If you want to confirm what's present on a device, use the blkid or
file commands:
# blkid /dev/sda1
/dev/sda1: UUID="49f9b992-3c68-4b59-a232-e1a3a4482eed" TYPE="ext4" PARTUUID="000298d0-01"
# file -s /dev/sda1
/dev/sda1: Linux rev 1.0 ext4 filesystem data, UUID=49f9b992-3c68-4b59-a232-e1a3a4482eed (needs journal recovery) (extents) (large files) (huge files)
You can also use the wipefs program to manually remove any signature,
and optionally back it up to a file so that it can be restored (it
will also report label offsets as with pvcreate).
Both blkid and wipefs are from util-linux. The file program comes
from the 'file' package on most distros.
Regards,
Bryn.
