@arkadykanevsky as we have explained to you earlier swift-dispersion-populate is one of the couple swift tools that are designed for measuring overall cluster health. Populate creates containers and objects in the swift cloud which distributes them to all nodes. Reports checks their consistency on all nodes, thus obtaining percentage stability of swift cloud.

During deployment, we can not uniquely determine the readiness time of nodes to run populate since it varies from one minute to 10 minutes or even more.
Indefinitely increase the execution time limit in the script deem it inexpedient. An operator of cloud can run dispersion-populate and dispersion-report via UI.
