"gstripe list" cannot output nothing, since the sysctl output you posted
says a partial GEOM_STRIPE instance is present on the system.
This is bad:

It looks like you created a both a fdisk partition table and a bsdlabel
partition table on the ad3 drive. If so, your data is probably already
corrupted.
ad1 is also strangely partitioned but since it's your first drive in a
stripe this can be acceptable (it will contain the first sectors of the
array, including its partition tables).

This can happen if the metadata on ad3 is corrupted. You'll need to dump
the last sector and inspect it to verify.
