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
# wipefs -a /dev/sdb
/dev/sdb: 8 bytes were erased at offset 0x00000200 (gpt): 45 46 49 20 50 41 52 54
/dev/sdb: 8 bytes were erased at offset 0x13ffffe00 (gpt): 45 46 49 20 50 41 52 54
/dev/sdb: 2 bytes were erased at offset 0x000001fe (PMBR): 55 aa
/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：
# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created.
2、通过parted重建label卷标
[root@servera ~]# parted /dev/vdb
