I am reading as much as I can and getting much of it down, but I can use a little reinforcement on what I want to do.
I have FreeNAS-9.3-STABLE-201412091831 running on a server with a G2120 Pentium (3.1ghz) and 8gb ram. My current configuration is three 2TB drives in raidz, and the performance is very solid. I am getting ~100mb/s read and write speed. Right now, I have two 4TB drives in a NAS box - Zyxel NSA320 - mirrored in a raid 1 configuration, and its performance is acceptable for a home NAS but nowhere near the FreeNAS server. I'd like to just pull these and add them to my server. I do not have the option of purchasing any new drives for a month or two.
Can I add a new vdev with the two 4tb drives in a mirrored array, thus adding ~4tb to my current zpool? I would have two vdevs - the current raidz with the three 2tb drives, and a second vdev with the two 4tb drives mirrored. Would this zpool then stripe across the two vdevs, giving me almost 8tb of available space?
Will this work? If not, what other suggestions do you have? Is it an option partitioning the two 4tb drives and making a 5 drive Raidz2, and if so, can the remaining partitions be used for anything?
Thanks!
