From my experience, the shell's performance hardly makes large difference, because the shell itself is *not* that different (that is, if there's a difference in the first place: most *nix I've ever seen ships with the same set of shells).

Given that you are stating the output printing is slow, I would like to confirm your display setting first:

1) Are you running OI inside a vm, or are you running it on real hardwares? If later, can you provide the specs of hardware in use?

2) What interface are you using, video console, terminal emulator under X, or something else (through ssh, etc)?

    a) If using video console, are you using VGA text console, or BIOS graphical console, or UEFI console? All three of them have significant performance difference on my hardware.

    b) If using X, what video driver are you using? Look into your Xorg log if you are not sure.

    c) If its something else, priovide more infomation so we can look into it.

I would at least confirm the problem really lies inside shell before asking maintainers to update it, and I would *NEVER* send out a mail with something like "OI is too slow for me so GO GET LINUX'S SHELL AT ONCE". Don't blame Google translator for it; we can tell the difference bewteen poor translation and true disrespect, and disrespectful mail calls for disrespectful replies.

From memory and not having an x86 system booted at the moment to double check: You don't need to mess around with partitioning at all. You do need to label the disk though (which is annoying). So your first format, when it asked you whether or not to label, just say yes, write the label and exit.

Assuming your rpool is currently running as a single disk (it's an x86 system and you have physically removed the old disk prior to boot), you just attach a mirror to the rpool.

Thanks for this advice.  The OpenIndiana wiki does not really address this, although it contains a lot of apparently dated information for how to install boot related software on the disk. It likely still applies for people using still using OpenIndiana 51a8 or a9.

I'm not entirely sure if writing a bootblock is required, I have always done so, but am wondering if the mirror attach already does that for you, but as someone else pointed out earlier, it doesn't hurt to re-write it.

I am strongly suspecting that this stuff was automated during the bootloader effort.
