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?
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
