# geom\_linux\_lvm.4

`geom_linux_lvm` — 基于 GEOM 的 Linux LVM 逻辑卷映射

## 名称

`geom_linux_lvm`

## 概要

`要将本驱动程序编译进内核，请在你的内核配置文件中加入以下行：`

> options GEOM\_LINUX\_LVM

`或者，要在引导时以模块方式加载该驱动程序，请在 loader.conf(5) 中加入以下行：`

```sh
geom_linux_lvm_load="YES"
```

## 描述

`geom_linux_lvm` 框架提供将 Linux LVM 卷映射到 GEOM 提供程序的支持。`geom_linux_lvm` 目前支持在一个或多个物理磁盘上具有段的线性条带。解析器能够读取 LVM2 文本格式元数据，逻辑卷将被组装并使其在 **/dev/linux\_lvm/** 下可用。元数据是只读的，无法分配或调整逻辑卷的大小。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/geom_linux_lvm.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
