How can I mount a non-booting pfSense volume?

[tolistim]

Hi Folks,

Disk failure strikes.  I would like to double check my backups against the last state before the failure.  I can view the disk and its partition table is valid, it just won't boot.

I would like to boot a new install and then mount the old disk.  Can we do this?  If yes, how as a simple "mount /dev/ad0pX" fails with unknown filesystem type.

Thanks,
Tim

Use "-t ufs" on the mount command. You'll probably need to run "fsck -y -t ufs /dev/ad0pX" first.
