I've created a cloud drive, included it to the pool, and used File Placement to make all files in a certain folder be stored on the cloud drive. I've installed and configured the SSD Optimizer plugin, but whenever I copy a file to this folder on the pool, the files are not stored on the SSD, but instead stored on one of my mechanical drives (not marked as SSD, of course). However, the files do get moved to my Cloud drive once the balancer runs.
Any pointers?
