Replacing boot device

[amnixed]

Hello,

My boot device has failed.

The system was installed with FreeNAS-9.3. It has 4 hard drives: 1 old WD IDE drive (FreeNAS, ada0) and 3 Hitachi SATA drives configured as a 3-way mirror (ada1, ada2, ada3).

I have reinstalled FreeNAS-9.3 on another old hard drive (as a temporary measure) and tried to boot the system with the newly installed boot device.

However, I'm getting these worrying messages:

Code:

GEOM_MIRROR: Cancelling unmapped because of ada0.
GEOM: mirror/gm0: corrupt or invalid GPT detected.
GEOM: mirror/gm0: GPT rejected -- may not be recoverable.
Mounting from zfs:freenas-boot/ROOT/default failed with error 2.

Then I get the mountroot prompt.

Is there a way to get my system boot?

Thanks for any advice...

Do you get the same error if you reinstall the same version to a USB stick?

Hello Dru,

I could successfully reinstall FreeNAS-9.3 on a USB stick - thank you for the hint!

My saved config is apparently too new for the installed system, I'm upgrading to 9.10 now, fingers crossed...

Why would an old but perfectly working hard drive not work though? I dd-d it first.
