本文指导如何通过命令行修复Linux系统中的根分区故障，包括使用`mount`和`fsck`命令定位分区，使用`fsck`修复boot分区和根分区，以及最后重启系统确保修复生效。

部署运行你感兴趣的模型镜像

1。输入命令，查找root所在分区是多少：

mount |grep "on"

2. 然后用命令fsck修复

fsck-y /dev/sda2(root所在分区）

注：-y 选项指定检测每个文件是自动输入yes

3。fsck修复boot分区

fsck -y/dev/sda1

3。reboot重启ok

fsck.ext4 [-panyrcdfvtDFV] [-b superblock] [-B blocksize]
               [-I inode_buffer_blocks] [-P process_inode_size]
               [-l|-L bad_blocks_file] [-C fd] [-j external_journal]
               [-E extended-options] device

Emergency help:
-p                  Automatic repair (no questions)
-n                  Make no changes to the filesystem
-y                  Assume "yes" to all questions
-c                  Check for bad blocks and add them to the badblock list
-f                  Force checking even if filesystem is marked clean
-v                  Be verbose
-bsuperblock       Use alternative superblock
-Bblocksize        Force blocksize when looking for superblock
-j external_journal Setlocation of the external journal
-lbad_blocks_file   Add tobadblocks list
-Lbad_blocks_file   Set badblockslist
