luksFormat wiping raid metadata from end of device?

Asked by ceg

Does luksFormat properly wipe old RAID metadata from end of device?

If it does not, the device will look like a RAID device *containing* luks, and might get set up as such leading to data inconsistency and corruption.

It should probably always wipe the beginnig and end of a divice prior to installing luks metadata.

in a terminal try

dmraid --help
sudo dmraid -s

if there is any metadata present and you need to remove it then

sudo dmraid -rE

should do the trick.

Can you help with this problem?
