Branch: 	RHEL5
Changes by:	rmccabe sourceware org	2007-03-15 22:11:28

Modified files:
	luci/cluster   : resource-form-macros resource_form_handlers.js 
	luci/site/luci/Extensions: ModelBuilder.py TagObject.py 
	                           cluster_adapters.py 

Log message:
	Make the fsid field optional for fs and clusterfs resources. If the user provides nothing, an invalid id, or a duplicate, generate a unique fsid.
