Hello,

You configured a monitor operation for this unmanaged resource?
Yes, and some parts work as expected, however some behaviour is
strange.
Config (relevant part only):
----------------------------
primitive mysql-percona lsb:mysql \
op start enabled="false" interval="0" \
op stop enabled="false" interval="0" \
op monitor enabled="true" timeout="20s" interval="10s" \
meta migration-threshold="2" failure-timeout="30s"
is-managed="false"
clone CLONE-percona mysql-percona \
meta clone-max="2" clone-node-max="1" is-managed="false"
location clone-percona-placement CLONE-percona \
rule $id="clone-percona-placement-rule" -inf: #uname ne NODE1
and #uname ne NODE2
colocation APP-dev2-private-percona-withip inf: IP CLONE-percona
Test:
----
I start by both Percona XtraDB machines running:
IP-dev2-privatevip1 (ocf::heartbeat:IPaddr2): Started
NODE2
Clone Set: CLONE-percona [mysql-percona] (unmanaged)
mysql-percona:0 (lsb:mysql): Started NODE1 (unmanaged)
mysql-percona:1 (lsb:mysql): Started NODE2 (unmanaged)
shell# /etc/init.d/mysql stop on NODE2
... Pacemaker reacts as expected ....
IP-dev2-privatevip1 (ocf::heartbeat:IPaddr2): Started
NODE1
Clone Set: CLONE-percona [mysql-percona] (unmanaged)
mysql-percona:0 (lsb:mysql): Started NODE1 (unmanaged)
mysql-percona:1 (lsb:mysql): Started NODE2 (unmanaged)
FAILED
.. then I wait ....
.. after some time (1 min), the ressource is shown as running ...
IP-dev2-privatevip1 (ocf::heartbeat:IPaddr2): Started
NODE1
Clone Set: CLONE-percona [mysql-percona] (unmanaged)
mysql-percona:0 (lsb:mysql): Started NODE1 (unmanaged)
mysql-percona:1 (lsb:mysql): Started NODE2 (unmanaged)
But it is definitly not running:
shell# /etc/init.d/mysql status
MySQL (Percona XtraDB Cluster) is not running
[FEHLGESCHLAGEN]
When I run probe "crm resource reprobe" it switches to:
IP-dev2-privatevip1 (ocf::heartbeat:IPaddr2): Started
NODE1
Clone Set: CLONE-percona [mysql-percona] (unmanaged)
mysql-percona:0 (lsb:mysql): Started NODE1 (unmanaged)
Stopped: [ mysql-percona:1 ]
Then when I start it again:
/etc/init.d/mysql start on NODE2
It stays this way:
IP-dev2-privatevip1 (ocf::heartbeat:IPaddr2): Started
NODE1
Clone Set: CLONE-percona [mysql-percona] (unmanaged)
mysql-percona:0 (lsb:mysql): Started NODE1 (unmanaged)
Stopped: [ mysql-percona:1 ]
Only a manual "reprobe" helps:
IP-dev2-privatevip1 (ocf::heartbeat:IPaddr2): Started
NODE1
Clone Set: CLONE-percona [mysql-percona] (unmanaged)
mysql-percona:0 (lsb:mysql): Started NODE1 (unmanaged)
mysql-percona:1 (lsb:mysql): Started NODE2 (unmanaged)
Same thing happens when I reboot NODE2 (or other way around).

I would expect that crm_mon ALWAYS reflects the local state, however it
looks like a bug for me.
Any hints whats missing ?
Regards,
Andreas
