Try dropping the indices first then running upgrade again.

Leonardo Galani

Listed all the indexes as the official doc says: https://docs.mongodb.com/v3.2/tutorial/manage-indexes/

now i only have the index that the mongo cant drop:

Indexes for objects:

[
{
	"v" : 1,
	"key" : {
		"_id" : 1
	},
	"name" : "_id_",
	"ns" : "nodebb.objects"
}
]
Indexes for search:
[
{
	"v" : 1,
	"key" : {
		"_id" : 1
	},
	"name" : "_id_",
	"ns" : "nodebb.search"
}
]
Indexes for searchpost:
[
{
	"v" : 1,
	"key" : {
		"_id" : 1
	},
	"name" : "_id_",
	"ns" : "nodebb.searchpost"
}
]
Indexes for searchtopic:
[
{
	"v" : 1,
	"key" : {
		"_id" : 1
	},
	"name" : "_id_",
	"ns" : "nodebb.searchtopic"
}
]
Indexes for sessions:
[
{
	"v" : 1,
	"key" : {
		"_id" : 1
	},
	"name" : "_id_",
	"ns" : "nodebb.sessions"
}
]
Indexes for system.indexes:
[ ]
Indexes for system.users:
[
{
	"v" : 1,
	"key" : {

Do you get the same error when you run ./nodebb upgrade again?

Leonardo Galani

yep.. the same error

5/12 12:09 [16752] - error: MongoError: exception: E11000 duplicate key error index: nodebb.objects.$_key_1_value_-1 dup key: { : "ip:recent", : "10.y.x.14c" }

You can try removing that document and try running ./nodebb upgrade

db.objects.remove({_key: "ip:recent", value: "insert ip here"});

Leonardo Galani

ok.. after deleting a few recent ips.. (like..12...) it worked out... wondering why it happend...
