Hi everyone,
I successfully installed 2.1.3 heartbeat with 0.6.4 pacemaker on a
Gentoo system.
I basically have FileSystem ressources (OCF agent) I share with apache,
vsftp and samba (lsb agent). Due to a low hardening attempt on this
setup, I re-mount FileSystems (first mounted from a third-party NFS
server) with the "bind" and "ro" option which are seen by some of these
services. So, I have 2 types of FS ressources: the NFS "original" ones
and "remount/bind" FS ones.
Ok, first the setup behave exactly as expected (mount order, collocation
constraints, etc).
A problem occurs when the group containing all FS ressources become a
clone type ressource. Even when I set this clone FS group to run only on
one node with only one instance (clone_max=1, clone_node_max=1), the FS
agent can't mount the "remount/bind" ressources. Other NFS "original" FS
are correctly mounted.
I've done tests with an cleaned CIB with only these FS ressources and no
constraint, and still the same problem with "remount/bind" FS ressources.
Thanks for your help if you have an idea on what I should look for. ^^
Here is my ressource.xml, feel free to ask for more information. Only
the beginning is interesting, as it concerns the problematic clone FS group.

So basically, if I get rid of the clone section and leave the rest of
the group "filesystems" untouched, it works like a charm...
