I am with the Uk storage group slightly ahead of the releases of
LCG as we in the UK try to take the some of the testing strain
for storage solutions and particularly D-Cache and DPM. For example
LCG 1_7_0 will not be using PNFS with the postgresql back end where as most
of the UK D-Cache implementations are all already ahead of the 2_7_0
release in this respect, and are closer to what maybe the bug fix 2_7_1.
I am sorry for adding to the confusion.

I am sorry to have added to the confusion and must seek clarification
myself.
