[Samba] Questions about file system support in Samba

[Hibbard Smith]

I tried to access these shares from Windows XP Pro SP2 and got identical
results.  Ext3 filesystems smaller than 2 GB work fine.  Anything bigger
than 2 GB and xfs filesystems of any size fails. 

I guess I'm going to have to resort to reading code, posting on bugzilla as
a bug and maybe switching to a Windows based server.  I really need to get
this system up and doing its intended job.

I'd really like to hear from someone that they are actually exporting ext3
filesystems larger than 2 GB and xfs filesystems and it's working.  If
they're doing so with the Fedora core 4 release, that would definitely point
to something strange here.
