# 23.2.Linux® 文件系统

FreeBSD 提供了对若干 Linux® 文件系统的内建支持。本节将演示如何加载这些受支持的 Linux® 文件系统的支持，以及如何挂载它们。

## 23.2.1. 扩展文件系统（EXT）

从 FreeBSD 2.2 起，内核便已支持扩展文件系统（EXT）系列文件系统。[ext2fs(5)](https://man.freebsd.org/cgi/man.cgi?query=ext2fs\&sektion=5\&format=html) 驱动允许 FreeBSD 内核对 ext2、ext3 和 ext4 文件系统进行读写操作。

> **警告**
>
> 尚不支持日志功能和加密功能。

要访问 ext 文件系统，可通过指定其 FreeBSD 分区名和一个已存在的挂载点来挂载该 ext 卷。以下示例将 **/dev/ada1s1** 挂载到 **/mnt**：

```sh
# mount -t ext2fs /dev/ada1s1 /mnt
```
