= phenomenon =

we have an issue with the 0.2 branch of datagrepper in production because we weren't able to test a two-server load balanced setup.

= background analysis =

OpenID uses a file-backed storage system which obviously isn't shared across both systems. putting it on the shared storage is nasty. additionally there was no testing of only one machine running the fedmsg-hub and other such things, which might be broken (don't know, can't test because we can't log in)

= implementation recommendation =

• create datagrepper02.stg.
• create a shared storage system between datagrepper01.stg and datagrepper02.stg, in much the same way as in production.
