Wiping a terminated server
To wipe a now unused server, turn the server off, booting into the SSD (Ubuntu, username and password gigatux) and then
- dd if=/dev/zero of=/dev/sda bs=1M
To get an idea of how far along it is, in another terminal, run
- kill -USR1 <PID of the dd process>
This displays the current progress, not a continually updated one, so it needs to be run again to get the status next time.
