[Pacemaker] slapd RA does not start OpenLDAP server after reboot

[Igor Zinovik]

  Hello.

I have a pacemaker cluster with 2 nodes (opensuse 12.1 and 12.2).  On
both nodes slapd does not get started by pacemaker, but it could be started by
launching `systemctl start ldap.service'.

The problem is that something unlinks `/var/run/slapd' directory after
reboot or shutdown, that is why slapd cannot save its pid file and cannot start.
In log i see:
ldap2:~ # grep '/var/run/slapd' /var/log/messages

I looked at slapd source code but did not found that it destroys its
/var/run/slapd,
it only unlinks pid file inside that directory.

/etc/init.d/ldap script manually creates /var/run/slapd directory each time
when start slapd:
ldap1:~ # fgrep SLAPD_PID_DIR /etc/init.d/ldap
SLAPD_PID_DIR="/var/run/slapd/"
        if [ ! -d $SLAPD_PID_DIR ]; then
            mkdir -p $SLAPD_PID_DIR
            chown ldap:ldap $SLAPD_PID_DIR

I fixed slapd startup problem by changing resource agent script:

I would like to ask does somebody in this list suffer from the same problem?

I use following rpm packages:
opensuse 12.1 resource-agents-3.9.2-2.4.1.x86_64
opensuse 12.2 resource-agents-3.9.2-7.1.2.x86_64
