Hi All, What are the pros and cons of running a virtual machine (with qemu-kvm) whose image is accessed via librbd or by mounting /dev/rbdX ? I've heard that the librbd method has the advantage of not being vulnerable to deadlocks due to memory allocation problems. ? Would one also benefit if using backported librbd to older kernels? E.g. 0.80 ceph with running on a 3.2.51 kernel should have bug fixes that the rbd module would not. ? Would one expect performance differences between librbd and module rbd?
Thanks! Chad. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
