Thanks both, it would seem that is giving some sensical answers, but
it would seem that find is assuming a block size of 512 as that's
what's being returned and I'm not convinced this is true...
I should possibly add that this is StaaS storage that is accessed via
SMB/NFS, I suspect some of this filesystem level detail might not be
passed across NFS/SMB.
