Hello Nova, Cinder developers,
I would like to ask you a question concerns a Cinder patch [1]. In this patch, it mentioned that RBD features were incompatible with multi-attach, which disabled multi-attach for RBD. I would like to know which RBD features that are incompatible? In the Bug [2], yao ning also raised this question, and in his envrionment, it proved that they did not find ant problems when enable this feature. So, I also would like to know which features in ceph will make this feature unsafe?
