What exactly is the purpose of doing a trim? If you are running P3700's for example, does this even need to be done?
Motivation and Context
UNMAP/TRIM support is a frequently-requested feature to help prevent performance from degrading on SSDs and on various other SAN-like storage back-ends. By issuing UNMAP/TRIM commands for sectors which are no longer allocated the underlying device can often more efficiently manage itself.
I tried the trim feature, but it doesn't seem to trim everything?

AFAIK merged patched before 1 Jul. Should be in BETA2....
Dualcontroller HA, relies heavily on the hardware IX uses. It isn't about technical knowhow, it's designed to work only for the IX boxes with dual controllers...I am wondering if it is possible to add Dual Controller HA, I noticed is under the list Enterprise list but, this option even for a home users with enough technical knowledge can be ease to setup and prevent data lost due to hard down on the controller such burn USB, SSD or SD hardware.
I was looking for this feature and happened to run into this thread.

I think for those users SCALE would be a solution that is closer to what they want...@ornias Correct, that is the reason why I was wondering if the DCHA will be mote to FN instead to be close coding for IX TNC. Some home users use enterprise level hardware, for instance a HPE ProLiant DL380 G9 collecting dust for the last couple of years. Opening to support other hardware and setting and active/passive mode sound pretty good to me. But I again, I can see this request is hard to put on the front lines due to the differences between free and enterprise products, not to mention possibly the codding complexity. Kind of a wishlist item if you would.

SCALE is discussed here: https://www.ixsystems.com/community/forums/truenas-scale-discussion/I thought the idea was to make FN more competitive against enterprise level applications.
Right now it seems more of a blockage to progress FN to a more competitive level since iXsystems has their enterprise level to think about.
This is one of the disadvantage of OpenSoure software going under an commercial umbrellas.
Do you have a link to SCALE?

Enterprise-grade is not that easy. The HPE DL380 G9 is a nice server, but it is not a storage system hardware with hot-swap redundant controllers with a reliable, high speed interconnect between them and shared access to all drives. With TrueNAS SCALE, a cluster of servers will be made reliable if configured and managed well.
Sorry, I overly cropped the image. Purple line is ARC. Orange line is L2ARC.
That is exactly the whole idea. For what I have learn about FreeNAS, is that it is no only for enterprise but also for home and SOHO>
I shouldn't have to go and spend on FFA220 or a FAS2240 since those are full feature enterprise level storage with full OC or copper redundant ARRAY access and controllers. I looking at FN from a home storage solution in which part a dual USB controller can, perhaps, be set on a redundant state. The USB bus can, possibly, be used a redundancy to monitor both controllers, in this case, both USB drive.
If I want to go to the enterprise level, I can acquire a FAS3240 controller from eBay for $99 and call it the day.
Since the device already has DATA ONTAP, why would I need FN? Kind of defeat the purpose, don't you think?
another justification for a requested features threadAre you frustrated and complaining about a totally free product?
If it doesn't fit your needs there are other solutions in the marketplace you could buy. I would completely understand your frustration if you had paid for this, and the feature or solution was promised, and then it wasn't delivered. That's not what happened, right?
