Hi guys, After going through encrypting my data drives and moving data back and forth, I'm ready for the next step- cache drive encryption. I have read some discussion on it, including the fact that TRIM is not supported at the dm-layer, so overprovisioning is the only option at the moment.   I currently have the following: 1. 512Gb cache SSD drive with dockers only formatted btrfs 2. Empty 512Gb SSD drive, newly purchased, not added to the config   Desire
