Thanks a lot, Jens. Do I have to have cephx authentication enabled? Did you enable it? Which user from the node that contains cinder-api or glance-api are you
using to create volumes and images? The documentation at http://ceph.com/docs/master/rbd/rbd-openstack/ mentions creating new users client.volumes and client.images for cinder and glance
respectively. Did you do that? Thanks again! Narendra From: Jens-Christian Fischer [mailto:jens-christian.fischer@xxxxxxxxx]
Hi Narendra rbd for cinder and glance are according to the ceph documentation here: http://ceph.com/docs/master/rbd/rbd-openstack/ rbd for VM images configured like so: https://review.openstack.org/#/c/36042/ config sample (nova.conf): --- cut --- volume_driver=nova.volume.driver.RBDDriver rbd_pool=volumes rbd_user=volumes rbd_secret_uuid=xxxx-yyyy-zzzz libvirt_images_type=rbd # the RADOS pool in which rbd volumes are stored (string value) libvirt_images_rbd_pool=volumes # path to the ceph configuration file to use (string value) libvirt_images_rbd_ceph_conf=/etc/ceph/ceph.conf # dont inject stuff into partions, RBD backed partitions don't work that way libvirt_inject_partition = -2 --- cut --- and finally, used the following files from this repository: https://github.com/jdurgin/nova/tree/havana-ephemeral-rbd image/glance.py virt/images.py virt/libvirt/driver.py virt/libvirt/imagebackend.py virt/libvirt/utils.py good luck :) cheers jc -- On 22.11.2013, at 17:41, "Trivedi, Narendra" <Narendra.Trivedi@xxxxxxxxxx> wrote:
Hi Jean, Could you please tell me which link you followed to install RBD etc. for Havana? Thanks! Narendra From: ceph-users-bounces@xxxxxxxxxxxxxx [mailto:ceph-users-bounces@xxxxxxxxxxxxxx] On
Behalf Of Jens-Christian Fischer Hi all I'm playing with the boot from volume options in Havana and have run into problems: (Openstack Havana, Ceph Dumpling (0.67.4), rbd for glance, cinder and experimental ephemeral disk support) The following things do work: - glance images are in rbd - cinder volumes are in rbd - creating a VM from an image works - creating a VM from a snapshot works However, the booting from volume fails: Steps to reproduce: Boot from image Create snapshot from running instance Create volume from this snapshot Start a new instance with "boot from volume" and the volume just created: The boot process hangs after around 3 seconds, and the console.log of the instance shows this: [ 0.000000] Linux version 3.11.0-12-generic (buildd@allspice) (gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu7) ) #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013 (Ubuntu 3.11.0-12.19-generic 3.11.3) [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-3.11.0-12-generic root=LABEL=cloudimg-rootfs ro console=tty1 console=ttyS0 ...
