NFS locking wasn't implemented in 4.4BSD. There is still no implementation in STABLE. If you really need it, you may take a look at Terry's page where an intra-client NFS lock implementation for STABLE could be found: http://people.freebsd.org/~terry/ If you need the above mentioned patches that apply cleanly to RELENG_4, take a look at this: http://www.blackflag.ru/patches/nfs-client-and-server-locking-4.5-STABLE-20020312.diff It works fine in our production environment and was tested under quite a heavy load. However, do not miss that this patch doesn't actually implement lock requests to the server. It only allows for locks being properly held within a single client. That is, locks for the same file on several different STABLE boxes *won't* work. Thus, the word "intra-client" :) Hope this helps.
