Multiple clients accessing git over NFS

  Is it a recommended practice to share a repository over NFS, where
multiple clients can be pushing changes simultaneously?  In our
production environment, we have a Git repository setup behind
git-http-backend. We would like to place multiple Apache servers
behind a load balancer to maximize availability and performance.
Before we proceed, we wanted to check to see if this practice has a
potential to cause repository corruption. If there are other ways
others have solved this problem, we would be very interested in
learning about those as well. Thank you.
