Hi all,
I installed yesterday a fresh Jenkins VM in the PHX datacenter at
jenkins.phx.ovirt.org running centos 7.2, few details:
1. It is puppetized, but still needs some verification[1], I was able to
auto-generate the plugins list from
jenkins.ovirt.org into the puppet
manifest, so it has exactly the same plugins installed. the concept might
also work for future migrations we do between the instances.
2. the jenkins data directory is 500gb configured with lvm and xfs. I was
able to do "live" storage incrase by adding a new volume to the LVM group
in the following procedure:
- created new virtio volume in the VM from phx-engine
- fdisk /dev/vdd then: n -> p -> 1 -> enter -> enter -> t -> 8e
-> w
- vgextend jenkins_lvm /dev/vdd1
- lvextend /dev/mapper/jenkins_lvm-data -L28G
- xfs_growfs /dev/mapper/jenkins_lvm-data
I was unable to increase the volume size from the engine, and then
increase the partition size(only create a new partition on the same volume
with the new increased space in the volume), not sure if that is possible.
We need to allocate it enough memory & cpu as well, if the current
hypervisors can't support it, we need to move another hypervisor into the
production DC.
3. authentication - same as
jenkins.ovirt.org for now: self enrol
and
adding permissions(ping me)
For now might be OK, but we need to think if we want to change it before
the migration, SSO will probably take time to implement so I wouldn't block
on it.
4. there is much more configuration that needs to be done to make it
functional, but i guess we can start by testing it :)

Indeed. one thing we need to make sure it to yamelize all the jobs that are
not in yaml yet, before the migration.
I also created a ticket [1], so lets continue tracking progress there.
