[Xen-users] problems mounting HPFS/NTFS domU partition

Hello,

I''m not able to mount a HPFS/NTFS  domU partition.

My system:

dom0 is on a debian (Lenny) machine, using xen-hypervisor-3.2-1-i386 Xen 
Hypervisor.

domU is a Windows XP machine, that works well.
My target is to mount file system domU machine (when domU is not active).

In my domU configuration file I have:
disk = [''phy:/dev/virtual_machines/xp_disk,hda,w'',
''phy:/dev/hda,hdc:cdrom,r'']

My disk''s partitions are:

fdisk -l
/dev/sda6            2678        6375    29704153+  8e  Linux LVM


pvscan

Well, I would mount XP domU machine with a mount, like this:

mount /dev/virtual_machines/xp_disk /mnt/lvm_disk/
mount: you must specify the filesystem type

If I use -t ntfs, I obtain:

mount -t ntfs /dev/virtual_machines/xp_disk /mnt/lvm_disk/
mount: wrong fs type, bad option, bad superblock 
on /dev/mapper/virtual_machines-xp_disk,

Can someone help me?

Re: [Xen-users] problems mounting HPFS/NTFS domU partition

It''s pretty simple!   :)

 On you Xen Debian Lenny:

apt-get install kpartx ntfs-3g
kpartx -a /dev/virtual_machines/xp_disk
ls -l /dev/virtual_machines/xp_disk*

 You will see your partitions from inside your Logical Volume (I suppose you
use LVM) and now mount it:

ntfs-3g /dev/virtual_machines/xp_disk1 /mnt/windows-domu-c

Good luck!
Thiago

Re: [Xen-users] problems mounting HPFS/NTFS domU partition

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

kpartx will create a new block device /dev/mapper/xp_disk1 (note the directory)
After running kpartx above, try mounting that.

Re: [Xen-users] problems mounting HPFS/NTFS domU partition

Yes Fajar,
you''re right!

Thank you very much, I can mount the disk now:

kpartx -a /dev/virtual_machines/xp_disk
mount /dev/mapper/virtual_machines-xp_disk1 /mnt/lvm_disk/

Problem solved!

Nice!!  :-D
Sorry, I forgot kpartx creates it''s files under /dev/mapper...
