What if the physical machine cannot be started due to an abnormal power outage? The editor introduces you to a few ways to deal with it.

(1) the error is as follows

(2) enter / run/initramfs to view the detailed error log rdsosreport.txt

It was found that the mount failed when executing the mount / dev/mapper/centos-root / sysroot command

3) execute the mount / dev/mapper/centos-root / sysroot command manually and find the prompt Structureneeds cleaning. Need to clear the structure

(4) when a "mount:Structure needs cleaning" error occurs on the mount hard disk, you can use xfs_repair to repair it.

Solution method

You can use xfs_repair to fix it, but be aware that files in partitions repaired by xfs_repair will be lost, even files that can be properly displayed by du.

Processing steps:

1 、 umount / dev/mapper/centos-root

2. Xfs_repair / dev/mapper/centos-root or xfs_repair / dev/mapper/centos-root-L.

When the execution is successful, the prompt is as follows:

3. Execute: mount / dev/mapper/centos-root / sysroot

It was found that the mount was successful and the Structureneeds cleaning error was no longer prompted.

4. Cancel the mount: umount / dev/mapper/centos-root

5. Shut down the linux virtual machine and restart it, and then the linux virtual machine can start normally.
