Hi,
I'm running Freenas 9.2.1.3 with and ZFS Pool is a stripe over three mirrors:
mirror: 2x 4TB
mirror: 2x 4TB
mirror: 2x 2TB
Now I would like to replace the the "old" 2x 2TB mirror with an 2x 4TB mirror, because I have some trouble with the 2TB disks. In the wiki I found an article about expanding the pool by replacing old disks, but I would like to go a bit safer way as I have enough free ports to add the new disks additonaly.
Am I right, that it should be possible to add the new disks as additional mirror disks to the 2x 2TB mirror so that there is a 4x mirror (2x 2TB 2x4TB) and after the successfull resilvering remove the two smaller disks to get to the final configuration?
Now to the main question: How should I do this the best way?
The GUI seems not to offer an option to add additional mirror disks. As a sidenote I'm using encrypted drives, so that needs to be considered too.
