Re: Errors connecting cinder-volume to ceph

["T. Nichole Williams" <tribecca@xxxxxxxxxx>]

Hi Marko,

Here’s’ my ceph config:

[ceph]
	volume_driver = cinder.volume.drivers.rbd.RBDDriver
	volume_backend_name = ceph
	rbd_pool = volumes
	rbd_ceph_conf = /etc/ceph/ceph.conf
	rbd_flatten_volume_from_snapshot = false
	rbd_max_clone_depth = 5
	rbd_store_chunk_size = 4
	rados_connect_timeout = -1
	rbd_user = cinder
	rbd_secret_uuid = c80d6505-260c-48c1-a248-7144cd5d5aab
	filter_function = "volume.size >= 2"

Setting logging to “debug” doesn’t seem to produce any new information. Here’s a snippet of /var/log/cinder/volume.log:

2017-06-19 16:54:45.056 9797 INFO cinder.volume.manager [req-e556d559-c484-4edf-a458-5afbafcb8e39 - - - - -] Initializing RPC dependent components of volume driver RBDDriver (1.2.0)

I’ve added the entirety of /etc/cinder/cinder.conf to my gist, & thank you all for any help you can provide.

Hi Nicole,

I can help, I have been working on my own openstack connected to ceph - can you send over the config in your /etc/cinder/cinder.conf file - especially the rbd relevant section starting with:

volume_driver = cinder.volume.drivers.rbd.RBDDriver

Also, make sure your rbd_secret_uuid matches the client volume secret you created.

Hello,

I’m having trouble connecting Ceph to OpenStack Cinder following the guide in docs.ceph.com & I can’t figure out what’s wrong. I’ve confirmed auth connectivity for both root & ceph users on my openstack controller node, but the RBDDriver is not initializing. I’ve dug through every related Google article I can find with no results. Any one have any tips?

Here’s output of a few sample errors, auth list from controller, & cinder-manage config list. Please let me know if you need any further info from my side.
