Hi,
We're finally able to start migrating services from linode01 to a production VMs on
the phx lab. [1]
I'd like to go over all the services and decide which ones we want to migrate and what
else exists on linode:
Dns entries: resources.ovirt.org, lists.ovirt.org
Services:
mailman
ovirt irc bot
spamassin
postfix ( aliases for ovirt.org )
package repositories
mirrorlist
Storage:
gerrit backups (still there?)
download for rpm and code (repos)
For each we should decide if we're migrating or just installing a new server with new
configuration
on phx. optimally we'd like to do it with relevant puppet classes per service.
Please share your thoughts about each service and feel free to volunteer and help our with
migrating
one of these.
[1] hopefully we'll also have the ilos working by next week, so another reason to
migrate.

Hi,
Between myself (original linode01.ovirt.org admin) and Michael (misc,
aka knower-of-stuff), what can we do to get us off this Linode
instance? From what I can tell, at least Mailman is running from there.
If we still need service failover, can we switch to another Red
Hat-provided service such as an OpenShift or OpenStack instance?
Regards,

Hi,
Between myself (original linode01.ovirt.org admin) and Michael (misc,
aka knower-of-stuff), what can we do to get us off this Linode
instance? From what I can tell, at least Mailman is running from there.

Hi Karsten,
I know this has been taking for too long, but unfortunately there are many reasons
and obstacles that prevented us from moving, which i'll explain below,
while there is a risk right now of moving services to PHX, but i think we can try.
Blocking items:
- were missing more hypervisors to the production DC ( we finally got them installed last
week, and are now in final stages of bringing them up)
- storage issue - currently NFS storage is quite slow, we are testing moving to a mixed
mode of local + nfs for the jenkins slaves,
though might be that the production service won't get affected too
much - worth a try.
- lack of monitoring for servers, which might add risk if we hit an issue.
there are some other issues, but not blocking imo.
Here is what needs to be done (per service to migrate off linode), and we'd appreciate
any help given.
1. create new VM on production DC in PHX (assign dns/ip/etc.. )
2. create puppet manifests to manage that vm, so it will be easy to reproduce it and
maintain it
3. install the relevant software on it (for e.g mailman/ircbot/etc...)
4. test to see it works
5. do the actual migration (downtime of existing service, and bringing up the new one)
(might have left out some of the steps, but thats in general)
if you or Michael can take ownership on migrating one of the services off linode, with
help from
us, it will surely hasten the process.
Eyal.
Regards,
- - Karsten

So, last time I did look, the puppet setup was a bit "unfinished" rather
overkill ( using r10k to deploy count as overkill when you do not have
stage/prod/qa, at least for me ). Did stuff changed, or should first
some effort be made to fix/automate/improve the puppet setup ?
Still using only one branch, but hiera is enabled and ready to start getting
used. It still needs some refactor but if we don't use it we will never do
it... so better using it imo
