我将SSD添加到另一服务器中，但是，当我尝试访问基于dm-crypt的旧磁盘时，出现以下错误：

Reading all physical volumes. This may take a while... 
WARNING: Duplicate VG name server01: Existing bc7YA8-eEXt-1aA1-OHTr-zJkA-ucd0-DsbRTc (created here) takes precedence over RIKiar-w3MG-Gzh5-VFWq-bkRT-9IFc-ia8k87 
WARNING: Duplicate VG name server01: Existing bc7YA8-eEXt-1aA1-OHTr-zJkA-ucd0-DsbRTc (created here) takes precedence over RIKiar-w3MG-Gzh5-VFWq-bkRT-9IFc-ia8k87 
Found volume group "server01" using metadata type lvm2 
Found volume group "server01" using metadata type lvm2 

问题是我的卷组。我在新旧硬盘上都设置为server01。
如何重命名旧的LVM2？如何访问旧硬盘？

dm-crypt是Linux内核v2.6 +及更高版本中的透明磁盘加密子系统。它可以加密整个磁盘，可移动媒体，分区，软件RAID卷，逻辑卷和文件。

解决方案

使用cryptsetup命令打开设备，执行：

# cryptsetup luksOpen /dev/sdXY your-name-here

您需要运行vgdisplay命令以获取有关LVM2卷组的确切信息。
以超级用户身份执行以下命令：

# vgdisplay

输出示例：

记下旧LVM2卷的VG UUID，并使用以下命令将其重命名。
语法为：

vgrename VG-UUID-HERE new-name-here

在此示例中，将具有UUID RIKiar-w3MG-Gzh5-VFWq-bkRT-9IFc-ia8k87的卷重命名为oldharddisk，执行：

# vgrename RIKiar-w3MG-Gzh5-VFWq-bkRT-9IFc-ia8k87 oldharddisk

输出示例：

  Volume group "server01" successfully renamed to "oldharddisk"

您需要扫描所有磁盘上的卷组并重建缓存：

# vgscan --mknodes

输出示例：

Reading all physical volumes.  This Jan take a while...
  Found volume group "oldharddisk" using metadata type lvm2
  Found volume group "server01" using metadata type lvm2

接下来，激活系统中所有已知的卷组，执行：

# vgchange -ay

输出示例：

2 logical volume(s) in volume group "oldharddisk" now active
  3 logical volume(s) in volume group "server01" now active

要查看映射名称，请使用以下命令：

# ls -l /dev/mapper/oldharddisk-*

输出示例：

lrwxrwxrwx 1 root root 7 Jan  5 16:56 /dev/mapper/oldharddisk-root -> ../dm-5
lrwxrwxrwx 1 root root 7 Jan  5 16:56 /dev/mapper/oldharddisk-swap_1 -> ../dm-6

要挂载/dev/mapper/oldharddisk-root，请执行：

# mkdir -p /mnt/oldharddisk
# mount /dev/mapper/oldharddisk-root /mnt/oldharddisk
# df -H

现在，您可以从/mnt/oldharddisk上安装的旧硬盘复制或者还原数据：

# cd /mnt/oldharddisk
# rsync -avrP home/* /home/
