Description Kenjiro Nakayama 2018-07-23 04:05:34 UTC

Description of problem:
- ceph-common package in rhel-7-server-rpms is 0.94.5. In other words, rbd --version is too old.

  [root@knakayam-ose39-crs ~]# yum info ceph-common-0.94.5-2.el7.x86_64
  Loaded plugins: product-id, search-disabled-repos, subscription-manager
  Installed Packages
  Name        : ceph-common
  Arch        : x86_64
  Epoch       : 1

  Summary     : Ceph Common

  Description : Common utilities to mount and interact with a ceph storage cluster.

  [root@knakayam-ose39-crs ~]# rbd --version
  ceph version 0.94.5 (9764da52395923e0b32908d83a9f7304401fee43)

- This causes some issues. Especially on OpenShift, all openshift nodes need to install ceph-common and runs rbd command internally. At that time, if we installed the latest Ceph(RHCS 3), the version mismatch causes error. For example, this is a report on upstream https://github.com/openshift/origin/issues/20363, but it also happened on RHEL7.

Version-Release number of selected component (if applicable): ceph-common 0.94.5 installed from rhel-7-server-rpms

How reproducible: 100%

Steps to Reproduce:
- This is a steps to prove that old ceph-common produes the error reported https://github.com/openshift/origin/issues/20363

1. Install current RHCS 3
2. Run following commands with rbd 0.94.5

  # rbd create foo --size=1 --image-format=2 -m 10.64.222.2  --key="AQBQwz5bH2KKJBAAM5tlqKLOAqft2hR+l2p+nQ==" --id=admin --pool=kube --image-feature=""

Actual results:
- Causes error "rbd: extraneous parameter --image-feature"

Expected results:
- No error.
- I confirmed that the latest rbd 12.2.4-30.el7cp does not cause any error.

Additional info:
- Please forward this ticket to proper team if RHCS/Unclassified was wrong.

RHEL 7.6 should include a newer version of ceph-common, tracked in bug 1421783 .

However, OpenShift really needs to use the packages in rhel-7-server-rhceph-3-tools-rpms, instead of rhel-7-server-rpms.

Ken, I think that rhel-7-server-rhceph-3-tools-rpms needs ceph subscription. It is difficult for openshift users to buy(?) ceph subscription for all Nodes to install only ceph-common from rhel-7-server-rhceph-3-tools-rpms. (I think that that is why RH provides ceph-common via rhel-7-server-rpms repo.)

Comment 6 Ken Dreyer (Red Hat) 2018-07-24 22:34:23 UTC

Ceph's -tools repository does not require a Ceph product subscription; only the -mon and -osd repositories do. The -tools repo is available to all RHEL customers. The idea is to make the Ceph client free to anyone with a RHEL subscription.

(If you find a particular case where a customer cannot access that repo using their RHEL SKUs, please contact our Ceph product managers to resolve that.)

Comment 7 Kenjiro Nakayama 2018-07-30 07:05:14 UTC

Thank you, Ken. I misunderstood about the subscription for the -tools repo.
