Most of the variation in disk usage is related to our Jenkins jobs. This
is to be expected, but it does mean that we will need to tend to the garden
and make sure that weeds do not take over. I have two suggestions:
1) Every Jenkins job has a description that is set up when we configure
the job. The description should (of course) explain the purpose of the job,
but it should also have some sort of tag line to identify the person who
is responsible for maintaining that job. For example, the description for
the InterpreterVM job includes this:
"This Jenkins project is maintained by Dave Lewis (lewis at mail.msen.com)"
2) All of the jobs consume a fair amount of disk space, and it is pretty
easy to let this get out of control. I think this can usually be managed
in the Jenkins project configurations, so so need to keep an eye on the
high-usage jobs an fix up their settings accordingly.
Here is the current disk utilization for our Jenkins jobs:
jenkins at box3-squeak:~/workspace$ du -s *
127408 Squeak 64-bit image
At the moment, the ReleaseSqueakTrunk job is using a lot of space, and
this is mostly due to saved images in its ./target directory. Most likely
we can purge out some of the older images to free up some space.
