Red Hat Bugzilla – Bug 1373598
OSP-9/10 upgrades fails on upgrade because of mariadb-libs package conflict.
Last modified: 2018-01-16 07:12:06 EST
Description of problem: On a OSP-9 platform using rhel 7.2, running the upgrade -y fails. 18:15:37 + yum -y -q update Total 30 MB/s | 80 MB 00:00:02 Running transaction check Running transaction test Transaction check error: file /usr/lib64/mysql/plugin/dialog.so from install of mariadb-libs-1:5.5.50-2.el7.x86_64 conflicts with file from package mariadb-galera-server-1:5.5.42-2.el7ost.x86_64 file /usr/lib64/mysql/plugin/mysql_clear_password.so from install of mariadb-libs-1:5.5.50-2.el7.x86_64 conflicts with file from package mariadb-galera-server-1:5.5.42-2.el7ost.x86_64 The package are 7.2 and the enabled repository are 7.3 as required by https://bugzilla.redhat.com/show_bug.cgi?id=1373140 [root@overcloud-controller-0 ~]# yum repolist Loaded plugins: product-id, search-disabled-repos, subscription-manager, versionlock This system is not registered to Red Hat Subscription Management.

Steps to Reproduce: 1. install mariadb* from 7.2 2. upgrade repo to 7.3 3. upgrade packages. Actual results: the above failure Expected results: successful mariadb upgrade
Some more packages information: Repository rhelosp-rhel-7-common is listed more than once in the configuration mariadb-libs.x86_64 1:5.5.50-1.el7_2 @koji-override-0/7.2 [root@overcloud-controller-0 ~]# yum list installed | grep mariadb-galera Repository rhelosp-rhel-7-common is listed more than once in the configuration mariadb-galera-common.x86_64 1:5.5.42-2.el7ost @rhos-9.0-signed mariadb-galera-server.x86_64 1:5.5.42-2.el7ost @rhos-9.0-signed
first thing I notice in mariadb-libs: * Mon May 09 2016 Honza Horak <hhorak@redhat.com> - 1:5.5.47-4 - dialog.so and mysql_clear_password.so should be in mariadb-libs package Resolves: #1138843
What I'm not understanding here is how the same -galera package works with the 7.2.z build, but not the 7.3 build. Before: mariadb-libs.x86_64 1:5.5.50-1.el7_2 mariadb-galera-server.x86_64 1:5.5.42-2.el7ost After mariadb-libs.x86_64 1:5.5.50-2.el7 mariadb-galera-server.x86_64 1:5.5.42-2.el7ost
Further updates: I ran a couple tests locally without fully installing OpenStack. With this installed: mariadb-libs.x86_64 1:5.5.50-1.el7_2 I could successfully install mariadb-galera-server. I could not update to 5.5.50-2.el7. With 5.5.50-2.el7 installed, I could not install mariadb-galera-server. This confirms that it would not impact OSP 9 today, but when RHEL 7.3 ships, we would have a problem.
As a workaround, using yum versionlock 'mariadb*' let the upgrade proceed.
The above workaround should not be used in prod env as having old mariadb* with new system library might cause unexpected error.
Verified that upgrading mariadb from 7.2.z to 7.3 did not cause described problem.
