Hi,

  I have a Red Hat Virtual Machine running on Oracle Virtual Box.    I want to be able to use all the available space in my hard drive.

  Please help to configure Linux to use all the current space available in the hard drive.

  At the beginning i had a smaller hard drive, i then made a cloning of it to a larger hard drive.  I used VboxManage Clonehd  --existing.., then i was able to reboot the machine with the new hard drive.  But i haven't been able to take advantage of the current space available.  Do not know how to do it in Linux.

you most likely need to extend lvm.

Post the output to
pvs
vgs
lvs

it may just mean extending the lv using lvextend.
