Hello, i'm looking to upgrade my home NAS, my current is about a year or two old...it's running linux 2.6 and using mdadm software raid. When looking to upgrade i've been drawn to ZFS and now that i've been using ZFS in freebsd that is the route i want to go.
My question is this: Is there really a problem with using more than 9 vdevs in a raidz setup? and/or is there a way to separate them into smaller groups but still have them all in the same pool?
I was looking at going with 12 1 tb hard drives in raidz. 11+1 spare. The case i have is upgradeable to 20 drives leaving me room for 8 more which i eventually planned to use. If i did smaller raidz settups like 9+1 spare x2 they would be in separate pools. Would it be possible to somehow POOL that into 1 large pool or is that just a terrible idea?
or can i run 19+1 or 18+2 without much trouble?
