I have done that and from what you said years ago I could use btrfs instead as "With v6.8 you need to run trim manually, with v6.9 no need to trim any btrfs pool since it uses the new discard=async mount option," So tried btrfs with rsync replication and that worked but wasted hours trying to find out any info on how to restore from an rsync backup, can only guess more long cmd lines.
So end of story have dumped unraid out of frustration and using the PC with Windows because I know how to use that and backup/restore it with my SSD's that will all auto trim with zero effort. A mod may as well close the thread.
