[Cluster-devel] cluster/rgmanager/src/resources samba.metadata ...

[mgrac@sourceware.org <mgrac@sourceware.org>]

CVSROOT:	/cvs/cluster
Module name:	cluster
Changes by:	mgrac at sourceware.org	2006-09-26 23:18:44

Added files:
	rgmanager/src/resources: samba.metadata samba.sh 

Log message:
	Adding Samba resource agent (tag <samba>). We already have resource agent for Samba but this is written in the same way as the other application's RA (mysql, apache, ...). Old-style RA stays available (tag <smb>) so it won't break backward compatibility.
