How to wipe a signature from a disk device on Linux with wipefs command

Posted on in Categories , , , , , , last updated February 27, 2017

I recently decommissioned Debian Linux based nas server and moved disk from my nas server to Linux-powered desktop. However, when I run fdisk command, I am getting the following error:
    /dev/sdb: device contains a valid ‘LVM2_member’ signature; it is strongly recommended to wipe the device with wipefs(8) if this is unexpected, in order to avoid possible collisions
What is a wipefs and how do I use it on Linux?
