Hey list,

I have a machine running ZFS on root. It stopped responding this morning, and upon a reboot, it was unable to mount root from zfs:zroot. It gave the explanation of "error 5."

I played with the mount prompt briefly, but didn't get anywhere. Any tips for diagnosing and fixing the problem?

Thanks!
