保哥有一台服务器，以前安装的是Windows2016操作系统。近期，业务部署需求发生改变，需要安装rhel7.6。安装完操作系统后，开始挂载剩余的存储空间。创建lv的时候提示：Device /dev/sdb excluded by a filter。
操作步骤
1，查看以前Windows2016服务器下的空闲分区。
[root@gctn-east-p01 ~]# fdisk -l Disk /dev/sdb: 4798.3 GB, 4798283776000 bytes, 9371648000 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 262144 bytes / 1048576 bytes Disk label type: gpt Disk identifier: 58520033-4270-43FF-87E5-CA79567EC17F # Start End Size Type Name 1 34 262177 128M Microsoft reser Microsoft reserved partition Partition 1 does not start on physical sector boundary. 2 264192 9371645951 4.4T Microsoft basic Basic data partition
2，删除该分区/dev/sdb
[root@gctn-east-p01 ~]# fdisk /dev/sdb WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion. Welcome to fdisk (util-linux 2.23.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help): d Partition number (1,2, default 2): Partition 2 is deleted Command (m for help): d Selected partition 1 Partition 1 is deleted Command (m for help): w The partition table has been altered! [root@gctn-east-p01 ~]# pvcreate /dev/sdb Device /dev/sdb excluded by a filter
解决方案
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。
