[Openstack] Network speed issue

That's normal. See the "...or none can be due to min_part_hours". Swift is refusing to move more data until the stuff likely currently in flight has settled. See https://swiftstack.com/blog/2012/04/09/swift-capacity-management/ --John > On Dec 16, 2014, at 9:09 AM, Amit Anand wrote: > >

Assuming your regions are pretty close to the same size, that's exactly what you'll get with 3 replicas across 2 regions. Some data will have 2 replicas in region 1 and one in region 2. Other data will have 1 in region 1 and 2 in region 2. --John > On Dec 16, 2014, at 9:39 AM, Amit Anand w
