Hey! I am hoping that someone on here can help me. I am running Ubuntu Server 12.04 LTS with zfs installed. I have a current pool of 1 2TB drive and 1 1TB drive. I would like to mirror that pool to a third 3TB drive. It looks like I should have mirrored the 2TB to the 3TB and then added the 1TB drive? If that is not the case, what is the command that I need to use to add the 3TB drive as a mirror to the existing pool of the 1 and 2 TB drives?
