How to fix LVM Device /dev/sdb excluded by a filter.

When creating a new PV device using a previously partitioned disk, you may see the following error message.

[email protected]:~/ $ sudo pvcreate /dev/sdb
  Device /dev/sda excluded by a filter.
[email protected]:~/



Confirm that you have selected the correct disk.

This is a safety measure in LVM to prevent you from adding a disk that already has a partition table and filesystem.

sudo fdisk -l /dev/sdb

If you are should that you have the correct disk, we have wipe out the old partition table using wipefs.

sudo wipefs -a /dev/sdb

Now, you should be able to create the PV device without issue.
