Hello, Ceph users,
does anybody use Ceph on recently released CentOS 8? Apparently there are
no el8 packages neither at download.ceph.com, nor in the native CentOS package
tree. I am thinking about upgrading my cluster to C8 (because of other
software running on it apart from Ceph). Do el7 packages simply work?
Can they be rebuilt using rpmbuild --rebuild? Or is running Ceph on
C8 more complicated than that?
Thanks,
-Yenya

Hi Jan,
I might be wrong but I don't think download.ceph.com provides RPMs that can
be consumed using CentOS 8 at the moment.
Internally, for testing ceph@master on CentOS8, we use RPMs hosted in
chacra.
Dimitri who has worked a bit on this topic might have more inputs.
Thanks,

Hello,
What I can see here : http://download.ceph.com/rpm-octopus/el8/ is that the
first Ceph release available on CentOS 8 is Octopus and is already
accessible.
Thanks, Eric.

Hi,
I am interested in el8 Packages as well.
Is there any plan to provide el8 packages in the near future?

Ceph Octopus will be based on CentOS 8. It's due out in March.
The centos8 transition is awkward because our python 2 dependencies don't
exist on in centos8, and it is a huge amount of effort to produce them.
Octopus switches to python 3, but those dependencies cannot be produces
for centos7. So the nautilus->octopus upgrade will be either involve a
transition to the new containerized deployment (either cephadm or
ceph-ansible's container mode) or a simultaneous upgrade of the OS and
Ceph.

Hello Manuel,
if you want to get rid of all the OS type problems, you can use our free
community version to deploy Ceph.
We make sure every dependency is met and you do not need to worry about
anything like that anymore.
How to do that?
- Deploy the croit docker container on an independent management node
- Import your cluster using our assistant/wizard
- Reboot host by host with boot from network option
- Done
After that, whenever you want to migrate to a newer version or release,
there will be a button that you just click and that's all you need to do
from that point on. No hassle, no pain, no OS trouble. It all comes to with
absolutely no costs!

is there already a migration approach with minimum downtime for the non-containerized
setup when using CephFS?
The problem I see would be that after reducing to a single active MDS per rank, upgrading
that "in place" would mean machine reinstallation.
Would the following approach work?
1. Reinstall a standby MDS (upgrading to CentOS 8 and Octopus), but do not start the
actual service yet.
2. Shut down all other MDS of that rank, and start the new MDS on the freshly installed
node.
This should minimize the downtime to the "failover time" as usual.
Should that work without issues?
If so, we'll try that out sometime summer next year on a less critical cluster ;-).
Cheers,
Oliver

it took a while for the centos community to get the centos 8 buildroot
working in cbs.centos.org ... but it is usable now ... and we have got
our first Nautilus version built for C8 [1] (plus necessary deps)
we can't build centos-release-ceph-nautilus.el8 yet and there is some
work in progress still for that to happen [2] but the actual repo can
tested and consumed from [3]
the plan is to start testing these in upstream openstack CI as well, via
RDO, but any additional feedback/testing is very much welcomed
