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.
pi@raspberry:~/ $ sudo pvcreate /dev/sdb
Device /dev/sda excluded by a filter.
pi@raspberry:~/
Pre-requisites
- sudo access
- In this example, we’ll be using the disk sdb; you’ll want to change it to your disk.
Resolution
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.
