Hello,
thanks very much for your replay Thiago.
Yes, I use LVM, but the solution
it isn't so simple...
;-)
I just used ntfs-3g without success...
I just have the link created with kpartx:
ll /dev/virtual_machines/xp_disk
lrwxrwxrwx 1 root root 36 2009-01-28
08:12 /dev/virtual_machines/xp_disk -> /dev/mapper/virtual_machines-xp_disk
but I follow anyway yours instructions:
kpartx -a /dev/virtual_machines/xp_disk
ls -l /dev/virtual_machines/xp_disk*
lrwxrwxrwx 1 root root 36 2009-01-28
08:12 /dev/virtual_machines/xp_disk -> /dev/mapper/virtual_machines-xp_disk
ntfs-3g /dev/virtual_machines/xp_disk1 /mnt/lvm_disk/
ntfs-3g: Failed to access volume '/dev/virtual_machines/xp_disk1': No such
file or directory
Please type 'ntfs-3g --help' for more information.
I think that ntfs-3g isn't able to see /dev/virtual_machines/xp_disk1
infact at filesystem level there is only this file:
/dev/virtual_machines/xp_disk
but if I use /dev/virtual_machines/xp_disk1 this is the output:
ntfs-3g /dev/virtual_machines/xp_disk /mnt/lvm_disk/
NTFS signature is missing.
Failed to mount '/dev/mapper/virtual_machines-xp_disk': Invalid argument
The device '/dev/mapper/virtual_machines-xp_disk' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
I can see the /dev/virtual_machines/xp_disk1
using
sfdisk -l -Us /dev/virtual_machines/xp_disk
(as I show in my first mail)
I saw into mailing list's archives that it is possible to mount NTFS
partitions as shown at this URL:
http://xen.markmail.org/message/pp55m3i77yjskwrz?q=HPFS/NTFS+mount+loop
in particular:
mount -o loop,ro,offset=$(( 512*63 )) /dev/xendata/volume3 /mnt/windows/
I don't know if I can solve my problem using some "mount" options like this
example...
Any help will be appreciated...
Thanks in advance,
Severino Rivadossi
