Reset Xsan Serial Numbers

If by any chance you are setting up a Xsan and are getting these errors:

"Error while writing settings (Duplicate registration)"

Then this apparently has nothing to do with the serial number.

The thing to do is then to get rid of the database by entering the command:

rm /etc/systemserialnumbers/xsan

on Metadata controllers as well as on all the clients.
Then reboot all of them and start anew.

This is how I got it working again.

The hint I followed was found here:
