ext* file systems must (1) run a FSCK first and (2) cannot be mounted.

$ sudo e2fsck -f /dev/<DEVICE><PARTITION>
$ sudo tune2fs -U $(uuidgen) /dev/<DEVICE><PARTITION>

Actually, all file systems (regardless of type) require to be unmounted first.

FAT* file systems must use the mlabel command and set a 8 digit serial to be used as the UUID.

$ sudo mlabel -N $(uuidgen | head -c8) -i  /dev/<DEVICE><PARTITION> ::
