I see. That report seems to indicate that DFS support is required in OpenSolaris's cifs support. I don't know for certain, however, that that is how Windows supports equivalent functionality when e.g. junctions are used on Windows to transparently splice together many separate filesystems into a filesystem graph-shaped view. It is not that one share is nested inside another (possibly from a separate machine), requiring arbitrary nesting & forwarding of smb protocol logic; it is that smb protocol perspective is layered above the filesystem's path translation logic. Or to put it another way, if the cifs service were implemented in userspace, seeing the same local unified filesystem view as every other userspace application, this problem wouldn't exist. It sounds like a layering issue. This fairly radically limits the usefulness of using "lots and lots" of zfs filesystems in a cifs context, unless perhaps I start using samba instead, which I guess does not have the same limitation. I'm disappointed. I'll look into using samba instead. -- Barry -- http://barrkel.blogspot.com/ _______________________________________________ cifs-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/cifs-discuss
