      Description

      This seems to have crept into 2.7.x. I'm not sure which version yet but it's likely related to SERVER-12750. If so the problem might also exist in 2.6.4.

      mongos> use foo
      switched to db foo
      mongos> db.bar.insert({foo: 'bar'})
      WriteResult({ "nInserted" : 1 })
      mongos> use admin
      switched to db admin
      mongos> db.runCommand({copydb: 1, fromdb: 'foo', todb: 'foo1'})
      { "ok" : 1 }
      mongos> db.runCommand({copydb: 1, fromdb: 'foo', todb: 'foo2', fromhost: 'localhost:27017'})
      {
      	"errmsg" : "exception: nextSafe(): { $err: \"the 'exhaust' query option is invalid for mongos queries: foo.bar { query: {}, $snapshot: true }\", code: 18526 }",
      	"code" : 13106,
      	"ok" : 0
      }
