I've configured Samba to work with MC/SG.

I didn't use HP's configuration.  I installed Samba on both nodes,
and used the smb.conf 'include' feature to include a bit of configuration
file from a file in the cluster package, to refer to the share
in the cluster package.  On the node that the cluster package is not
running, samba cannot find the 'included' file of course, but that
doesn't bother Samba.

You then get the clients to connect to the virtual (cluster) ip/name.
This will work if you have Samba listening on all addresses, as is the
default.


Works fine, and you don't need to stop/start Samba when a package
switches, so you don't bother all the other packages which may be
using Samba at the same time.

If you want more info, I'd be happy to oblige.
