The v1 style configuration, the one described in that article, doesn't really support such master-slave configurations. It is possible though with some extra effort on the part of the resource agent to simulate it (that's how it is done in the article). Also, as you noticed, the slave ldap server must be started by hand after the Heartbeat start. > If I configure haresources as: > > Masternode 1.2.3.vip ldap > Slavenode 1.2.3.vip ldap That is not supported. > Both nodes seem to contend for the vip. > > I was thinking I could do: > > Masternode 1.2.3.vip ldap > Slavenode 1.2.3.realip ldap Neither is this. > But I assume in that situation, if the slavenode failed, the masternode > would attempt to take the slavenode real ip as a vip. > > I'm sure I'm overlooking something simple.

Right, crm would be the way to go if you want to have native support for master-slave resources. With v1 it's not impossible, but you'll need to pay attention to how failbacks are handled. BTW, this is not exactly a simple setup. The complexity is in the management of the ldap database. I think that it was already discussed on the list.
