在虚拟机中添加SCSI格式的磁盘做PV时出现如下报错：Device /dev/sdc excluded by a filter.

[root@CentOS8 ~]#pvcreate /dev/sdc
  Device /dev/sdc excluded by a filter.

1.导致问题的原因是添加的磁盘是在另一个虚拟机中新建的，已经有了分区表，现在的虚拟机并不能识别磁盘的分区表，运行parted命令重做分区表，中途需要输入三次命令。

[root@CentOS8 ~]#parted /dev/sdc
GNU Parted 3.2
Using /dev/sdc
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mklabel msdos                                                    
Warning: The existing disk label on /dev/sdc will be destroyed and all data on this disk will be lost.
Do you want to continue?
Yes/No? yes                                                               
(parted) quit                                                             
Information: You may need to update /etc/fstab.

2.再次运行pvcreate，问是否擦除dos签名，输入y，就可以将磁盘创建为PV了。

[root@CentOS8 ~]#pvcreate /dev/sdc
WARNING: dos signature detected on /dev/sdc at offset 510. Wipe it? [y/n]: y
  Wiping dos signature on /dev/sdc.
