[Samba] FAT32 format HDD recognizes as NTFS

[Sallow Yang]

Hi,

The following are my steps:
1. Insert a FAT32 format HDD into usb port of Linux PC.
2. After HDD mounted successfully, configure and start samba to share the
HDD.
3. Using Map Network Drive of Windows XP to map the HDD to a windows network
drive.
4.Open the mapped network drive, can see "NTFS" file system on the left
details.

It shows the wrong info, could anybody help me?
Thanks in advance!!

Samba allows a directory your Linux box to appear to be an NTFS
volume. That is its purpose. It really doesn't matter what the
original filesystem is: you can export an ext3 filesystem, ext4, xfs,
FAT32... whatever the original filesystem is, the Samba clients (for
example your XP machine) will see it as an NTFS volume.

This isn't really all that different (in my opinion) from the way that
NFS will make directories appear as NFS volumes. It didn't matter
what the original filesystem was in that case either.

My theory is that it has to do with the capabilities of the file system.
Samba is presenting a FS that has ownership and permission capabilities,
Windows only knows of one FS that supports those capabilities, therefore
it must be NTFS.

I doubt it has any real effect, it's not like Windows will try to run
chkdsk on it or anything.

The client should really see it as a SMB or CIFS volume rather than NTFS.

I would have said it was closer to exporting an ext3 FS over NFS and the
client reporting that it is reiser.

But I think windows NTFS supports ownership and permission that is different
from the samba's, am I right? How do they correspond?

I don't know if there is any effect or not.

Why samba has this purpose? I think it shows right info that can make user
more clearly.

Is the display error easy to be fixed by samba?

In my opinion the display error is on the windows side. It should not
be guessing what filesystem type a remote server is using.

As John H. Terpstra has already told:
man smb.conf

shows the option "fstype"; its default is NTFS.

Viele Gruesse!

Please refer to the man page for smb.conf. Look up the parameter "fstype".

Please refer to the man page for smb.conf. Look up the parameter "fstype".

fstype (S)

This parameter allows the administrator to configure the string that
specifies the type of filesystem a share is using that is reported by smbd
(8) <http://sepp.oetiker.ch/samba-3.0.23c-to/help/manpages/smbd.8.html> when
a client queries the filesystem type for a share. The default type is
NTFSfor compatibility with Windows NT but this can be changed to other
strings
such as Samba or FAT if required.

Default: *fstype = NTFS *

Example: *fstype = Samba *

When I set fstype = FAT32 in smb.conf, it can show "FAT32" file system in
the Windows side.
It's the right result, thanks John T!!
