[Samba] Samba access of FAT32 mounted file system on FreeBSD

[Josh Finlay]

Hi,

Firstly background - 

FreeNAS 0.7.2 (FreeBSD 7.3-RELEASE-p1) 
Samba 3.5.3
1TB disk, 500GB FAT32 (/dev/da1s1) + 500GB NTFS (/dev/da1s4)

Just to clear it up, I'm using FAT32 and NTFS because this is actually a
media center box that functions as an external HDD when plugged into USB.
I'm using it as a storage device because its quite large a disk, but may
from time to time use it as a media center so I need to keep the disk in a
format that it likes for that.

I've configured both the FAT32 and the NTFS slices exactly the same in
smb.conf and the NTFS slice works great, but the FAT32 will mount but no
access to files or even a list of files.

This is my entire config file, skip over what is irrelevant. At this stage
I'm lost and thinking it could be the smallest of mistakes:

============

# End of performance section
unix charset = UTF-8

[Movies]
comment = 500GB NTFS movie storage
path = /mnt/noontec-movies/
writeable = yes
printable = no
veto files = /.snap/
hide dot files = yes

inherit permissions = yes
vfs objects = recycle
recycle:repository = .recycle/%U
recycle:keeptree = yes
recycle:versions = yes
recycle:touch = yes
recycle:directory_mode = 0777
recycle:subdir_mode = 0700

[Storage]
comment = 500GB FAT file storage
path = /mnt/noontec/
writeable = yes
printable = no
veto files = /.snap/
hide dot files = yes
guest ok = yes
inherit permissions = yes
vfs objects = recycle
recycle:repository = .recycle/%U
recycle:keeptree = yes
recycle:versions = yes
recycle:touch = yes
recycle:directory_mode = 0777
recycle:subdir_mode = 0700

My mounts look like this:

/dev/fuse0 on /mnt/noontec-movies (fusefs, local, synchronous)
/dev/da1s1 on /mnt/noontec (msdosfs, local)

(fuse0 due to the ntfs)

I've tried every which way to mount the FAT32 disk, including:

mount_msdosfs -o large=yes,longnames=yes,nowin95=yes -u root -g wheel -m
777 /dev/da1s1 /mnt/noontec
mount_msdosfs -o large=yes,longnames=yes,nowin95=yes -u nobody -g nobody
-m 777 /dev/da1s1 /mnt/noontec

With all the options, with just defaults, etc etc etc. They all work as
expected on the machine, full read/write access however Samba fails to read
from it.

After some config tweaking I've got Samba to give me at least something to
describe an error:

[2010/06/20 10:07:35.431133,  1] smbd/vfs.c:932(check_reduced_name)

When attempting to access the share (ie. smbclient) I get this
information:

Enter root's password:

When trying to access the NTFS share:

Enter root's password:

This has absolutely got me stumped. I've tried and googled for everything
I can think of but to no avail. I've tried in the IRC channel on freenode
but I think it could be a time zone conflict as there wasn't really anyone
active.

Part of me is conflicted on whether this is a Samba issue or a FreeBSD
issue, but considering I have complete functional access (even for the
lowest permission user) to the mount and yet Samba fails to function - I'm
beginning to become convinced it is a Samba issue.

Any advice on this would be greatly appreciated, as I am out of ideas.

Kindest Regards,
