[Lustre-discuss] split OSTs from single OSS in 2 networks

[Haisong Cai]

It does look exactly what I need. Thanks Aurllien.

From bugzilla, the patch has been checked in to 1.8.  Could someone please
point me to the source location? Is it in 1.8.5 - don't believe so,
but I thought I would check. If not, would it be in later release of 1.8?

thanks all,
Haisong
