How to resolve a non-booting Smoothwall appliance
The appliance is not booting
The LCD says "Disk unrepairable"
No HD activity is seen
If you are receiving the error Disk unrepairable, this means a file system error was detected during a routine file system check when the system was booted.

- Once attached to the console you should see the output from the routine
fsckcommand, indicating which partition contains errors (if not try pressing the SHIFT key to wake the display).
- Note the affected partition(s) — usually listed as something similar to
/dev/sda3 or /dev/md3.
- Login with your root password to access the command line.
- Run the following command to check and fix the file system:
fsck -y /dev/<partition_name>
partition_name is affected partition name noted in step 3.
For example, if the error had been reported on
/dev/sda3 you would use the command:
fsck -y /dev/sda3
Alternatively if you are unsure which partition is affected you can try running a check on all partitions but this may take longer:
It will take some time to fully check and fix the file system and you may see warnings as it finds and repairs problems.
Once completed, the system should automatically boot up as normal and you can continue using the system.
fsck is unable to repair the file system contact your Smoothwall representative for assistance.
