In case you are interested, I have posted a patch to improve the 'zpool
labelclear' command here :

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204622

- force ('-f') will now allow to erase labels, even if they are broken
(restoring the behaviour of our previous -FreeBSD- version of labelclear)
- You can select which label you want to erase (beginning, end or
specific index)
- You can use a 'minimal' mode which will invalidate a label by changing
only a single byte. This is useful to minimize the chances to
overwrite/destroy a FS that would have been created over the label, but
still leaving the label visible.

Regards,
