D4Science Infrastructure

I already made part of the work to implement automatic backup. See commit bfaf045d437b40d143552820f93fcea7b6dcb1ff

Orient DB ansible script should be enhanced with the following features:

• possibility to upgrade hook only (need an orientdb restart)

Done. You can call the playbook with the additional '--tags=orientdb_hooks'

• upgrade selectively different instances

I don't know what do you mean with selectively. If you mean serially, I just changed the playbook to act on one instance at a time.

• monitor instances with munin-ganglia

They are on ganglia already. See http://monitoring.research-infrastructures.eu/ganglia/?c=D4Science%20Development%20servers&m=load_one&r=hour&s=by%20name&hc=4&mc=2 (we are going towards one cluster for all the dev servers. You can filter by the hostname to get the data of the orientdb servers only).

I also parametrized the atuomatic backup configuration file. See rev 7fafb2c2e3041c8c5803bf3b9da42864c1e16470

Can I launch it with the following command?
./run.sh orientdb.yml -i inventory/hosts.dev --tags=orientdb_hooks

• upgrade selectively different instances

Can I launch it with the following command if I want to decide where
./run.sh orientdb.yml -i inventory/hosts.dev -l orientdb01-d-d4s

Thanks you

Yes, correct.

You can always limit to a specific host (or to a specific group). It does not depend by the playbook configuration.

The right command is this:
./run.sh orientdb.yml -i inventory/hosts.dev -l orientdb01-d-d4s.d4science.org
