  <p>As you can see the space directory of rhel-root is full so I would like to increase the space of its directory. How can I do it. By the way, this is rhel 7.3.This is the display for vgs and vgsdisplay. Also is it possible to transfer empty space in another directory to the root?(For home directory has 252G of available space so is it possible to transfer some to the root directory?)</p>
