Hi, I'm in need of a little help/information. 

 

I'm looking to set up a back up nas with zfs now that unraid supports zfs.

 

My goal is to do 1 pool, 3 vdevs, 4 disks per with 1 drive parity per vdev. I only have capacity (and a licence) for 12 drives for this box, so I'm using 12x 3.84tb SSDs. Is this even currently possible? I've seen a lot of info on using zfs for cache, but since I'm doing an all ssd nas, i have no use for a cache array. I've also read that ssds don't play well with normal unraid parity, so that's why I'm thinking it's best to avoid doing a normal unraid array. 

 

Any help or info is appreciated. 

 

fwiw my main unraid nas has this same zfs pool setup, but that box has an unlimted license and I put it together back before unraid supported zfs  by using the plugin. (12 drives, 3 vdevs, 4x per vdev, 1 pool) On that machine i have 2x m.2 drives spoofing an unraid array in order to get docker, etc working. I'm hoping to not have to do the same on my backup nas as I don't have the space. 

 

Thanks.

unRAID currently requires at least 1 drive to be configured in the unRAID Array. It can even be a flash drive however it does count against the total drive limit. 

Well that makes me sad, but it's the answer I expected. Thanks for the info. I'll jam a usb drive in there for the array and make magic happen.
