I'm in the process of setting up my first FreeNAS server. I've been playing around with it for a few days and getting familiar with the terminology. I've read through the manual and done some searching online, but I cannot find the answer to my question.
Currently, my new server will consist of 5x1.5TB drives and 5x1.0TB drives. My intention is to have 2 vdevs for each of the 2 drive sizes on a RAIDZ1(vdev1 for the 1.5TB drives and vdev2 for the 1TB drives). Total capacity will be 6TB 4TB for a total of 10TB in the pool. I'm using spare drives, otherwise I would be choosing something a little more consistent.
Overall, I'll be protected by one hard drive failure in each vdev. Now pretend that 6 months from now I decide that I want to replace the 1.5TB drives with 4TB drives and remove the 1TB drives completely. Is there a way to replace all of the drive in vdev1 then somehow "retire" the vdev2 drives so that the data they contain will be pushed back to vdev1? Or am I in a situation where I will always have to have 10 drives in the zpool. Obviously, I could create a new zpool, copy all of the data to the new zpool, then remove the old zpool. I was just hoping for simplicity I could avoid it.
Thanks!
