So you really do have enough redundancy to be able to handle this scenario, so 
this is software bug. On recent OpenSolaris build you should be able to detach 
one of the devices, and replace second one. Version 14 corresponds to build 
103, and spa_vdev_detach() was changed significantly in build 105 (along with 
other related changes), so those changes are probably not yet available in 
FreeBSD.

Btw, you do not have to upgrade pool immediately along with upgrade to newer 
ZFS version. Now you cannot use upgraded pool on system running older bits.

Ok, i see. I mistakenly thought that v14 is for user/group quotas which means 
build 114, but i was wrong - user/group quotas require version 15.

I do not know for sure, but quick check with google suggests that chances are 
good.
