Description Niels de Vos 2016-01-08 16:11:12 UTC

+++ This bug was initially created as a clone of Bug #1296931 +++

Description of problem:
CentOS-7 comes with glusterfs-3.7.x in the base/updates repository. This seems to make it impossible to install glusterfs-3.6.x.

Version-Release number of selected component (if applicable):
3.6.8 (but earlier as well)

How reproducible:
100%

Steps to Reproduce:
1. Install a minimal CentOS-7 system
2. Download the packages from http://cbs.centos.org/koji/buildinfo?buildID=8205
3. Install the packages

Actual results:

Hooraay for CentOS CI!

--- Additional comment from Niels de Vos on 2016-01-08 14:27:30 CET ---

I suspect that the problem is caused by these automatically generated dependencies:

libgfapi.so.0(GFAPI_PRIVATE_3.4.0)(64bit)
libgfapi.so.0(GFAPI_3.4.0)(64bit)
libglusterfs.so.0()(64bit)
libgfxdr.so.0()(64bit)
libgfrpc.so.0()(64bit)
libgfapi.so.0()(64bit)

glusterfs-server depends on all these. The installation problem can probably be prevented when glusterfs-server only has versioned dependencies on the glusterfs-libs and glusterfs-api packages. The dependency resolver might want to install the latest version of a package that provides the requirements.

Okay, but...

I believe that many of us understand that to install 3.6.x, by definition you must first uninstall the existing 3.7.x bits that are included as part of base CentOS (and RHEL.)

Given that, is this really a bug?

Is it really possible, other than with some serious hack, to make a seamless 3.6.x install?

Can we solve this with (better) documentation?

Yes, because this happens when there are no glusterfs packages installed. The recent updates for CentOS-7 started to provide glusterfs-3.7.x (like RHEL-7.2). Before the 3.6.x versions from the Storage SIG were newer than the base/update packages from CentOS/RHEL. This has changed.

We already exclude some automatically generated provides/requirements for some parts. I think we should be able to do so for the libraries in glusterfs-libs too.

Alternatively the packages in the Storage SIG could use an epoch, so that they will always be considered newer than the CentOS/RHEL packages.

> Can we solve this with (better) documentation?

I doubt it, it will make installing more difficult.

Comment 4 Niels de Vos 2016-06-16 13:53:44 UTC

This bug is getting closed because a release has been made available that should address the reported issue. In case the problem is still not fixed with glusterfs-3.8.0, please open a new bug report.

glusterfs-3.8.0 has been announced on the Gluster mailinglists [1], packages for several distributions should become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update infrastructure for your distribution.
