I find a few references to SSDs working with TRIM on UNRAID, but nothing recently which would coincide with LSI driver updates. I wonder how many people out there had this working & just don't realize they are no longer supported...
In the mean time I've figured out that I can manually TRIM my HBA bound SSDs by stopping array, removing from chassis & hot plugging to mobo. Then mount with UD, fstrim & return to normally scheduled programming.
The LSI driver is baked in to UNRAID, so is there any advice on where to bring up this issue with the keepers of that code?
