Do I need the kernel module? I'm planning an Infrastructure for CephFS, QEmu and RGW. Will these need the kernel module or all is done in userspace? If I understood docs properly, the only case when the kernel module is needed is for use of a RBD block device directly from Linux, like a mount point. We never use this features, all of our system is based on KVM/qemu or RGW/CephFS. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
