Description Mike Hackett 2020-03-23 20:15:37 UTC

Description of problem:
As discussed in several meetings with Josh and Neha we are looking to relax the requirements for block.db size on RBD specific workloads from 4% to 1%. This will be ONLY for RBD and general Openstack workloads (cinder/glance). 

Please see BlueStore FAQ for details:
