      On the latest 2.5.x nightly, 92cf0713b74ce2f8b011e6768a66c4e99d75a8ea, failed index builds appear to be NOOPS:

      > db.foo.ensureIndex({a:'woohoo'});
      > db.getLastErrorObj()
      {
      	"connectionId" : 15,
      	"n" : 0,
      	"syncMillis" : 0,
      	"writtenTo" : null,
      	"err" : null,
      	"err" : null,
      	"ok" : 1
      }
      

      Note that the nightly above is prior to the new createIndexes command for SERVER-1627.

      On 2.4.9, failed index builds yield an error:

      > db.foo.ensureIndex({a:"ok"})
      {
      	"err" : "Unknown index plugin 'ok' in index { a: \"ok\" }",
      	"code" : 16734,
      	"n" : 0,
      	"connectionId" : 1,
      	"ok" : 1
      }
      > db.foo.ensureIndex({a:[1,2]})
      {
      	"err" : "bad index key pattern { a: [ 1.0, 2.0 ] }",
      	"code" : 10098,
      	"n" : 0,
      	"connectionId" : 1,
      	"ok" : 1
      }
      > db.foo.ensureIndex({a:{"ORLY":"YARLY"}})
      {
      	"err" : "bad index key pattern { a: { ORLY: \"YARLY\" } }",
      	"code" : 10098,
      	"n" : 0,
      	"connectionId" : 1,
      	"ok" : 1
      }
