Fixing Error 19 in OPNsense

Error 19 usually shows a problem mounting the disk where we plan to install the operating system. Mounting is the process of making the disk accessible during the set up process.

Possible Causes of the Error

1. The disk used for setup may have underlying issues that avoid correct mounting.

2. The disk may not be properly partitioned for OPNsense setup, resulting in mounting troubles.

3. Errors can occur when the system’s boot mode does not match its setup technique (Legacy or UEFI image).

4. In rare cases, mismatch between the storage controller and OPNsense may result in mounting issues.

Steps to Fix the Error

1. Firstly, look at the OPNsense system logs to find more detailed error messages. We can access these logs through the web interface or by going to /var/log/system.log in the command line.

2. Boot the system in single-user mode or using a live environment.

3. Run the fsck command to check and repair filesystem errors. Replace /dev/sdXn with the correct device identifier:

4. Enter the BIOS/UEFI setup when the system boots.

5. Check the settings related to storage devices and controllers.

6. If unsure, reset to default settings and resetup as needed.

7. Ensure the OPNsense system is fully updated using the web interface or CLI:

8. Install or update any specific drivers needed for the hardware.

9. If a recent config change caused the issue, restore a previous backup of the OPNsense config via the web interface under System > Configuration > Backups.

Other Troubleshooting Tips

1. Check the health of the storage devices. Use smartctl to check for SMART faults on hard drives or SSDs.

2. Replace any defective hardware parts.

3. Boot into a live environment or use OPNsense’s recovery mode to perform filesystem checks and repairs.

4. Check and, if needed, reset the BIOS/UEFI settings to confirm that they are properly created.

5. Check that storage controllers are set to the appropriate mode (for example, AHCI for SATA drives).

6. Make sure all of the vital drivers are up to date. This may include upgrading the OPNsense system or manually setting up certain drivers.

7. Check OPNsense settings for faults or misconfigurations.

8. Consider restoring from a backup if recent changes may have caused the problem.
