[orbit-user] Problem with imaging outdoor grid nodes?

[Max Ott]

The Tutorial page states:

At the end of the imaging process, you will have 3 topology files
within your user directory:

   * system_topo_active_grid.rb - a topology with all the nodes that
have successfully been imaged
   * system_topo_failed_grid.rb - a topology with all the nodes that
have failed during the "imaging" process (possibly due to some disk
read/write errors)
   * system_topo_timedout_grid.rb - a topology with all the nodes
that have timed out the "imaging" process. These nodes correctly
started writing the image on their disk, but they did not finish
before the default timeout of 800 sec.
