When extending a pool should the new vdevs match exactly the existing vdevs? I keep seeing somewhat conflicting answers to this.
I've been using 6 disk raidz2 vdevs and I setup one pool per vdev for a max of 4 pools per 24 bay case.
I want to move away from this and create a single pool for all the vdevs.
I liked that a vdev could die and I would only lose that vdevs data but balancing the free space was getting silly as they filled up and now that I'm on 10Gbit I am bottle necking on a 6 disk z2.
I want to keep the same 6 disk z2 vdevs since I like that amount of redundancy/it fits the case nicely/buying 8 or 12 disks at a time is too $$.
I have 12x 8tb WD RED and 6x 6tb HGST NAS.
I would like to make 3x 6 disk z2 vdevs out of that (6x 8tb, 6x 8tb, 6x 6tb) and put that all under one pool. Is this a valid setup or is mixing the 6tb drives in no good?
In the near future I want to extend this with another 6 disk z2 for a total of 24 drives, 4 vdevs, 1 pool.
Secondary question, when extending a pool with a new vdev and the pool already has lots of existing data , does it make sense to copy everything to backup and then rewrite it to the pool to get all the data striped evenly across the drives?
