Do we need this plugin to schedule a TRIM or is this now built into UnRaid?

Searching google for information about this gives me conflicting results.

And is TRIM required in the first place .. for SSD cache?

Yes you need the plugin.

 

And yes, trim is required for SSD's.  Many, many articles about the benefits of trim on the internet

It's not required but it's highly recommended, no trim without it.

Is it okay to run the TRIM plugin once everyday?

Yes

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?

Settings -> Scheduler

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?

Yes, controller need to support it also.

Is there a way to find out if the controller supports it?

Controller and error?

I dont understand why  i get error message that SSD-trim isn't installed and activated when it is???

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

A rescan didn't help. But afterwards i rebooted my server it worked ?

Does this work if your cache drive is an M.2 drive with an XFS file system? or do you have to run BTRFS? I only have one drive, so I set it up as XFS.

Yes

It is 2021.  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.

Is the SSD trim needed for a NVME cache drive? I wasn't sure if a NVME works the same as a SSD....but I suppose it is a type of SSD.

Same answer as above.

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?
