This doesn't make any sense to me, since aggregates aren't owned by
the SVM.  Unless whomever set this up did something funky and I'm
about to learn something new.

From the sound of it, you're doing this from the web interface?  Can
you maybe show some of the output from the CLI commands instead?

Can you do:

    storage aggregate show -fields aggregate ,node ,is-home ,volcount
    vserver show -fields aggregate
    vol create -vserver <foo> -size 10g -aggregate <aggregate1> \
       -volume test1

And then show us the errors.

This is more at the node/disk level, not the aggregate level.

It doesn't matter what you're running, aggregates are visible to all
nodes and vservers in a cluster unless (I think!) they've been locked
down in some way.

No need... I think you really need to look at:

  storage aggregate show -instance

and see how things look there, then do:

  vserver show -instance

and see if they are locked to only allocated on a specific aggregate
somehow.  God knows why anyone does this normally...
