Operation not permitted, when trying to wipe ZFS devices

[Knogle]

Ahoy friends.
Currently i have been using a Fedora system, using a FreeBSD VM to manage the hard drives using ZFS.
Now i have wiped everything and installed FreeNAS, the newly created pool looks fine.
But now i wanted to replace a hard disk, because the previous one failed, there was also a ZFS FS on it before.
So when i try to replace the disk, in order to wipe the new one, and include it into the pool, it says "Operation not permitted" and something with "dd".
Is there a way in order to get it working easily? I only found a quite complicated way.

"Operation not permitted" when trying to wipe disks

tl;dr: How can I wipe a disk? I'm running FreeNAS 11.1-u5, I imported the config from another FreeNAS install that was attached to another volume so as to get all of the previously configured users and groups and I'm trying to setup a new mirrored ZVOL with two 1TB disks that I had previously...

I hope someone could help, because i often have to wipe hard disks, so it should be some solution for everyday use.

I have re-used disks from existing zfs pools and haven't had the issue you describe. as stated in the post you linked you could go through and zero out those blocks. If you could perhaps include screenshots and the steps you are taking.
