We actually had lengthy discussions with our SAs and convinced them that we
need different mountpoints on different disks. We have our SA's guarantee
that no physical disk is used by the two mountpoints...
Will try to get a "sar -d" output from them..

Note that I enclosed the 'disk' above within quotes. Different filesystems
and mount points does not necessarily mean much in these days where a
single
storage array may be shared among multiple servers. As long as you are not
using JBODs, i.e. you are on a SAN/NAS, there is no physical guarantee that
the disks are where they purport to be. Can your SA verify that these
'disks' are actually different? A 'sar -d' during that period may reveal
some interesting results.
