未找到设备 /dev/sdb1（或被过滤忽略）

Question

我正在尝试添加一个物理卷，用于添加卷组，从而在其中添加 LV。可悲的是，我收到以下错误。

[root@server ~]# pvcreate /dev/sdb1
Device /dev/sdb1 not found (or ignored by filtering).

[root@server ~]# fdisk -l /dev/sdb

WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted.

我将不胜感激您能提供的任何帮助。这将是我第一次不得不添加 pv 并且在研究这个问题时我没有遇到任何有很大帮助的东西。

操作系统是 centos 6 - 64 位

过滤器

# By default we accept every block device:
filter = [ "a/.*/" ]

# Exclude the cdrom drive
# filter = [ "r|/dev/cdrom|" ]

# When testing I like to work with just loopback devices:
# filter = [ "a/loop/", "r/.*/" ]

# Or maybe all loops and ide drives except hdc:
# filter =[ "a|loop|", "r|/dev/hdc|", "a|/dev/ide|", "r|.*|" ]

# Use anchors if you want to be really specific
# filter = [ "a|^/dev/hda8$|", "r/.*/" ]

分手：

parted /dev/sdb "unit s" "print"
Model: Adaptec AdaptecRAID5 (scsi)
Disk /dev/sdb: 38996510720s
Sector size (logical/physical): 512B/512B
Partition Table: gpt

MBR 中的分区类型设置为“ ee”意味着磁盘上应该有一个GPT分区表，但如图parted所示，根本没有 GPT 表。

您需要：
a) 使用 parted 创建 GPT 分区，并将该分区用作 PV
b) 完全从 MBR 中删除分区表，仅使用块设备/dev/sdb作为 PV
