Hi Pawel, In addition to the current SMI label requirement for booting, I believe another limitation is that the boot info must be contiguous. I think an RFE is filed to relax this requirement as well. I just can't find it right now. Thanks, Cindy On 12/18/11 04:52, Pawel Jakub Dawidek

That's why I'm asking. I think it should always mirror the partition table and allocate exactly the same amount of space so that the pool doesn't suddenly change sizes unexpectedly and require a disk size that I don't have at hand, to put the mirror back up. Gregg On 12/18/2011 4:08 PM,

Hi Gregg, Yes, fighting with partitioning is just silly. Santa will bring us bootable GPT/EFI labels in the coming year is my wish so you will be able to just attach disks to root pools. Send us some output so we can see what the trouble is. In the meantime, the links below might help.

The issue is really quite simple. The solaris install, on x86 at least, chooses to use slice-0 for the root partition. That slice is not created by a default format/fdisk, and so we have the web strewn with prtvtoc path/to/old/slice2 | fmthard -s - path/to/new/slice2 As a way to cause the
