Hi kpkim,

You mean that the system needs an lvm/lvm2 layer to properly interpret 
the underlying filesystem?  

Possible, but the USR OSS list:
<http://www.usr.com/support/gpl/8700-OpenSourcesList-0.63_USR.xls>
doesn't list lvm as part of their implementation.  Would mdadm have 
been able to detect this?

I read USRobotics 8700 feature.

# Supports linear storage use (all drives as one logical drive) or
use multiple drives as primary and back-up storage
# Dynamic logical drive sizing - Add an additional drive, when
needed, and it will be integrated into the logical drive with no
effect on data

maybe... there is no lvm layer?
try vgscan / vgchange -ay

best regards.
