koji build archiving

[Kevin Fenzi]

Koji.fedoraproject.org currently stores every rpm ever shipped to users
since the Fedora 7 days, along with a lot of information about every
build it’s ever made, even if not distributed. We have continued to grow
the storage backing koji over time, but it is close to reaching a size
we can no longer expand (75TB).

We are going to start moving builds off our main storage volume on to
slower (but still accessible) volumes in order to shrink our main volume
of active releases and make it easier to move and expand. There may be
slowdowns of builds and composes during the time we are moving builds,
but we will try and make it as transparent as possible.

All builds will continue to be available via koji.fedoraproject.org, but
you may notice a new volume name in the download path of some older
packages.

As part of initial testing of this move, we moved the *fc6* tagged
builds and this generated a number of 'buildsys.state.changed'
notifications to maintainers. We have since corrected the koji
fedora-messaging plugin to not emit these volume change events. Sorry
for the extra emails.

Please let us know if you experience excessive slowdowns or issues
related to this move.
