Hello,
I'll try for a week to make a cluster with 2 servers for slapd HA.
ldap01 is the master slapd server, ldap02 is a replica server. All is ok
with Debian and /etc/ldap/slapd.conf configuration.
So now I wants if ldap01 fail that ldap02 became master for continue to
add data in ldap database. And if ldap01 failback I wants it became
slave of ldap02 for resync data.
So I'll try this configuration with pacemaker multi-state with this
configuration :
# crm configure show
node ldap01 \
attributes standby="off"
node ldap02 \
attributes standby="off"
primitive LDAP-SERVER ocf:custom:slapd-ms \
op monitor interval="30s"
primitive VIP-1 ocf:heartbeat:IPaddr2 \
params ip="10.0.2.30" broadcast="10.0.2.255" nic="eth0"
cidr_netmask="24" iflabel="VIP1" \
op monitor interval="30s" timeout="20s"
ms MS-LDAP-SERVER LDAP-SERVER \
params config="/etc/ldap/slapd.conf" lsb_script="/etc/init.d/slapd" \
meta clone-max="2" clone-node-max="1" master-max="1"
master-node-max="1" notify="false" target-role="Master"
colocation LDAP-WITH-IP inf: VIP-1 MS-LDAP-SERVER
order LDAP-AFTER-IP inf: VIP-1 MS-LDAP-SERVER
property $id="cib-bootstrap-options" \
dc-version="1.1.7-ee0730e13d124c3d58f00016c3376a1de5323cff" \
cluster-infrastructure="openais" \
expected-quorum-votes="2" \
stonith-enabled="false" \
no-quorum-policy="ignore" \
last-lrm-refresh="1363619724"
I use a ocf slapd-ms script provided by this article :
http://foaa.de/old-blog/2010/10/intro-to-pacemaker-part-2-advanced-topics/trackback/index.html#master-slave-primus-inter-pares
So my problem is that all the deux nodes start as Slaves for
MS-LDAP-SERVER :
