UUID is a globally unique identifier. The UUID in the hard disk partition can guarantee that it can still be loaded correctly when a new partition is added to the hard disk or the partition order is changed. However, when the UUID of the partition changes or the partition is deleted, it may cause the linux to fail to start. The partition is deleted. Generally delete or comment on the corresponding item in / etc/fstab.

The following demonstrates how the UUID of the partition has been changed:

OS:centos 6.6

Operating system Startup report:

Fsck.ext4: Unable to reslve 'UUID=9d51182c-265a-44d3-b29f-294caf780487'

Solution 1:

1. In Give root password for maintenance

(or type Control-D to continue): enter the password to log in.

two。 Mount the root directory as read-write mount-o remount rw /

3.vi / etc/fstab check the file directory of mount corresponding to the UUID that reported an error

a. If you don't know the actual partition corresponding to the file directory, note # the line of UUID that reported an error, wait for the system to start normally, and then use commands such as fdisk,df to find the actual partition and change it.

b. If you know the actual partition corresponding to the file directory, you can directly replace UUID=9d51182c-265a-44d3-b29f-294caf780487 with the actual partition, such as / dev/sda1.

Or use blkid / dev/sda1 to view the current UUID of the partition and change it to the current UUID.

4. Restart reboot

Solution 2:

1. In Give root password for maintenance

(or type Control-D to continue): enter the password to log in.

two。 Mount the root directory as read-write mount-o remount rw /

3. Modify the read and write permissions of / etc/fstab file chmod a+rw / etc/fstab

3. If the mount-o remount rw /, chmod a+rw / etc/fstab,/etc/fstab still cannot be modified, then modify the UUID of the partition

For example: blkid / dev/sda1 # View the UUID of the partition

Tune2fs-U 9d51182c-265a-44d3-b29f-294caf780487 / dev/sda1 # modified to be the same UUID as in / etc/fstab

4. Restart reboot
