You don't convert it back, you simply use it as a raw device, but know
that part of the raw device will be corrupt as you have overwitten
certain blocks with the filesystem's superblocks.
To use a partition as a raw device,
- add it to /etc/sysconfig/rawdevices e.g., by adding the line
/dev/raw/raw1 /dev/mapper/mpath0
- and restart the rawdevices service:
service rawdevices restart
Kind regards,
Herta
