| Hi all.
|
| I have recently introduced two 5.5TB XFS filesystems to our storage
| backend.  I export the filesystem via samba 3.0.3 on Fedora core 2.
| Linux clients that mount the share show only 2TB available.  Windows
| clients show the full capacity.  Before I put these filesystems into
| production I'd like to find out if the reported filesystem size is going
| to cause a problem.  Is SMB actually limited to 2TB?  If so, why do
| Windows clients see the full capacity?  Is this a limitation of the
| samba client software on the linux side?

Well, only if you are using samba client software (ie smbclient, but
*not* smbmount or mount.cifs).

Are you smbmount'ing the share? If so, this may be a limitation in the
smbfs filesystem driver in the kernel. You may want to try using the
cifs driver (mounting with mount.cifs which is part of samba), which is
available in the 2.4 kernels of some distros (ie Mandrake 9.2 and
later), and 2.6 kernels for others.

Regards,
Buchan
