Hi, We are deploying a Openstack based private cloud, we want to replace Swift with Ceph, however, during our test, we encountered the following problems, we are wondering are they true or just due to our incorrect configuration, 1 Could Ceph support to creat containers sharing the same name by different users, for example, the folowing Swift API calls go well with the Swift backed storage, swift -A http://keystone.builder/v2.0 -U user1:user1 -k user1_pass post swift_container swift -A http://keystone.builder/v2.0 -U user2:user2 -k user2_pass post swift_container however, if using Ceph backed storage, the call fails 2 Does Ceph support .rlistings ACL permission, and blacklist specification by using something like .r:*,.r:-.thief 3 Swift recently introduced the quota support, which is needed by our application. That is, user could set quota to limit the number of objects allowed to be created under a container, and the maxium space used by a container, we are wondering if there is a similar solution for Ceph or any progress on that? And we appreciate any other comments on the differences between Ceph and Swift, i.e, something Ceph can Swift cannot, or vice versa, that will really help us to make the right choice.
