562632 - Disable spotlight on build and talos slaves

Status: RESOLVED FIXED

(Release Engineering :: General, defect, P3)

Description

[Nick Thomas [:nthomas] (UTC+12)]

Bug 562617 was a pathological example of what can happen to the Spotlight data store of a build machine - waste 40G of a 75G disk. And there's the perf hit every time we pull from hg, or unpack a tests tarball, or just build. The only upside (I know of) for having spotlight is the occasional time-saving when debugging on a slave, which is completely out of whack with the overhead.

It's simply done by 
 sudo mdutil -i off /
 sudo mdutil -E /
and you can also remove a couple of startup items to ensure the index and front-end processes never start.

Hit this again while imaging the new talos rev3 minis with 10.6 refimage.

Also note that this is in the 10.5 refimage instructions, but not the 10.6.

Puppetmasters updated and restarted.

I posted to dev-tree-management in case we see some fluctuation in either build of test times.
