how to create channels with new orgs in Fabric getting error Attempted to include a member which is not in the consortium

Question

Here is what I need to do in steps:

1. Create a fabric network with 2 orgs: Org1 and Org2.
2. Create a channel between them: publicchannel.
3. now add an Org3. 
4. Create a new channel: org3org1channel, between org3 and org1.

I'm experiencing problems with step 4, it is returning:

Error: got unexpected status: BAD_REQUEST -- Attempted to include a member which is not in the consortium

when I run:

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

Also, I ensure you all the paths and ENV variables are correct.

Here's my configtx.yaml file:

Organizations:
    - &OrdererOrg
        Name: OrdererOrg
        ID: OrdererMSP
        MSPDir: crypto-config/ordererOrganizations/example.com/msp

        AnchorPeers:
            - Host: peer0.org1.example.com
              Port: 7051

    - &Org2
        Name: Org2MSP
        ID: Org2MSP
        MSPDir: crypto-config/peerOrganizations/bitpay.example.com/msp

I have created new channels with the new org, using a hack:

1. I created 2 orgs as part of the consortium: org1, org2, channelcreatororg.
2. I created a new channel named org3org1channel only consisting of org1.
3. Make org3 join org3org1channel.

This works! But I think this is a hack because org1 was already in the genesis block definition of ExampleConsortium. Suppose I want to add an org4 to this network and create a channel between org4 and org3. it won't be possible. We should be able to update the consortium definition in genesis block to do so.

We should emphesise on the Profile section of the above file:

Profiles:
    ExampleOrdererGenesis:
        Capabilities:
            <<: *ChannelCapabilities
        Orderer:
            <<: *OrdererDefaults
            Organizations:
                - *OrdererOrg
            Capabilities:
                <<: *OrdererCapabilities
        Consortiums:
            ExampleConsortium:
                Organizations:
                    - *Org1
                    - *Org2
    ExampleChannel:
        Consortium: ExampleConsortium
        Application:
            <<: *ApplicationDefaults
            Organizations:
                - *Org1
                - *Org2
            Capabilities:
                <<: *ApplicationCapabilities
    TestChannel:
        Consortium: ExampleConsortium
        Application:
            <<: *ApplicationDefaults
            Organizations:
                - *Org1
                - *Org3
            Capabilities:
                <<: *ApplicationCapabilities

I think the problem is that the ExampleOrdererGenesis contains a consortium definition and it does not include Org3. Can someone help me with the steps to update it using configtxlator tool?

Did you export the channel? I know this question is silly but this is the mistake I made?

Answer 1

$: peer channel fetch config config_block.pb -o orderer.example.com:7050
    -c testchainid

   $: configtxlator proto_decode --input config_block.pb --type common.Block | jq .data.data[0].payload.data.config > config.json

   $: jq -s '.[0] * {"channel_group":{"groups":{"Consortiums":{"groups": {"TestConsortium": {"groups": {"Org3MSP":.[1]}}}}}}}' config.json ./org3.json > modified_config.json

   $: configtxlator proto_encode --input config.json --type common.Config
    --output config.pb

   $: configtxlator proto_encode --input modified_config.json --type common.Config --output modified_config.pb

  $:  configtxlator compute_update --channel_id testchainid --original config.pb --updated modified_config.pb --output org_update.pb

   $: configtxlator proto_decode --input  org_update.pb --type common.ConfigUpdate | jq . > org_update.json

  $:  echo '{"payload":{"header":{"channel_header":{"channel_id":"testchainid", "type":2}},"data":{"config_update":'$(cat org_update.json)'}}}' | jq . > org_update_in_envelope.json

   $: configtxlator proto_encode --input org_update_in_envelope.json --type common.Envelope --output org_update_in_envelope.pb

   $: peer channel signconfigtx -f org_update_in_envelope.pb

   $: peer channel update -f org_update_in_envelope.pb -c testchainid -o orderer.example.com:7050

Hey @Ayush, did the error get solved?

Yes solved it! 

I solved it using this link: https://github.com/rohitadivi/Reconfigure-BYFN/blob/master/Create_channel.md

Make sure you understand what a testchaninid is within the steps of above link. We create a channel for the orderer, when we fire our genesis block transaction using peer command. We are fetching that channel and updating it and not any other channel.
