OmniOS Kernel question

[manxam]

I recently installed OmniOS blood (151017) on a Dell R710 and and installed Gea's excellent Napp-it gui.

I was looking to see what the deduplication would be if enabled so ran "zdb -S mypoolname" and, after quite some time, the application crashed with OOM error (out of memory). Upon searching online I came across a post discussing 32-bit zdb application and 2GB memory limit.

After checking uname I realized that I'm running in 32 bit mode:

running on:SunOS fileserver 5.11 omnios-2e8c0ba i86pc i386 i86pc

This, afaik, was not selectable during installation. Does anyone know of a way to switch to the 64 bit kernel?
My grub menu.lst appears to only list 32 bit kernels:

title OmniOS v11 r151017
kernel /platform/i86pc/kernel/amd64/unix
module /platform/i86pc/amd64/boot_archive
title OmniOS v11 r151017 ttya
kernel /platform/i86pc/kernel/amd64/unix -B console=ttya
module /platform/i86pc/amd64/boot_archive
title OmniOS v11 r151017 ttyb
kernel /platform/i86pc/kernel/amd64/unix -B console=ttyb
module /platform/i86pc/amd64/boot_archive

Thanks,
M

SunOS fileserver 5.11 omnios-2e8c0ba i86pc i386 i86pc
does not mean 32 bit, refers only to an Intel or AMD CPU

/platform/i86pc/kernel/amd64
is 64 bit

You must not select. OmniOS is always 64 bit whenever possible.
Its only a problem the other way - 32 bit is a problem if you want.

If you want an answer for your question, you should ask at
omnios-discuss or illumos-discuss maillists where OS developers are around.

Thank you Gea. The curious part is that, though grub shows amd64, isalist shows the following [missing amd64]:
pentium_pro+mmx pentium_pro pentium+mmx pentium i486 i386 i86

I suppose I'll post on the mailing list.

Thanks!
