L2ARC
Daniel Bethe
I got some syntax from a web site, for adding L2ARC to my existing pool which is named 'big'.
hossenfeffer:~ dtm$ zpool add big cache /dev/rdisk0s3
cannot open 'cache': no such device in /dev
must be a full path or shorthand device name
hossenfeffer:~ dtm$
Did I do something wrong or is this impossible? I don't even know if it'd really help; I just had a spare SSD and thought I'd try it.

No, cache device support came out in pool version 10 which is 2 ahead of current MacZFS. I was working on an experimental b77 merge but this had unresolved issues at the time of Z410's announcement and I haven't done any work on it since.

Oh yeah I forgot to look up a list of zpool version features. So I guess maybe 10a286 has it, with its zpool version 11. Oh well, it's not slow anyway and there are different raidz and mirror configurations if a person wants even more speed. I had L2ARC listed in the FAQ as a supported feature, so I just corrected that.
We'll await the appearance of some more source code, then!
