VCN 500 gives the 109100019 error code. The du -h--max-depth=1 command is not recognised after logging in as root to the VCN

The cause of the fault is that the two hard disks are invalid. The status of the hard disk is restored (the number of read and write errors is cleared). You need to check the status of the hard disk periodically and find that the abnormal hard disk is replaced in time to prevent the two hard disks from failing at the same time.
