Description Ken Dreyer (Red Hat) 2017-06-28 22:05:42 UTC

+++ This bug was initially created as a clone of Bug #1466054 +++

Description of problem:
RHEL Base ships one version of Ceph (Hammer), and the RH Ceph Storage layered product ships other versions of Ceph.

Sometimes these versions do not align. If a customer is on an older layered product version, and we add a newer version to RHEL base, this will break that customer's setup. The only workaround is to upgrade prematurely.

Version-Release number of selected component (if applicable):
RHCEPH 1.3, 2.3, 3.0

Steps to Reproduce:
1. Install RHCEPH 1.3 (eg. ceph-mon-0.94.something)
2. Enable a RHEL 7 Base repo that includes a newer ceph-common update.
One example is http://download.engineering.redhat.com/released/RHEL-7/7.4-Beta/Server/x86_64/os/ , which has has ceph-common-10.2.something
3. Run yum update

Actual results:
Yum errors

Expected results:
Yum does not error and does not attempt to replace the customer's RHCEPH 1.3 packages.

Additional info:
To handle this, we are going to bump the ceph package's epoch across all RHCEPH product versions. This will make RHCEPH's builds always override RHEL Base (and even upstream).

Comment 1 Ken Dreyer (Red Hat) 2017-06-28 22:07:14 UTC

QE team: to verify this bugfix in RHCEPH 1.3:

1. Sanity test installs and upgrades:

  Basic installs must succeed on RHEL 7.3 and 7.4
  Upgrades from RHCEPH 1.3 to RHCEPH 2 must succeed on RHEL 7.3 and 7.4

2. Examine the package's epoch with "--qf":

  rpm -q ceph-common --qf "%{epoch}:%{name}-%{version}-%{release}\n"

It should print "2:ceph-common" for the RHCEPH layered product's packages, and "1:ceph-common" for RHEL Base's packages.
