I have a xen DomU running with Windows Server 2003 on a lvm partition has 10GB but i need more.

if a Linux partition, I would do:

# umount
# lvextend -L +10G /dev/<VG>/<LV>
# resize2fs /dev/<VG>/<LV>

but the partition has inside a partition ntfs in other words

with kpartx command i can see

vg-lv1 :  0 20948697 /dev/vg/lv 63

How can resize this?

  • Boot a livecd in a VM that supports expanding NTFS partitions? – Zoredache Jan 14 '13 at 17:50

You have several options:

  1. You can grow NTFS volumes from within Windows using the diskpart command. IIRC this does not work for the system volume, though.
  2. Since you exposed the partition(s) with kpartx you should be able to grow the file system from the Dom0 with something like GParted.
  3. You can use a Live CD (e.g. Parted Magic) as mentioned by @Zoredache.
  • I'll try with a liveCD if this fails – rkmax Jan 14 '13 at 18:09
