I have a hundred or so FC6 NFS clients which manipulate a particular directory served by a RHEL4 server. For historical reasons I have my own locking scheme whereby each client takes out the lock before processing the directory, and releases it on completion, but since moving to FC6 I am getting inconsistency problems - entries in the directory change or disappear while a client is processing it. The directory in question is specifically exported, (it's not part of an exported filesystem), and it's mounted 'noac' on the clients. Should the 'noac' attribute guarantee that directory contents are collected from the master and written back to the master rather than being cached locally? And is this done at diropen/dirclose? Cheers, Terry
