Hi Rich, I read this article :- https://inthecloud.readthedocs.org/zh_CN/latest/index.html
and used below set of commands :- Virtual Machine File System expansion <https://translate.googleusercontent.com/translate_c?depth=1&hl=en&prev=/search%3Fq%3Dhttps://inthecloud.readthedocs.org%26biw%3D1440%26bih%3D789&rurl=translate.google.com.hk&sl=zh-CN&u=https://inthecloud.readthedocs.org/zh_CN/latest/posts/ch03.html&usg=ALkJrhiaix6TlqJPXyUpzoTY1kZriRpW3Q#id11> oVirt 3.4 disks can be online expansion, but for the disk within a file system requires a separate support for Linux and Windows lists commonly used method in this expansion. *Linux file system expansion (libguestfs)* For details, please refer to libguestfs site <https://translate.googleusercontent.com/translate_c?depth=1&hl=en&prev=/search%3Fq%3Dhttps://inthecloud.readthedocs.org%26biw%3D1440%26bih%3D789&rurl=translate.google.com.hk&sl=zh-CN&u=http://libguestfs.org/&usg=ALkJrhhw7qzZZdvvvGYkIoGrDbC9DiD_qw> . 1.
