Unrecognised device in blkid output

Question

Unrecognised device **/dev/md0p2**. Possibly from previous trails with raid1 and lvm. It's of type lvm2pv, just like /dev/sda2, which would suggest it's a physical volume for lvm.

But, pvdisplay only displays the /dev/sda2, and not /dev/md0p2. How do I get rid of it properly?
