デバイス /dev/mapper/mpathb1 はフィルタによって除外されます。

CentOS 7でmpathデバイスを使用して物理ボリュームを作成しようとしています。しかし、このエラーメッセージが表示されます。

この問題を解決するには？

 pvcreate /dev/mapper/mpathb1

# grep 'filter =' /etc/lvm/lvm.conf |grep -v  "#"
        filter = [ "a|^/dev/sda[1-9]$|", "a|/dev/mapper/.*|" ]

アップデート1：

パーティションを再作成し、lvmフィルタを更新しました。それでも同じエラーが発生します。
