Hi everybody!

Due to a electrical cut, my freenas server describe a critical state of my usb key, i tryed to fix this problem without success.
Can anyone describe me how to re install, on a new usb flash disk, WITHOUT losing data.

I understand that there is a upload mode that can makes recover the configuration but i'am afraid to do this without a coaching!

Thanks.

Go here and scroll down to "Should a boot device fail..."

Not losing the data and recovering the configuration are different problems. If the USB stick is still readable you can recover the old configuration. A forum search should yield the answer to where to find it.

EDIT: this is assuming you didn't previously save the configuration. If you did, you can just upload it after reinstalling.
