Hi Nathan,

The repos built for https://shaman.ceph.com/builds/ceph/wip-mempool-cacheline-49781/ a few weeks ago expired, would you be so kind as to push the latest from my repo to the ceph-ci repository[1]?

Thanks again for your help!

The reason I gave you one is because I know nothing about your environment, the topology, the system, or the load you're running.    The many commands in that script should give me enough information such that I don't come back a 2nd time asking you to rerun something because I needed more information.
