Information on this seems sketchy. I have samba 2.2 on RHEL 2.1. I have two clients (written in Java using a 1.4.2 JDK). The clients try to lock the same file with an exclusive lock. Both clients always succeed, i.e. locking doesn't seem to work. I have oplocks turned off on the share and locking = yes also. Can someone help debug this? Also, if a client managed to get an X lock on a file and the client box failed, when is the lock released? NFS v4 uses a lease mechanism, how does samba release such locks?
