Hi all,

I was testing recovery scenario by removing one of the drives in a 2-way
mirror, but the system fails to boot and comes up with the mountroot prompt
with error 2. When I reconnect the second drive, it boots fine again.

Any suggestions on what the problem might be?

it's a simple root-on-ZFS setup (9.1 upgraded to 10.1 recently) with two
disks in mirror config.
each disk has 3 partitions, first one has the boot code, second has the
swap, third has the OS.

and the zfs pool is setup on the 3rd partition of the two disks.

Kind regards,
Yudi
