pvcreate Device /dev/sdb excluded by a filter

When creating LVM physical volume with the command “pvcreate”, I got the following error

root@sok1 ~ # pvcreate /dev/sdb
  Device /dev/sdb excluded by a filter.
root@sok1 ~ #

This disk was previously used as a software raid.

To fix the error message, run

wipefs -a /dev/sdX

Example

root@sok1 ~ # pvcreate /dev/sdb
  Device /dev/sdb excluded by a filter.
root@sok1 ~ # wipefs -a /dev/sdb
