Attach an new HD as mirror

[Simply]

I'm missing in FREENAS the simple option to attach a mirror drive on an existing stripe.
Example: I started with a simple server with 1 HD as stripe.
After testing I wanted more safety and added an extra HD in the system.
But within FREENAS GUI I see only the option to ADD this HD to the volume...
So I have to use the SHELL with commandos to ATTACH the new HD as mirror....
For me as noob is this not easy...
A can't find this in the manual but I’m sure I overlook it...

You should be able to do this with
# zpool add <pool name> mirror <original device> <mirror device>

I just tried this with the -n option to simulate and it looked like it should be working

You should be able to do this with
# zpool add <pool name> mirror <original device> <mirror device>

Does this actually work the way you think it does? If so I'm a bit surprised.

A much safer way, no adding:

Code:

zpool attach poolname device new_device

Can try anymore. I added my disks with "attach" instead of "add *** mirror".
