Xsan and Spotlight

If you are running Xsan and think about enabling Spotlight indexing (using mdutil -i) for an Xsan volume, please don’t. Spotlight isn’t designed to work with volumes mounted on more than one machine simultaneously.

The side-effects of enabling Spotlight indexing on Xsan volumes are:

  • Weird error messages when renaming files and folders on AFP-mounted volumes residing on Xsan volumes.
  • Inconsistent Spotlight stores; you could find files on an Xsan volume mounted on one machine which where deleted from another machine having the same Xsan volume mounted.

Setup: Mac OS X Server 10.4.9 on PPC and Intel Xserves, Xsan 1.4.x
