I don't know what you mean by "create the partition on a small slice".
The partition table is not in any slice, it's in block zero of the disk.
Normal zone access would prevent the zone from seeing a disk or slice,
so this wouldn't be possible.
Right, I didn't say partitiion table. We simply need separate
partitions for the entire file system structure of the non-global zone.

If you create a device in the zone matching the disk you're interested
in, this might work. I haven't tried to see if you can access/modify
the disk label.
Even if this works, then the act of publishing that device to the
non-global zone broeaksthe guarantees about zone safety.

That might not be too bad, but it's not going to be done within the
non-global zone. The zone has no authority to modify SVM.
Do you mean the global SVM? Or do I have ANY control of the SVM from
any non-global zone?
|
No, none. There's only one SVM. It doesn't have enough intelligence to
handle requests from global and non-global zones differently. So access
from the non-global zones doesn't work.

Unusual...
Is waiting a week or two an option? If so, you could use ZFS and carve
up as many file systems as you wanted.

Can you provide a bit more detail about why the zone filesystems have to
be on slices? I'm hoping they could be on SVM metadevices instead.
boy, do I agree with that. But that's what he wants. Again simply

Does "he" have any good reason for this? Or is it based on iff (perhaps
old) assumptions?

No. A filesystem/slice as indicated above

I'm pretty sure that's not the way you'd normally want to run zones, but
I'm not entirely certain I understand what you're trying to accomplish.

boy, do I agree with that. But that's what he wants. Again simply
put, instead of one large partition for the non-global zone, we need an
older-style multi-physical-partition structure dedicated to the
non-global zone.
