Currently Koschei runs with only a single frontend machine, but all apps should have HA setup on 2+ systems, so another Koschei frontend (koschei-web02) should be installed. This is especially important after frontend was switched from RHEL to Fedora - we'll need to reinstall it twice a year and having second frontend eliminates user-visible downtime.
@msimacek Are you aware of any possible problems with having two frontends?
I'm not aware of any problems
Done, koschei-web02 was installed and haproxy configured to use it together with koschei-web01.
