Move OmniOS installation to smaller drive

[Shad]

I've got an OmniOS installation on a 250GB drive at the moment. I have it running a SAN server using Napp-It. This was only supposed to be a temporary installation while I waited for a pair of 80GB drives to land so I could run it on a ZFS mirror.

Now my drives are here, it would be great if I could resize and clone onto one of the new 80GB drives rather than re-installing and setting it all up again. Is this doable? I'm a Windows guy unfortunately so if there's a relatively stress-free way of doing this and someone could give me a pointer or two, that would be great

Cheers!

you wont be able to resize the root partition while the os is running, but you should be able to resize the partition from any livecd with zfs support,
gparted is probably the easiest graphical way, here is a simple guide.

Thanks melvis. I've used gparted before, just wasn't sure if a Linux/Solaris install would get funny about suddenly being on a different size partition and/or drive.

So I'll resize to less than the size of the new drive, check it still works ok, clone to the new drive (is gparted ok for this or would I be better off with clonezilla?), and finally resize up to maximum size of the new drive - job done?

you should be able to do the cloning from gparted fine too, you will probably need to reinstall grub to the new drives mbr afterwards, the first time after cloning youll need to boot the partition manually with a command like the one below, with the bold x replaced by the values for your setup

set root=(hdx,x)
linux /boot/vmlinuz-xxxx ro root=/dev/sdxx
initrd /boot/initrdxxxx
boot

once into the os just reinstall grub to the new drive.

Just a quick update... this didn't work. Gparted didn't recognise the partition on the disk and couldn't do anything with it. I suspect there are ways to achieve what I wanted by some cmd line hackery but in the end I just did a fresh install.
