Shell repro on master :
mongos> db.version()
3.7.1-340-gf2e1688
MongoDB Enterprise > db.runCommand({create : "cappedColl", capped : true})
{
"ok" : 1,
"$clusterTime" : {
"clusterTime" : Timestamp(1518546909, 1),
"signature" : {
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
"keyId" : NumberLong(0)
}
},
"operationTime" : Timestamp(1518546901, 2)
}
MongoDB Enterprise > db.getCollectionInfos()
[
{
"name" : "cappedColl",
"type" : "collection",
"options" : {
"capped" : true,
"size" : 0
},
"info" : {
"readOnly" : false,
"uuid" : UUID("ec90615e-a802-4529-a83f-e1e8163503a6")
},
"idIndex" : {
"v" : 2,
"key" : {
"_id" : 1
},
"name" : "_id_",
"ns" : "JavaDriverTest.cappedColl"
}
}
]
The current behavior in 3.6 (and the behavior of replica sets on master), is that creating a capped collection without a size specified is an error:
MongoDB Enterprise > db.runCommand({create : "cappedColl", capped : true})
{
"ok" : 0,
"errmsg" : "specify size:<n> when capped is true",
"code" : 14832,
"codeName" : "Location14832"
}
