '1']]]]
(snip)
In other words attached patch will get the same result as loading
following cli.
# cat test2.cli
node $id="0cd9d2df-13fa-4b11-93d3-27a57192caeb" utilization capacity="1"
#
Is not this patch effective?

Or is only the crm shell getting it wrong when updating node attributes?
