CTDB is in PARTIALLYONLINE state if at least one of the configured
interfaces is up and one or more configured interfaces are down.

You need to enable PARTIALLYONLINE feature by setting
CTDB_PARTIALLY_ONLINE_INTERFACES="yes" in CTDB configuration
(/etc/sysconfig/ctdb or /etc/ctdb/ctdbd.conf). Assuming you have two
interfaces for hosting public IPs e.g. eth1 and eth2, then marking eth1 up
and eth2 down would create partially online state.
