Hi Shrikant,

Guess your question was related to the importance and need of the CFS
primary node. AFAIK, the primary node used to be the only node allowed
to do metadata transactions earlier. But in CFS 5.0, this behaviour
was changed wrt FS v7 and now all nodes can do metadata transactions.
Of course, proper locks are maintained so that the file system is
consistent.

Regards,
Sharninder
