[OpenIndiana-discuss] How to replace failed rpool mirror disk?

[Araragi Hokuto]

 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.
