Ok. To summarize this somewhat all over the place thread. Lots of thinking out loud, and trying to figure out a future state plan while maximizing the drives I already own.
I have 12 3TB drives right now. And I have 4 3TB drives to help out the migration process (these 4 will not be in the server, but they will help me augment my migration).
Currently, my plan if it makes sense... Is to run 2 vdevs, each with 9x3TB in Z2. I know this is only 22% redundancy, but that data isn't mission critical. Is this not safe? I know cyberjock has a 10x6TB array, but I also know he has extensive knowledge of ZFS and freenas where I do not. That being said, I plan to follow every guide I can find and setup smart monitoring, email notification, literally everything I can to have a full view of my drives health. Also, if I do lose a drive, I plan to shut down the server until a new one is acquired and in my physical possession to swap out the bad drive, so the server will never be running in a degraded state (except during the rebuild.... Obviously).
My next concern is mixing drives. I am current using seagate drives, if I could do it over I would probably go WD greens, but obviously I can't go back in time... Yet ;)
Would it be a bad plan to mix and match seagate 7200 drives and WD greens? Besides the entire vdev being brought down to the slower speed, is there an issue with this? Speed is not a concern, this Will saturate gigabit which is all I require. I just don't want unneeded wear on the drives trying to keep up or slow down to match the other drives.
Thanks for all the help guys!
