I originally added a pair of samsung 850 Evo's in a mirror, thinking it would help my home media server, before I realized it sits pretty much idle (watching zilstat):
[root@vega] /mnt/lyra/Images# zilstat -M

So i want to remove it... I'm on the latest version of freenas 9.10 something, so am I correct in thinking that I can just do zpool remove lyra mirror-2? Lookign at this post:
https://forums.freenas.org/index.ph...remove-an-ssd-cache-drive-from-a-zpool.22484/
It seems I can, but want to make sure before I run something potentially dangerous against my pool. Thanks!
