Does everyone know about lsblk? It is an easy way to see what is going
on with multiple drives + raid + lvm. I just discovered it! What else am
I missing out on?

lsblk

NAME
       lsblk - list block devices

SYNOPSIS
       lsblk [options]

       lsblk [options] device...

DESCRIPTION
       lsblk  lists information about all or the specified block
devices.  The
       lsblk command reads the sysfs filesystem to gather information.

       The command prints all block devices (except RAM disks) in a
tree-like
       format  by  default.   Use  lsblk --help to get a list of all
available
       columns.
