I have not personally tried it. But there was previous discussion
about this on the list, and I was led to understand that a SAN with a
cluster filesystem, such as Apple's Xsan, would adequately insulate
the various repository servers from one another so that they would
not clobber the repositories served on the SAN. I am not familiar
with GFS so I don't know whether it's a cluster filesystem or how it
compares to Xsan.
