Building 12.1.1 for EPEL7 would be VERY bad IMNSHO. 0.80.7 _is_ seriously
out of date, but:
1) You can't upgrade directly from 0.80.7 to 12.1.1 without upgrading to at
least 0.94.X and then 10.2.X first, and there are probably other
intermediate steps as well (you'd have to dig through the release notes to
Upgrading a Ceph installation is a non-trivial affair. Depending on the
versions involved and the amount of data in your system it can take days
for even a small installation. There are also a number of prerequisites
that need to be checked before upgrading like the underlying filesystem
used, file ownership, config settings etc.
2) I suspect that most people that are running Ceph on a CentOS/RHEL system
have switched to using the repos provided by Ceph at download.ceph.com
primary advantage of the upstream Ceph repos is that you can pin your
system to a specific release train. I personally am using Jewel currently,
but Ceph maintains repos for many different release trains.
I'm sure that I wouldn't be the only person that would be incredibly
annoyed if a "yum upgrade" upgraded Ceph to Luminous before I was ready.
For one thing, 12.1.1 is considered a release candidate by Ceph. I'm not
upgrading my Ceph cluster until at least 12.2.0 (which is going to be the
stable release) and likely will wait until 12.2.1. I'm also going to wait
until I'm good and ready. Since major operations can take days (literally),
I'm not going to do the upgrade just before I leave town for the weekend
Using the upstream Ceph repos means that I can switch from Jewel to
Luminous when I'm ready and still get upgrades for the kernel etc. without
a lot of bother.
3) Personally I think that the Ceph packages should just be deprecated from
the EPEL repo. Without the ability to provide packages for multiple release
trains theres no sane way to allow the end user to stay on a specific
release train until they are ready to upgrade, rather than when the package
manager decides to upgrade.

The last version of Ceph that was built in epel7 was 0.80.7, back in
That's pretty seriously out of date.
Is anyone going to have any heartache if I build 12.1.1 for epel7?
