Test adding an organisation

[davidkel]

This should provide the capability to add Org4 to the existing 3 Org network

[davidkel]

Received the following error when the org was added and the peers joined to the channel but no chaincode installed

Code 10 is an ENDORSEMENT_POLICY_FAILURE. Here are the gateway peer logs

This seems reasonable (other runs produced more than 1 of these which is also expected). Before the adding of the org, only 2 endorsements are needed as the endorsement policy is an implicit majority. If you add another org, then you need 3 for a majority, but this txn only had 2 so fails.

retried this with setting that all 3 orgs must endorse and adding a 4th org and no errors were encountered which was to be expected.

[davidkel]

Deploying chaincode didn't affect anything but due to hyperledger/fabric-gateway#338 org4 hasn't actually started endorsing

[davidkel]

Changed the endorsement policy to force org4 to endorse and that get's picked up as expected with the usual various errors of

• ProposalResponseMismatch
• endorsement policy failure
• mvcc read conflict

As described when changing an endorsement policy
