    Description

      I'm trying to set the usePowerOf2Sizes flag to a collection. I tried
      from a mongos:

      mongos> db.runCommand(

      {collMod : "test" , usePowerOf2Sizes : true }

      )
      {
      "raw" : {
      "rs_test/db1-test:27017,db2-test:27017" :

      { "usePowerOf2Sizes_old" : false, "usePowerOf2Sizes_new" : true, "ok" : 0, "errmsg" : "unknown option to collMod: $queryOptions" }

      },
      "ok" : 0,
      "errmsg" : "

      { rs_test/db1-test:27017,db2-test:27017: \"unknown option to collMod: $queryOptions\" }

      "
      }

      On the replicaset master, setting the flag works:

      rs_test:PRIMARY> db.runCommand(

      {collMod : "deviceInfoView" , usePowerOf2Sizes : false }

      )

      { "usePowerOf2Sizes_old" : true, "usePowerOf2Sizes_new" : false, "ok" : 1 }

      JFYI: This cluster has been upgraded from 2.4.
