June 7, 20233 yr Hey there, first time posting and working with Unraid, so be gentle. I just built my first Unraid server. I am on the 6.12 rc7 build cause I just like to live dangerously and it seems stable now. I have 4x 16TB drives that currently going through pre-clear. When they are done, I am curious about ZFS. Do I add the drives to the array and set the type to ZFS? Or do I create a pool specifically for the drives and set type to ZFS for each one? Do I then add the pool to the array, or is the array just not used at that point? Also for cache drives/pool. I have two (1 nvme and 1 ssd) that I wanted to use for cache/vms, etc.. Do I add them to the same pool with 2 drives, or each have their own pool? I assume they don't need to be part of the ZFS pool, or do they? Still learning, much to digest. Thanks!
June 7, 20233 yr Community Expert Either has advantages and disadvantages, main ones are in this post: https://forums.unraid.net/topic/131857-soon™️-612-series/?do=findComment&comment=1243850
June 7, 20233 yr Author Great, that's a good explanation. So the term "Array" probably is going away (from one of the linked posts on that thread). What about the cache drive question? I don't think those would be part of the ZFS pool, but I assume they would be ZFS. Would both disks be in 1 pool, or should I split them up. I don't plan on doing mirroring or Raidz between them - just having two different locations for hi/low speed apps.
