When you say you got an iscsi array, is this a san, and wouldn't it have
it's own volume management? What your options are, how it is built and what
it's underlying OS might be might help a little in giving advice. Some sans
you don't really want to know what the underlying fs is, I know one big san
company came to AK for a VMUG meeting and in talking to their engineer they
have modified the fs with custom code to suit their purposes... i.e. you
fiddle with it on the back end and lose your support on the front end.
