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) 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 ? -- Michael Scherer Sysadmin, Community Infrastructure and Platform, OSAS signature.asc Description: This is a digitally signed message part ___ Infra mailing list Infra@ovirt.org http://lists.ovirt.org/mailman/listinfo/infra
migration of services from linode server to phx2 lab
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. -- Eyal Edri oVirt infra team irc: eedri ___ Infra mailing list Infra@ovirt.org http://lists.ovirt.org/mailman/listinfo/infra
