Reproduced this in 2.0.6 64bit linux with the following procedure - created a collection with 6million docs with some duplicates like this:
for(var j=0;j<3;j++){
for(var i=0;i<2000000;i++){ db.people.insert(
) }
}
Then built an index on "x" with
{background:true, unique:true, dropDups:true}Then while index build is running, db.currentOp() shows output that contains odd values in "msg" for the percentage:
PRIMARY> db.currentOp()
{
"inprog" : [
{
"opid" : 6127309,
"active" : true,
"lockType" : "write",
"waitingForLock" : false,
"secs_running" : 366,
"op" : "insert",
"ns" : "test.system.indexes",
"query" : {
},
"client" : "127.0.0.1:49932",
"desc" : "conn",
"threadId" : "0x7f4a48270700",
"connectionId" : 4229,
"msg" : "bg index build 5762333/2237667 257%",
"progress" : {
"done" : 5762333,
"total" : 2237667
},
"numYields" : 1875
}
]
}
Eventually the indexing did finish building successfully.
