So if I'm reading right, the setup is nfs client---NFSv3--->knfsd---FUSE-->gluster I hate to just pass the buck, but my bet is on the issue being either on the gluster side, or on limitations of the fuse protocol itself. Cc'ing Miklos as I believe he did the original fuse nfsd export implementation. Miklos, does fuse has a way for file owners to override permissions? We need this sometimes because for example, an application may hold a write open on a read-only file, but the server doesn't itself already have an open (which can happen for lots of reasons). --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
