[Orca-users] inflated disk stats (not ignoring disksuite metadevices?)

We're running a snapshot version from 2005 (revision 490), and I've
noticed that a couple of the disk stats seem to be massively inflated:
Disk System Wide Reads/Writes Per Second
Disk System Wide Transfer Rate
Comparing the orcallator file to iostat for the same time (midnight):
Orcallator:
disk_rd/s disk_wr/s disk_rK/s disk_wK/s
0.1 8534.2 0.6 69475
iostat:

0.0 459.1 0.0 28.7 0.0 0.4 0.0 0.8 1 38 rmt/2
In this case, it looks like it's not ignoring the disksuite
metadevices. Here's what the metadevice looks like:
jeffw at alexandrite:~# metastat -p d100
d100 -m d101 1
d101 1 2 c5t600C0FF0000000000067B72FC4055300d0s0
c5t600C0FF0000000000067B74C71D24700d0s0 -i 128b
Is this something that is fixed in later releases?
Thanks!
