You have completely lost me at this point. You were rather condescending and not helpful. I was hoping for instructions on how to clean and scrub and saw none of that. At least point me to some proper links. I also don't know what a 4k drive is.
I carefully followed and read ALL the instructions and FAQ and Getting Started guide on maczfs.org. Please don't speak to me like I didn't do my research or follow the proper instructions. - James On Tue, May 20, 2014 at 9:24 AM, Jason Belec <jasonbe...@belecmartin.com> wrote: > OK, one thing, any indexing under that version of ZFS is going to kill > performance.
