I don't exactly know about the internals of clients and server, but
I was just thinking that, as the files are replicated, and as the local
brick would always reply faster than the distant one, maybe for reading,
the local brick would likely be used, thus speeding up acces to the file
compared to distant file access (This is what I can observe from my test
My main concern here is on file locking with using two
different clients. Can this setup work, or this is definitely not
something that can work.
