Dynamix SSD Trim needed?

I've never ran Trim on my SSD cache, so I installed the Dynamix SSD Trim plugin. However when I go to the Apps tab, the "Settings" button in disabled.  How do I run it? Can I run it manually, and if so, do I need to stop the array first?

Are you guys absolutely sure that a scheduled ssd trim is still necessary on an BRTFS formatted cache ssd with 6.3.3 ? I ask because there are some errors in my log after such a trim operation on a brtfs cache drive. Maybe it is not even safe to use the ssd trim plugin on such a drive?

Did you originally get the warning and then install and the warning is still there? Hit rescan if that's the case

Do we still need Dynamix TRIM for SSD's?

With v6.9 it's not needed for any cache device or pool using btrfs, still needed for xfs.

Does 6.9 come with Trim support baked in for btrfs?

It uses the new discard=async btrfs mount option.

I just did a quick read on the first Google result for this.  Should we be updating our existing cache pools to use this new feature in place of the SSD TRIM plugin?  Not sure if this was available in beta/RC for others to chime in.

No need to update the pools, you just need to update Unraid to v6.9, after that you can disable the TRIM plugin (if all the pool are btrfs), it won't break anything to leave it installed though.

Would this allow us to connect SSDs to a HBA Controller that doesn't support TRIM now?
