The evidence:
[root@localhost ~]# wipefs /dev/sda3
[root@localhost ~]# wipefs /dev/sdb1
offset type
----------------------------------------------------------------
0x218 LVM2_member [raid]
UUID: ZSSjZv-FU0H-Zeaa-92GU-37Zs-KyLS-JMF03Y
[root@localhost ~]# wipefs /dev/sdc1
[root@localhost ~]# wipefs /dev/sdd1
[root@localhost ~]# blkid /dev/sdb1
/dev/sdb1: UUID="ZSSjZv-FU0H-Zeaa-92GU-37Zs-KyLS-JMF03Y" TYPE="LVM2_member"
