My current idea (IANAKH) would be that the client is caching the directory and file data and is not notified that anything has changed on disk, so there is no reason to refresh the cached data from disk. The behaviour sounds similar to two FreeBSD-Systems accessing the same disk device via SCSI (without synchronizing disk access). Regards, Holger Kipp
