Disclaimer: I've just recently started to use gluster, so take this with a grain of salt. AFAIK what you see is expected behaviour and cannot circumvented due to design decisions to keep all sync logic at the client side. The servers don't know about each other and it is the responsibility of the client to track changes to files. Thus you can't operate locally and rely on the server to notify you when things change on other nodes. This design is somewhat unfortunate as the performance with many small files has turned out to be unacceptably slow in our scenario. cheers Paul
