            subsets of consenters for each channel - seperate orderers of an organization per channel
            Asked 2021-Jun-04 at 14:54

            I have to find a way to define subsets of consenters for each channel.

            The main purpose is to seperate orderers of an organization per channel.

            ANSWER

            Answered 2021-Jun-04 at 05:01

            The system channel is used by the ordering service as a template to create application channels. The nodes of the ordering service that are defined in the system channel become the default consenter set of new channels, while the administrators of the ordering service become the orderer administrators of the channel.

            so you define Orderer at Profile application channel section is useless

            but the ordering nodes can be added or removed from the channel by updating the application channel configuration

            so if you want to use seperate orderers per channel,after create application channel ,remove the consenter set of your application channel config you can reference https://hyperledger-fabric.readthedocs.io/en/release-2.2/config_update.html

            https://kctheservant.medium.com/add-an-orderer-to-a-running-raft-based-orderer-cluster-b6a432da138c

            I have use seperate orderers per channel successful at version 1.4.2,I think it is easier for version 2.3.x. because you can setup your fabric network without system channel.

            I have fixed it. The issue I was facing was because of not setting the CORE_PEER_TLS_ENABLED = true for CLI pod.

            One thing I have got learn from this whole model, whenever you see TLS issue, first to check for would be checking CORE_PEER_TLS_ENABLED variable. Make sure you have set it for all the pods or containers you are trying to interact with. The case can be false(for no TLS) or true(for using TLS) depending on your deployment. Other things to keep in mind is using the correct variables of fabric including FABRIC_CFG_PATH, CORE_PEER_LOCALMSPID, CORE_PEER_TLS_ROOTCERT_FILE, CORE_PEER_MSPCONFIGPATH and some others depending on your command.

            I see there are a lot of questions about this error, I have seen this solution Raft bad format but I doubled checked and the folders are right and the certs are in there, I also looked at Sans problem but for what I understand I don't need Sans when using Raft (I may be wrong). I think my problem its because I'm not handling the intermediate certificates correctly and I'm getting the error both creating a channel and in the Raft consensus.

            Hyperledger Fabric: How can I make an organization both peer and orderer nodes?
            Asked 2020-Aug-21 at 23:47

            I am building a Hyperledger Fabric network, and I am trying to make an organization have both a peer node and an ordering node. I am using cryptogen to generate the certs and keys, and am only creating one organization as a "peer organization". I had one network that had 6 organizations--5 of which had a single peer and one orderer organization with a single orderer. Then I took these configuration files and removed the orderer organization and added an orderer endpoint to one of the peer organizations. I am now getting an error.

            printed to the screen:

            Error: failed to create deliver client for orderer: orderer client failed to connect to localhost:7050: failed to create new connection: context deadline exceeded

            The problem with TLS was solved by creating two peers under the organization orgname, and designating one for the orderer. I don't understand exactly why I couldn't use the same certificates for both the peer and orderer node, but it is working now.

            The second issue I had in my update was solved by making the endorsement policies more permissive. For each organization in my configtx.yaml file, I set Readers, Writers, and Endorsements to require any member signature.

            This is what is happening:

            You created a system channel (which is the orderer genesis block) by creating the MAIN consortium. Now the system channel was created with the peer organization MSPs at that moment. Followed by this, after the network was up, you went into org1/users and created an admin identity. You update local MSP of peer but the already existing system channel was never updated.

            Possible solutions:

            1. Update the admin credentials within org1/users before the network is set up.
            2. Update the system channel configuration with the admin2 credentials post deployment by creating a channel update transaction.
            3. Enable NodeOUs so that any admin identity generated dynamically post the network deployment can perform admin related transactions.

            How to add a new Orderer Organization to existing Hyperledger Fabric network
            Asked 2020-Apr-11 at 07:52

            I am trying to add a new Orderer Organization to RAFT based existing ordering service. I am using the first-network from fabric-samples as the base network. While generating crypto-material, I have modified to generate crypto-material for 1 more orderer organization. The crypto-config.yaml looks like:

            ...

            ANSWER

            Answered 2020-Apr-11 at 07:52

            I was able to extend the first-network by adding a new Orderer Organization as follows:

            1. Start the first-network through the byfn.sh script in the fabric-samples repo in the etcdraft mode.
            2. I generated crypto-material like described in the crypto-config.yaml in the question above.
            3. Use the configtxgen tool to print the new orderer organization's MSP into JSON format.
            4. Mount or docker cp this JSON file to the running cli container.
            5. Set the environment inside the cli container corresponding to existing ordering node. Import the latest system-channel configuration. Decode it to JSON format.
            6. Edit the system channel configuration block's Orderer section to add the new orderer organization's MSP as follows:

              jq -s '.[0] * {"channel_group":{"groups":{"Orderer":{"groups": {"Orderer1Org":.[1]}}}}}' config.json orderer1org.json > config1.json

            7. Edit the system channel configuration block's Consortiums section to add the new orderer organization's MSP as follows:

              jq -s '.[0] * {"channel_group":{"groups":{"Consortiums":{"groups":{"SampleConsortium":{"groups": {"Orderer1MSP":.[1]}}}}}}}' config1.json orderer1org.json > config2.json

            8. Edit the system channel configuration block's Consenters section to add the TLS credentials for the new orderer organization's orderer.example1.com node as follows:

              cert=`base64 ../crypto/ordererOrganizations/example1.com/orderers/orderer.example1.com/tls/server.crt | sed ':a;N;$!ba;s/\n//g'`

              cat config2.json | jq '.channel_group.groups.Orderer.values.ConsensusType.value.metadata.consenters += [{"client_tls_cert": "'$cert'", "host": "orderer.example1.com", "port": 7050, "server_tls_cert": "'$cert'"}] ' > modified_config.json

            9. Encode the block, find delta, create channel update transaction, encode it as protobuf envelope and submit the channel update transaction.

            10. Fetch the latest system channel configuration block.
            11. Start one of the orderers (the one who was added to consenters list previously) using this latest fetched system channel configuration block as it's genesis.block file.
            12. Perform docker exec into the cli container. Using the environment of an existing orderer node, fetch the latest system channel configuration.
            13. Edit the system channel configuration block to add the new orderer's endpoint in the OrdererAddresses section as follows:

              cat config.json | jq '.channel_group.values.OrdererAddresses.value.addresses += ["orderer.example1.com:7050"] ' > modified_config.json

            14. Encode the block, find delta, create channel update transaction, encode it as protobuf envelope and get the block signed by Orderer1Org admin to satify the mod_policy for /Channel/OrdererAddresses resource which is set to Admins policy. This implicit meta policy expects the signature of MAJORITY Admins at that level of update. So, as the number of orderer organizations are 2 now, we need both the organization's admins to sign this system channel update transaction. Set the environment corresponding to Orderer1Org admin and run the following command:

              peer channel signconfigtx -f ordorg_update_in_envelope.pb

            15. Set the environment back to OrdererOrg admin and submit the channel update transaction. The peer channel update will automatically sign the transaction on behalf of OrdererOrg admin.

              peer channel update -f ordorg_update_in_envelope.pb -c $CHANNEL_NAME -o orderer.example.com:7050 --tls true --cafile $ORDERER_CA

            For updating any application channel, just replace the step 7 by updating the application channel configuration block's Application section to add the new orderer organization's MSP there.

            Hope this helps!
