Dear Ceph Experts, I remember reading that at least in the past I wasn't recommended to mount Ceph storage on a Ceph cluster node. Given a recent kernel (3.8/3.9) and sufficient CPU and memory resources on the nodes, would it now be safe to * Mount RBD oder CephFS on a Ceph cluster node?
This will probably always be unsafe for kernel clients [1] [2].
* Run a VM that is based on RBD storage (libvirt?) and/or mounts CephFS on a Ceph node?
Using libvirt/qemu+librbd or ceph-fuse is fine, since they are userspace. Using a kernel client inside a VM would work too.
