 The Lion buildbot builder (tenseven-slave.macports.org) ran out of disk
 space trying to build gcc6 during this build:

 How much disk space is free? Can we get more? Or can we investigate if
 there's anything taking up space unnecessarily?

 I imagine most of the disk space will be taken up by
 /opt/local/var/macports/software, because the way we have the buildbot
 builders set up is that all ports remain installed, but deactivated. This
 means that as more and more ports get added to MacPorts over time, more
 and more disk space is needed on the builders.

 I'm not certain how the buildbot builder's disk volumes are set up... I
 thought a SAN or file share might be involved, but I'm not sure what parts
 are on that and what parts are on each builder's local disk volumes.

 Is there a system in place that monitors our servers' disk space? It's
 important that we resolve low disk space issues before we run out
 completely, as happened here.
