Hey Kory, I think you must mean can you detach one of the 73GB disks from moodle and then add it to another pool of 146GB and you want to save the data from the 73GB disk?
You can't do this and save the data. By using zpool detach, you are removing any knowledge of ZFS from that disk. If you want to save the data from moodle, I would add new disks to this pool, either by replacing the 73GB disks with large disks or by adding another mirror, like this: # zpool replace moodle c1t2d0 c2t2d0 # zpool replace moodle c1t3d0 c2t3d0 or: # zpool add moodle mirror c2t2d0 c2t3d0 Maybe I misunderstand what you are trying to do...
