Re: FSFS on NFS in a load balanced setup

I am using two identical servers running RHEL4 + Apache + SVN 1.4.3. They
are both mapped to svn.mydomain.com which allows our DNS server to do a
crude round-robin load sharing. From these servers, we serve 4
repositories, all on NFS shares. We have around 50 users accessing the
projects this way. No problems so far...
