Segmentation fault on FreeNAS 8 boot

[Kiyus]

I've been running FreeNAS 8 for a while now but there was a hard reset (power went out) and now when my system boots it runs into a "segmentation fault".

During boot it displays these lines:

GEOM: da0s1: geometry does not match label (16h,63s != 255h,63s).
GEOM: da0s2: geometry does not match label (16h,63s != 255h,63s).
Trying to mount root from ufs:/dev/ufs/FreeNASs2a
WARMING: / was not properly dismounted
pid 26 (mount), uid 0: exited on signal 11
Segmentation fault
pid 28 (mount), uid 0: exited on signal 11
Segmentation fault
mount -o ro /dev/ufs/FreeNASs3 /conf/default/etc failed: dropping into /bin/sh

What's going on and how do I fix it? Any help would be appreciated.

Thanks

Your USB key is corrupted. Easiest fix is to reinstall FreeNAS and restore the config backup.

Foolishly I don't have a config backup. Is there some way to force mount the drive to get the config settings off of the old usb?

You could try to plug it into a FreeBSD machine/VM and fsck and mount it. The config file is in the 4th partition (da0s4), it's the freenas-v1.db file.

Thank you so much! I managed to salvage my config file and use it on a new OS install.
