Problems with Disks after power loss

[4things]

Hey,

yesterday our powerline was cut by workers on the street so my server is dead.
After i restartet it it gave the following output:

GEOM: da0s2: geometry does not match label (16h,63s != 255h,63s)

After a short research i figured out to write the filesystem via fdisk like so:

# sysinstall

Go to “Configure”

Go to “Fdisk”

Do “W” (=write) and ignore the Warning

Do not install the bootmanger (choose “Cancel”)

Exit the install

After restarting the machine i get these error:

WARNING: /data was not properly dismounted

I've noticed that there are no backups from the configuration stick. I'm sorry

All in all the Freenas isn't comming up.

What can i do?

Build a new Stick and than is it possible to restore the two mirrors of 4 discs on a new system or is the data lost?

Thank you in advanced for your help

Regards
