卸载磁盘流程

1.简述lv vg pv

 在Linux中，LV（Logical Volume）、VG（Volume Group）和PV（Physical Volume）是与逻辑卷管理和LVM（Logical Volume Manager）相关的术语，用于管理磁盘分区和逻辑卷的层次结构。以下是它们的区别：
PV（Physical Volume）：
定义：物理卷是硬盘或硬盘分区，它们是LVM存储的基本构建块。每个PV都是实际的物理硬盘或硬盘分区。
用途：PV用于提供磁盘空间，这些空间可以被分配给VG创建逻辑卷。
特点：PV通常包含文件系统、分区表等数据。在创建PV之前，您需要格式化它并将其配置为LVM PV，以便LVM可以识别和使用它。
VG（Volume Group）：
定义：卷组是PV的集合，它们用于汇总物理磁盘或分区的存储空间。VG是LVM中的逻辑单元，可以看作是一个逻辑容器，可以容纳多个PV。
用途：VG允许将多个PV的存储空间合并成一个大的逻辑池，然后从这个池中创建逻辑卷（LV）。
特点：VG具有名称和属性，可以根据需求添加或删除PV。VG的大小是PV的总和，您可以将其用于创建逻辑卷。
LV（Logical Volume）：
定义：逻辑卷是从VG中分配的存储区域，它类似于传统磁盘分区，但具有更灵活的大小和管理。
用途：LV用于创建文件系统、存储数据或提供分区，它们是用户和应用程序直接访问的存储单元。
特点：LV的大小不受物理硬盘的限制，可以根据需要动态调整大小。LV可以轻松地在VG之间移动，从一个VG移到另一个VG。
总结起来，PV是实际的硬盘或硬盘分区，VG是将多个PV组合成一个逻辑存储池的容器，而LV是从VG中分配的逻辑存储区域，用于存储数据或创建文件系统。LVM提供了更灵活的存储管理，使您可以在运行时调整存储空间，而不需要重新分区或重新格式化硬盘。

#从块设备（例如硬盘或分区）上删除文件系统和签名的命令
#这通常在准备重新分区或重新格式化磁盘时使用，以确保磁盘上不包含旧的文件系统或签名，从而避免潜在的冲突或数据丢失。请谨慎使用此命令，因为它会擦除磁盘上的数据。在操作前请务必确保您已备份了重要数据。

#这里是由于ceph-osd 插入磁盘自动拉起造成的
 
 
# wipefs -a /dev/sdc
wipefs 命令用于清除磁盘上的文件系统、分区表或签名等信息，以便重新使用这个磁盘。
-a 选项表示清除所有的签名和文件系统信息
/dev/sdc 是要清除信息的设备路径，这里假设 /dev/sdc 是一个磁盘或分区

	在Linux中，LV（Logical Volume）、VG（Volume Group）和PV（Physical Volume）是与逻辑卷管理和LVM（Logical Volume Manager）相关的术语，用于管理磁盘分区和逻辑卷的层次结构。以下是它们的区别：
	PV（Physical Volume）：
	定义：物理卷是硬盘或硬盘分区，它们是LVM存储的基本构建块。每个PV都是实际的物理硬盘或硬盘分区。
	用途：PV用于提供磁盘空间，这些空间可以被分配给VG创建逻辑卷。
	特点：PV通常包含文件系统、分区表等数据。在创建PV之前，您需要格式化它并将其配置为LVM PV，以便LVM可以识别和使用它。
	VG（Volume Group）：
	定义：卷组是PV的集合，它们用于汇总物理磁盘或分区的存储空间。VG是LVM中的逻辑单元，可以看作是一个逻辑容器，可以容纳多个PV。
	用途：VG允许将多个PV的存储空间合并成一个大的逻辑池，然后从这个池中创建逻辑卷（LV）。
	特点：VG具有名称和属性，可以根据需求添加或删除PV。VG的大小是PV的总和，您可以将其用于创建逻辑卷。
	LV（Logical Volume）：
	定义：逻辑卷是从VG中分配的存储区域，它类似于传统磁盘分区，但具有更灵活的大小和管理。
	用途：LV用于创建文件系统、存储数据或提供分区，它们是用户和应用程序直接访问的存储单元。
	特点：LV的大小不受物理硬盘的限制，可以根据需要动态调整大小。LV可以轻松地在VG之间移动，从一个VG移到另一个VG。
	总结起来，PV是实际的硬盘或硬盘分区，VG是将多个PV组合成一个逻辑存储池的容器，而LV是从VG中分配的逻辑存储区域，用于存储数据或创建文件系统。LVM提供了更灵活的存储管理，使您可以在运行时调整存储空间，而不需要重新分区或重新格式化硬盘。

	#这通常在准备重新分区或重新格式化磁盘时使用，以确保磁盘上不包含旧的文件系统或签名，从而避免潜在的冲突或数据丢失。请谨慎使用此命令，因为它会擦除磁盘上的数据。在操作前请务必确保您已备份了重要数据。
