I have SAMBA 2.0.7 running in a 3-way ServiceGuard Cluster (HP-UX 11.0)...
Using SAMBA's "include file = ", I'm able to run a total of 24 different
"samba" servers on just 3 machines; none of them are sitting idle.
It's just a matter of having the right "interfaces =" line in your smb.conf
at the right time, which can be easily modified when starting/stopping your
HA packages.
Did it by creating a simple "add_pkg_to_samba/remove_pkg_from_samba" shell
script that modifies smb.conf when called from HA control scripts (there are
some considerations you need to keep in mind: locking files, necessary clean-up
before joining the cluster after a crash, etc.).
I wish I could share them with you but, unfortunately I can't; they're Motorola
Proprietary.
