The slide of the restrospective of the experiment are available at : https://hedgedoc.softwareheritage.org/VOP9qh1MTqm4DjPQfFgNbQ
It was not easy to know if it's a lot of call or long running calls because it's regular sample and we don't have this granularity.

All the production nodes (`search-esnode[4-6]') are upgraded to bullseye
All the nodes are updated
- search-esnode0 updated without errors
Nov 25 2021
The upgrade by itself was made with the same command as explained previously.
The shard allocation was disabled during the process to avoid unnecessary movements of shard in the cluster
- The server was updated using the same procedure used for logstash0
- there is no error detected when puppet is running
- all the services are correctly started
- logstash0 upgrade
Nov 24 2021
production nodes are upgraded :
- stop the journal clients:
root@search1:~# systemctl stop swh-search-journal-client@indexed root@search1:~# systemctl stop swh-search-journal-client@objects
- flush the index to speedup the recovery
curl -XPOST http://search-esnode4:9200/_flush
For each node :
- disable shard allocation:
cat > /tmp/shard_allocation.json <<EOF { "persistent": { "cluster.routing.allocation.enable": "primaries" } } EOF
rebase
fix a typo in the commit message

'n' is an alias for 'codename' so everything should be ok
The staging elasticsearch is migrated to 7.15.2, everything looks good.
Disable the new embedded geoip database
It creates and regularly update a .geoip_database index
not used by swh_search, so removing it
