samba - Dec 2006 - Samba <-> Vista RTM interoperability issue

Hi List!

We've run into interesting problem with Samba and Vista.
In short - there's a Samba server sharing NFS connection. What is shared is
the NFS link mounted somewhere in root (say /nfspath) and [homes] which is in
fact /nfspath/some/dir. And the problem is that Vista client can write a file
onto the share using \\sambaserver\homes\dir notation, but cannot do it using
\\sambaserver\nfspath\some\dir notation (which is in fact the same). The reason
noted by Vista - no free space, <size of saved file> more  needed on the
device.
I've tried that on 3.0.22 and 3.0.23d versions - with the same result. Have
someone met that and what could be the reason?

Regards,
Alexander

Hm, after further investigation it turned out that the reason for such behaviour
was autofs' --ghost directories and Vista's default approach: before
writing Vista does QUERY_FS_INFO request regarding FS free space and for
--ghost'ed dirs Samba returns 0... Older versions such as Win2003 and XP do
not do such requests before writing.

Could someone tell me how Samba defines free space on the share as a response
for such request (not sure, maybe such question is more relevant for
samba-technical)? I've tried using usual Linux tools - df and du and it
turned out that df returns 0 while du seems to return the correct value.
