[Pacemaker] Master/Slave Confusion

[Erich Weiler]

Well, I'm trying to get this to work and running into a wall...  I've 
got 3 servers, I want LDAP to run on testvm2 and testvm3.  I've 
configured LDAP on those 2 servers.  Then I configured crm from scratch 
as thus:

configure property stonith-enabled=falseconfigure primitive LDAP-IP 
ocf:heartbeat:IPaddr2 params ip="10.1.1.80" cidr_netmask="16" op monitor 
interval="30s"
configure primitive LDAP lsb:ldap op monitor interval="40s"configure ms 
LDAP-clone LDAP meta master-max="1" master-node-max="1" clone-max="2" 
clone-node-max="1"
configure colocation LDAP-with-IP inf: LDAP-IP LDAP-clone:Master
configure order LDAP-after-IP inf: LDAP-IP:start LDAP-clone:promote

Here's the crm config at the moment:

node testvm1
node testvm2
node testvm3
primitive LDAP lsb:ldap \
         op monitor interval="40s"
primitive LDAP-IP ocf:heartbeat:IPaddr2 \
         params ip="10.1.1.79" cidr_netmask="16" \
         op monitor interval="30s"
ms LDAP-clone LDAP \
         meta master-max="1" master-node-max="1" clone-max="2" 
clone-node-max="1"
colocation LDAP-with-IP inf: LDAP-IP LDAP-clone:Master
order LDAP-after-IP inf: LDAP-IP:start LDAP-clone:promote
property $id="cib-bootstrap-options" \
         dc-version="1.0.5-462f1569a43740667daf7b0f6b521742e9eb8fa7" \
         cluster-infrastructure="openais" \
         expected-quorum-votes="3" \
         stonith-enabled="false"

But when I check status, I see the IP is not started anywhere, LDAP is 
started on testvm2 and testvm3 (like I wanted), but they are both listed 
as slaves:

Current DC: testvm3 - partition with quorum

============

Online: [ testvm3 testvm2 testvm1 ]

Master/Slave Set: LDAP-clone
         Slaves: [ testvm2 testvm3 ]

Failed actions:
     LDAP_monitor_0 (node=(null), call=4, rc=5, status=complete): not 
installed
     LDAP:1_monitor_0 (node=(null), call=5, rc=5, status=complete): not 
installed
[root at testvm3 ~]#

So I guess my 3 questions are:

1: Why isn't one of the LDAP servers being promoted to master?
2: Is the floating IP down because I've specified that it stick to the 
master, but there is no master?
3: I'd like the LDAP master to exist on testvm3 (with the floating IP) 
at all times, only failing to testvm2 if testvm3 goes down, but I'm not 
clear on how to specify a preference for a node to be a master.

The "Failed actions" exist, I'm guessing, because I didn't install an 
ldap server on testvm1, but I don't care about that because I only want 
LDAP to stay on testvm2 and testvm3.

I feel like I'm close but just lack a little understanding.  The docs 
have me almost there but I'm still a bit blurry obviously.  Any help 
much appreciated!!  I think pacemaker will do great things for us if I 
can get it working as expected....
