Re: [ogfs-dev]cidev info integrated into superblock

["David B. Zafman" <david.zafman@hp.com>]

What does it mean if I have more than one GFS filesystem?  Do I need 
cidev information at the end of both?  I also view cidev information as 
independent (as part of the cluster infastruction: CI, OCF, ...).  The 
node number/name to journal is the only thing that would seem to me to 
be not only GFS but per filesystem specific.
