Hi list,

I am facing a very strange issue.
I have setup a postgresql cluster (with streaming repl).
The replication works ok when started manually but the RA seems to never
promote any host where the resource is started.

my config is bellow:
node pp-obm-sgbd.upond.fr
node pp-obm-sgbd2.upond.fr \
attributes pri_pgsql-data-status=DISCONNECT
primitive pri_obm-locator lsb:obm-locator \
params \
op start interval=0s timeout=60s \
op stop interval=0s timeout=60s \
op monitor interval=10s timeout=20s
primitive pri_pgsql pgsql \
params pgctl="/usr/pgsql-9.1/bin/pg_ctl" psql="/usr/pgsql-9.1/bin/psql"
pgdata="/var/lib/pgsql/9.1/data/" node_list="pp-obm-sgbd.upond.fr
pp-obm-sgbd2.upond.fr" repuser=replication rep_mode=sync

rsc_defaults rsc_defaults-options: \

migration-threshold=5

crm_mon shows both hosts as slaves and none is never promoted ever:

Master/Slave Set: ms_pgsql [pri_pgsql]
Slaves: [ pp-obm-sgbd.upond.fr pp-obm-sgbd2.upond.fr ]
Node Attributes:
* Node pp-obm-sgbd.upond.fr:
+ master-pri_pgsql : 1000
+ pri_pgsql-status : HS:alone
+ pri_pgsql-xlog-loc : 000000002D000078
* Node pp-obm-sgbd2.upond.fr:
+ master-pri_pgsql : -INFINITY
+ pri_pgsql-data-status : DISCONNECT
+ pri_pgsql-status : HS:alone
+ pri_pgsql-xlog-loc : 000000002D000000

on the host I am expecting promotion I see when doing cleanups:
Feb 20 20:15:07 pp-obm-sgbd pgsql(pri_pgsql)[30994]: INFO: Master does not
exist.
Feb 20 20:15:07 pp-obm-sgbd pgsql(pri_pgsql)[30994]: INFO: My data status=.

And on the other node I see the following logs that sounds interrseting:
Feb 20 20:16:10 pp-obm-sgbd2 crmd[19626]: notice: print_synapse:
[Action 18]: Pending pseudo op ms_pgsql_promoted_0 on N/A
(priority: 1000000, waiting: 11)
Feb 20 20:16:10 pp-obm-sgbd2 crmd[19626]: notice: print_synapse:
[Action 17]: Pending pseudo op ms_pgsql_promote_0 on N/A
(priority: 0, waiting: 21)

the N/A part seems to tell me the cluster don't know where to promote the
resource but I can't understand why.

bellow are my constraint rules:

pcs constraint show
Location Constraints:
Ordering Constraints:
demote ms_pgsql then stop pri_vip (score:0)
promote ms_pgsql then start pri_vip (score:0) (non-symmetrical)
Colocation Constraints:
pri_vip with ms_pgsql (score:INFINITY) (rsc-role:Started)
(with-rsc-role:Master)

I am now out of ideas so any help is very much appreciated.

Regards.
