Hi pfSense Gurus!

Please help to take out configuration file from corrupted FW's disk.

The error we have

And we use

fsck -fy /

7 or even 10 times, but results are still not good

THE FOLLOWING DISK SECTORS COULD NOT BE READ: 1285441, 1285442, 1285443, 1285444, 1285445, 1285446, 1285447, 1285448,

23874 files, 269701 used, 73385717 free (1525 frags, 9173024 blocks, 0.0% fragmentation)

So, now the goal are take configuration file from pre-failed disk, than change disk to new one, reinstall pfSense and rollup the configuration.

The /cf/conf/config.xml exist and look good.

Any suggestion how to make this from console?
Or the good way would be take disk from machine, manually copying files by using external hdd case and job done ?

Thank You!

Hi,

If fsk can't help you, you have to apply the classic measures : disk recovery.
It starts with : using dedicated programs.
It ends with : have the job done by a specialized company (dono what they could do if it is an SSD).

Also : when yo install pfSense, you were asked to activated the auto config backup. This means that on a Netgate server the latest copy this file exists. What about obtaining this copy ?
Read more about it in the manual.

from console if you are able to get there, mount a usb stick and copy the file ?

Thank You for suggestion. This is ada0 (I mean SATA HDD).

This was a test pfsense server in a LAB environment and we have old backup, but after last backup a lot of important settings was made. I just try to save time and not doing the job twice :)
