If you used fsync it should write to permanent storage immediately, and it's no longer the OS' problem. If it's not flushing immediately, maybe the mystery is at the filesystem level or even hardware, both of which you didn't provide. When you say 'users' are they looking at the file via NFS or HTTP? if the latter they could be seeing a cached copy (proxy, browser, etc.).
