Versions - of Samba before 2.2 have tried to use the native - fcntl() unix system call to implement proper record - locking between different Samba clients.

The unix locking only supports byte ranges up to - 2^31. So it is not possible to correctly satisfy a - lock request above 2^31.

All other locks - can not be seen by unix anyway.</para> - - <para>Strictly a SMB server should check for locks before - every read and write call on a file. Unfortunately with the - way fcntl() works this can be slow and may overstress the - rpc.lockd. It is also almost always unnecessary as clients - are supposed to independently make locking calls before reads - and writes anyway if locking is important to them. By default - Samba only makes locking calls when explicitly asked - to by a client, but if you set "strict locking = yes" then it will - make lock checking calls on every read and write. </para> - - <para>You can also disable by range locking completely - using "locking = no".
