如果是LVM管理分区的

ls -l /dev/mapper

 

xfs_repair /dev/mapper/cl_muban-root

若提示

xfs_repair -L /dev/mapper/cl_muban-root

最后重启

init 6

 

 

情况2:

[sda] Assuming drive cache: write through

Metadata corruption detected at xfs_agi_read_verify+0x5e/0x110 [xfs], xfs_agi block 0x2

Unmount and run xfs_repair

First 64 bytes of corrupted metadata buffer:

XFS (dm-0):metadata I/O error: block 0x2 ("xfs_trans_read_buf_map") error 117 numblks 1

 

修复步骤:

ls -l /dev/mapper

mkdir /mnt

mount /dev/mapper/cl_muban-root /mnt   # 这里也可以操作 提示中的 dm-0 (即 /dev/dm-0,其实/dev/mapper/cl_muban-root是链接到 /dev/dm-0  )

umount /mnt

xfs_repair /dev/mapper/cl_muban-root   # 或 xfs_repair  /dev/dm-0

init 6 (reboot重启系统)
