[Linux-cluster] Using LABEL in "Device Special File" as a resource

[Tarun Reddy]

Hmmm....

I guess I never tried to edit cluster.xml by hand. On my system at  
least, redhat-config-cluster does not allow the value. I'll try  
editing cluster.xml tomorrow and see if that works. Could  you let me  
know if you can get redhat-config-cluster to accept the LABEL  
designation? Could it possibly be that my LABEL is "/www" (no quotes)?

Thanks,
Tarun
