(ideally lockd should be in kernel) If I understood the Isilon presentation during EuroBSDCon 2009 correctly FreeBSD 8.0 has an in-kernel lockd. Porting their code might be an option to achieve that.

I have to remove /var/db/statd.status to achieve that. Yes, the locks (held by lockd) are really dropped. statd.status is used by statd; statd is there to tell the clients that the server dropped the locks (e.g. because it rebooted). So with a nfslocking restart, statd will inform clients tha locks got lost, and the clients will relock their files. But if a client has forgotten the lock (because it's down for example, or just because it's buggy) it won't relock it again. -- Manuel Bouyer, LIP6, Universite Paris VI. manuel.bou...@lip6.fr NetBSD: 26 ans d'experience feront toujours la difference --
