The kernel code and Ceph proper are separate codebases, so if you’re running an old enough kernel KRBD may lack certain features, including compatibility with pg-upmap. I’m not sure about compatibility with RADOS / RBD namespaces.
Last I knew KRBD did not have support for RBD QoS, so if you need to throttle client ops for noisy neighbor reasons, that would favor librbd, as would having a super old kernel, like on CentOS 7. > > Hi, > > I need to create manually few VM with KVM.
