Looking at the info of that package it says:
System-config-lvm provides a graphical interface to the LVM tools (and related utilities, including fsck and resize2fs) which is good for non-emergency storage administration. It enables you to
manage your logical volume and filesystem configuration with a few mouse clicks, and it prevents potentially- disasterous command-line mistakes such as reducing a logical volume size before
reducing the filesystem contained within that volume.
It talks about a "graphical interface" and "a few mouse clicks". That sounds like I need a graphical desktop for this package. If so.... I cannot use it. I have no graphical stuff on my servers. A ncurses interface is no problem but it seems this tool is not that.
