is it safe to resize root, on an LVM system, online?

[Rudi Ahlers <Rudi@xxxxxxxxxxx>]

Hi,

One of our servers has a too small root partition on LVM and needs to
be resized. Can / be safely increased online, without a reboot?

[root@zaxen02 ~]# lvscan
  ACTIVE            '/dev/LVM01/root' [4.00 GB] inherit
  ACTIVE            '/dev/LVM01/home' [20.00 GB] inherit
