Thank you all that have responded thus far! I’m surprised my top-line question isn't answered yet, given that having an SSD-based ZIL/SLOG for a spinning rust based pool must be very common and well known…like, from a decade ago ;) Here's the questions again: 1) assuming "autotrim=on" should be set for the SSD-based “log” vdev, and yet makes no sense for HDD (spinning rust) based pool, is it expected to set the “autotrim” property for the whole-pool (assuming it’s ignored by the the HDDs that don’t support TRIM) or for just the “log” vdev? 2) assuming it’s best to set "autotrim=on” for just the “log” vdev, why is the command shown in the permalink above failing?
