How to Check the Raid 1 Setup On Ubuntu Server

From a terminal window enter the following:

sudo mdadm -D /dev/md0

sudo mdadm -D /dev/md1

The first command checks your Raid Array0 (/dev/md0 — ordinarily an array of your swap volume).

The second command checks your Raid Array1 (/dev/md1 — ordinarily an array of the boot / OS / file and data volume).
