[Linux-ha-dev] clones, groups and notify

[Serge Dubrouski]

Without a group it works fine. But the trick is that I want to combine
OCFS2, Filesystem and Apache primitives into a group and that
configuration doesn't work. My guess that after adding a group CRM
doesn't call OCFS2 RA with a "notify" command and if I'm right it's
definitely a bug that needs to be fixed.
