When upgrading or deploying a Red Hat OpenStack Platform environment integrated with an external Ceph Storage Cluster from an earlier version (that is, Red Hat Ceph Storage 1.3), you need to enable backwards compatibility. To do so, add an environment file containing the following snippet to your upgrade/deployment:
parameter_defaults:
ExtraConfig:
ceph::conf::args:
client/rbd_default_features:
value: "1"

raising request for pm_ack+ for blocker? bug After applying the changes from the following two upstream patches: https://review.openstack.org/386972 https://review.openstack.org/283359 and adding the following to my Heat environment file: ExtraConfig: ceph::profile::params::rbd_default_features: '1' I was able to get a deploy with the following ceph.conf on my compute node (a ceph client): [root@overcloud-novacompute-0 ~]# cat /etc/ceph/ceph.conf [global] osd_pool_default_min_size = 1 auth_service_required = cephx mon_initial_members = overcloud-controller-0,overcloud-controller-1,overcloud-controller-2 fsid = 63089b2a-930d-11e6-aba5-525400330666 cluster_network = 192.168.1.26/24 auth_supported = cephx auth_cluster_required = cephx mon_host = 172.16.1.23,172.16.1.16,172.16.1.24 auth_client_required = cephx public_network = 172.16.1.18/24 [client] rbd_default_features = 1 [root@overcloud-novacompute-0 ~]# Next step is to get the change merged upstream. Alternatively, as a workaround measure, the overcloud can be deployed with an environment file like the following:
parameter_defaults:
ExtraConfig:
ceph::conf::args:
client/rbd_default_features:
value: "1"
Updating doctext as comment #3 indicates that the fix is supported. The user just needs to use the extra Heat form comment #3. In OSP10, compatibility with Ceph1.3 is only supported if the Ceph cluster is external. Marking this bug as depends on 1384079 because it prevents OSP10 from working with an external Ceph cluster. This is not a blocker for OSP10 since the user may simply use an environment file like the following:
parameter_defaults:
ExtraConfig:
ceph::conf::args:
client/rbd_default_features:
value: "1"
Marking this bug as POST so that testing may be done using the above. The proposed upstream fix linked from upstream LP bug 1633552 may be used for OSP11 (clonned this to 1388515 targetted for OSP11 for that purposed).
Should this be documented (in which case, this should be assigned and in the documentation component). If not, please add the TestOnly keyword. Yes, this should be documented. Apologies, I thought adding doctext and ticking requires_doc_text was sufficient. I have assigned it to the documentation component. Moving to 'NEW' to be triaged as resources allow. FYI on an additional verification: QE has verified that using the extra parms from comment #6 is necessary when using OSP10 with an external Red Hat Ceph Server of version 1.3. See this BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1393581 Thus, it's important that this be included in the OSP10 w/ Ceph docs. FYI: upstream documentation on using OSP10 with an extenral Ceph 1.3 server is in review at https://review.openstack.org/#/c/397825/ . This was vetted by me. Don, not sure if you merged this already. If not, please feel free to do so. |
