We are in process of setting up es4 and es5 as new external store sections. Once those are online, es2 and es3 will become read-only like es1.
The servers are almost ready and this is the layout:
es4:
eqiad
es1020 - master
es1021 - slave
es1022 - slave
codfw (which replicates from eqiad)
es2020 - master
es2021 - slave
es2022 - slave
es5:
eqiad
es1023 - master
es1024 - slave
es1025 - slave
codfw (which replicates from eqiad)
es2023 - master
es2024 - slave
es2025 - slave
The idea is to get the sections in place in dbctl and later, and once we are ready, do the changes in mediawiki config so they can started being used, which I think it can be done in separate steps.
I believe setting up new sections in dbctl is independent from making them usable in mediawiki, right?
This is the first time we set up a new section in dbctl, can you help us here @CDanis?
