    @sbeebe IIRC @riposte is EOL, so, not gonna happen I’m afraid. Sad to see adn rot away.

      @ferebee but thought through by persons who actually take apart things in a regular basis. I’m quite happy with it.

        @ferebee I’m afraid I can’t spare the Time to completely take IT apart at the Moment. I’ll see if I get to it. I got an iFixIt set which also includes Pentalobes, T, ST, etc. sells through their iFixIt Europe store. Quality is fine. Nothing super fancy,

          @ferebee Need to pry open the bottom with a plastic tool. No more twist and pop off. Bottom ESD shielding mounted with ST7. Screams keep out. :-) Apple still sells Fusion drives, so likely possible. Can’t compare to an HDD equipped mini. Image [photos.app.net]

            @ferebee Ripping that Mac mini apart as we speak!

              @ferebee Also just found out that from Yosemite on you have /var/run/disk/** to address storage by different labels and ids oder than /dev/disk*. Not sure about the best way to address them for vdevs, since /dev/disk# easily changes. id-volume, id-media?

                @ferebee Using only half of the SSD as L2ARC would be an option as well, also help to keep the SSD healthy for a looong time. Just need to figure out a way for partitioning that ZFS can make use of a partition that OS X doesn’t want to claim.
                maclemon
                  @ferebee Sure, I don’t really worry about that at the moment. I can add/remove the L2ARC SSD at any time during runtime without issues. The worst that can happen is that I won’t use the internal SSD at all. Would be a shame, but I’ll survive. :-)

                    @ferebee It’s just that I have a 256 GB PCIe SSD in that mini that would just consume power and not be used for anything at all. So I thought I’d better make it an L2ARC than let it rot for nothing. Still need to build bonnie++ to properly speed test.

                      @ferebee El Capitan to see how that works out… just so I’ll easily find a few problems to look into in detail later. Currently I don’t know if there is any benefit from the L2ARC. I don’t have the final data/workload on those machines to test.

                        @ferebee These minis only have 16GB of which I’ll use 8GB for applications from my estimation. I’ll probably limit ZFS to 8GB ARC just to be on the safe side though the memory pressure automagic used by O3X is working really well. Currently downloading

                          @ferebee Customer “deadline” which I won’t go into detail here. That’s why I want to do as much testing as I possibly can before deploying the hardware. Testing ZFS upgrades with OS X Server (getting to unmount all drives/export pools is not easy.)
                          maclemon
                            @ferebee The deployment will be Yosemite Server in this case, no way to wait until El Capitan has settled.

                              @ferebee There is nothing else I can do with the internal SSD that makes any sense in this weird scenario. So I though to better use it as L2ARC than have is rot for no use at all. Thinking about Partitioning it to reduce wear. Don’t need 256GB L2ARC.

                                @ferebee wanted to try for science. System is running on a Samsung 850 PRO Mirror on TB with a 4×6TB HGST RAID-Z2 as storage over TB and the internal SSD of a Mac mini as L2ARC. (Should help with the latency of the many small files scattered around.)

                                  @ferebee I just have the opportunity/requirement to test a lot of things at the moment and wanted to check this as well. Not a requirement and since I can’t provide backup powered SLOG I wouldn’t run that in production anyway. It was just something I

                                    @ferebee Have you ever tried to use a single SSD as L2ARC and SLOG on OS X? If so, any pointers how you did the partitioning? gpt(8) or something else? diskutil(8) is effectively working against my intentions.

                                      @freufunk on OS X Server is Caching Server due to lack of alternatives. FreeNAS is a fine solution for SOHO.

                                        @freufunk I’m using Prosŏdy for XMPP/Jabber, nginx as webserver, samba/CIFS for file services, netatalk for AFP/TimeMachine, postfix/dovecot for email. Movies all my network services like DHCP, DNS to my pfSense firewall. Only service that I’ll keep

                                          @freufunk I’ve had my services heavily modified for a long time spending a lot of effort to work around breaking Apple’s GUI tools or Apple breaking my modifications. The complexity to do so is nowhere near the benefit of former OS X Server versions.
