[linux-lvm] can't mount vfat fs on lvm created by winxp guest on xen

[Yann Boutin <yann boutin free fr>]

Greetings, 
I've had no success with mounting a vfat file system created by a 
Windows XP guest on a lvm volume. Windows XP guest is running under xen 3.0.5 rc3.

# mount -t vfat /dev/vg1/win1 /mnt/
mount: wrong fs type, bad option, bad superblock on /dev/vg1/win1,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

# dmesg
FAT: invalid media value (0xb9)
VFS: Can't find a valid FAT filesystem on dev dm-0.

# lvm version
  LVM version:     2.02.10 (2006-09-19)
  Library version: 1.02.10 (2006-09-19)
  Driver version:  4.7.0

# uname -a
Linux gentoo 2.6.18-xen #6 SMP Sun Apr 22 12:11:43 CEST 2007 i686 
Intel(R) Core(TM)2 CPU          6300  @ 1.86GHz GenuineIntel GNU/Linux


I found solutions for similar problem (symptoms) reported with usb pens but no one worked.

Help  would be greatly appreciated.

Thanks!
