After reading the documentation, I was slightly confused by what the values for "bounds" should be.
http://docs.mongodb.org/manual/reference/command/moveChunk/
Can you add an example what the call should look like?
The bounds should be something like:
[ { "_id" : "minKey"}, { "_id" : "maxKey"}]
The _id is the field that is hashed (i.e., the shard key) and values are the min/max keys.
This comes from the raw chunk document:
mongos> db.chunks.findOne();
{
"_id" : "mmsdbdays.data.rrdDays-_id_\"00\"",
"lastmod" : {
"t" : 963,
"i" : 0
},
"lastmodEpoch" : ObjectId("519112d41b63763dc7582ac9"),
"ns" : "mmsdbdays.data.rrdDays",
"min" : {
"_id" : "00"
},
"max" : {
"_id" : "00b166d41e1814fefcf84424acf7e18a-153cf1c2fc605a1e4ce86238c4b4d76a-201207-btree.missRatio-indexCounters"
},
"shard" : "mmsrs5"
}
