[Libguestfs] unknown/unavailable method for expanding the ntfs filesystem

[Jeffrey]

Hello，everyone


    I ran virt-resize(v1.30.4) on my CentOS 7.1 to resize win2008r2 and got the warning message (virt-resize: warning: unknown/unavailable method for expanding the ntfs 
            filesystem on /dev/sda2):


      >/usr/local/libguestfs-1.30.4/run virt-resize --expand /dev/sda2 /images/win2008_src.raw /dev/vg0/win2008_resize_dst
            [   0.0] Examining /images/win2008_src.raw
            virt-resize: warning: unknown/unavailable method for expanding the ntfs 
            filesystem on /dev/sda2
            **********


            Summary of changes:


            /dev/sda1: This partition will be left alone.


            /dev/sda2: This partition will be resized from 19.9G to 49.9G.


            **********
            [   6.0] Setting up initial partition table on /dev/vg0/win2008_resize_dst
            [   6.2] Copying /dev/sda1
            [   6.5] Copying /dev/sda2




    After virt-resize completed its work, obviously the ntfs filesystem on /dev/sda2 has not been resized. I have already installed libguestfs-winsupport-7.2 and I don't know what cause the problem.


    Can someone help me in this issue? Thanks!
