openstack-manila-4.0.0-4.el7ost.noarch
openstack-manila-ui-2.7.1-2.el7ost.noarch

Most relevant to the problem:
python-cephfs-10.2.5-37.el7cp.x86_64


Steps to Reproduce:
1. Create a user using the following command (note that alice could be any other user):

ceph --name=client.manila --keyring=/etc/ceph/ceph.client.manila.keyring auth get-or-create client.alice -o alice.keyring

2. Try to allow that user to have access to the share:

manila access-allow <share_name> cephx alice 

3. Run 'manila access-list <share>' and see that the share is in 'error' state

4. Try to run 'manila access-deny <share> <access-id>'


Actual results:

Share access in error state and error trace in /var/log/manila/share.log (in the node that runs manila share service)

Expected results:

Access removed successfully

---

Additional info:

The solution for this problem was addressed 8 months ago and is included in python-cephfs-10.2.7-27.el7cp.x86_64.rpm - we should make sure RHOS11 includes the package with the bugfix, or maybe backport the fix.

This bugzilla has been removed from the release and needs to be reviewed and Triaged for another Target Release.

Comment 5 Dustin Schoenbrun 2017-08-25 19:41:24 UTC

Using puddle version 2017-08-22.2 I was able to log into the undercloud node in a deploy and verify that the python-cephfs-10.2.7-27.el7cp.x86_64.rpm package (or greater) is available.
