在进行pvcreate创建PV时，可能会遇到Device /dev/sdX excluded by a filter报错，一般出现这个错误是在通过parted分区并删除相应的分区信息以后。遇到这种情况有两种解决方法：

1、通过wipefs 指令清理盘信息

1# wipefs -a /dev/sdb
2/dev/sdb: 8 bytes were erased at offset 0x00000200 (gpt): 45 46 49 20 50 41 52 54
3/dev/sdb: 8 bytes were erased at offset 0x13ffffe00 (gpt): 45 46 49 20 50 41 52 54
4/dev/sdb: 2 bytes were erased at offset 0x000001fe (PMBR): 55 aa
5/dev/sdb: calling ioclt to re-read partition table: Success

上面的方法是推荐方法，执行过后再进行分区创建就可以成功了：

1# pvcreate /dev/sdb
2Physical volume "/dev/sdb" successfully created.

2、通过parted重建label卷标

 1[root@servera ~]# parted /dev/vdb
 2GNU Parted 3.2
 3Using /dev/vdb
