How to repair disk failures

If you see a "disk failure" message is any system logs, it might indicate that the FortiAnalyzer-BigData is experiencing hard disk issues. You can try to repair these issues using software methods.

To repair disk failure issues:

1. Access the bootloader of the host that has disk failure symptoms (see Bootloader).
2. From the bootloader, enter sh to enter the shell.

3. In the shell, run xfs_repair to fix the hard disk issue.

   If the problem persists after running the software fix, you might need to replace the hard disk.
