    That’s still true, but performance has changed a lot since Jim Salter wrote that. There was a time When 2x mirrored vdevs (the equivalent to raid 10) would have been preferable to raidz2, but performance of both ZFS and disks themselves has improved enough that there wouldn’t be much of a difference in performance between these two in a home lab.

    Personally, I agree with you in that mirrors are preferable, mostly because I don’t really need high availability as much as I want an easier time restoring if a disk fails.


  • just like ssh -X

    No, that’s not what’s happening. X11 forwarding is telling the server to treat a TCP socket as a display, and after passing xauth, the frames are just shoveled into an ssh session. Waypipe is serializing Wayland messages so they can be redirected to multiple portals, specifically over a socket. They don’t really work the same at all.

    I didn’t know XFCE supported Wayland

    Some parts of xfce do, xfwm4 does not.

    so I casually ran vncserver, which launched xfce4-session

    This is because your vnc is configured to do so.

    except that it attached itself to the Wayland display (proxied to my local machine) rather than X display of TigerVNC. And here come the full XFCE right to my local machine (which is running Plasma).

    This part doesn’t make a lot of sense.

    If invoking xfce4-session works, it means you are doing so over vnc, not waypipe.










  • Be careful.

    Because it only formats stdin streams to into string(s), xargs can be very dangerous, depending on the command to which the arguments are being passed.

    Xargs used to be a practical way to get around bash globbing issues and parenthetical clause behavior, but most commands have alternate and safer ways of handling passed arguments.

    find -exec is preferable to xargs to avoid file expansion “bombs”, plus find doesn’t involve the shell, so it doesn’t care about whitespace problems.






  • Setting it up with zero experience with how it works or how ZFS works was quite intimidating for me.

    But you got through it, and ZFS isn’t a walk in the park for most. I think you’re selling yourself short.

    As someone else mentioned, leaving truenas on the asustor and using a container orchestrator or a hypervisor on the Xeon machine sounds like a good plan to me.
