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:
- Access the bootloader of the host that has disk failure symptoms (see Bootloader).
- From the bootloader, enter
sh
to enter the shell. - In the shell, run
xfs_repair
to fix the hard disk issue.
If the problem persists after running the software fix, you may need to replace the hard disk.
