Your use of "sudo" for the rados CLI tool makes me wonder if perhaps the "nstcc0" user cannot read "/etc/ceph/ceph.conf" or "/etc/ceph/ceph.admin.keyring". If that's not the case, what version of qemu-img are you using? $ rpm -qa | grep qemu-img qemu-img-2.11.2-4.fc28.x86_64 $ qemu-img create -f raw rbd:rbd/test 1G Formatting 'rbd:rbd/test', fmt=raw size=1073741824 On Tue, Oct 30, 2018 at 11:56 AM Liu, Changcheng <changcheng.liu@xxxxxxxxx> wrote: > > Hi all, > > I follow below guide to create images with qemu-rbd: qemu-img create -f raw rbd:quick_rbd_test/own_image 5G; > > http://docs.ceph.com/docs/master/rbd/qemu-rbd/ > > However, it always shows “connect error”.
