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

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): [ 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?
