This changes the main Vagrant mount point to hyperledger to provide access to all present hyperledger repositories, including fabric-samples. This will give access to new repos as they are added without requiring a modification of the Vagrantfile every time. Patch-set #1: adds fabric-samples to the list of mounted volumes if it exists Patch-set #2: fixes commit message Patch-set #3: changes strategy, mounting the parent directory to be future proof Patch-set #4: removed unrelated changes committed by error Change-Id: If126bd9d6d8806f149a0e6bacb1d8d34875f7ba4 Signed-off-by: Arnaud J Le Hors <[email protected]>

This is the first of four (1/4) sub-tasks that focus on the "green" path of consensus-type migration from Kafka to Raft. By "green" we mean that there are no failures or aborts along the way. The flow of the green path and the changes made in these 4 tasks are described below. The 4 sub-tasks are staged in a way that minimizes dependencies between them. In this sub-task we introduce changes to the orderer/common/bootstrap package (see details below). In essence, Just before the last config block of the system channel (COMMIT) is written to the ledger, the bootstrap file (a.k.a "genesis.block", do not confuse with the first block of the ledger) is swapped with the last block of the system channel. This sub-task extends package orderer/common/bootstrap to support this functionality. See respective JIRA item for further details. The "green" path for migration is the following: 1. Start with a Kafka-based ordering service 2. Send a config update tx (START-TX) on the system channel that: - Has ConsensusType.MigrationState=START - This will disable the creation of new channels - This will disable the processing of normal (standard channel) transactions 3. Wait until the START-TX is committed and get the block height H of that tx 4. Send a config update tx (CONTEXT-TX) on each of the standard channels that: - Has ConsensusType.MigrationState=CONTEXT - Has ConsensusType.MigrationContext=H - Has ConsensusType.Type="etcdraft" - Has ConsensusType.Metadata=<a marshaled etcdraft metadata: Consenters, Options, etc> 5. Send a config update tx (COMMIT-TX) on the system channel that: - Has ConsensusType.MigrationState=COMMIT - Has ConsensusType.MigrationContext=H - Has ConsensusType.Type="etcdraft" - Has ConsensusType.Metadata=<a marshaled etcdraft metadata: Consenters, Options, etc> - The metadata should be the same as for the standard channels, with the same precautions. - If committed successfully, no further configuration will be possible 6. Restart each orderer - The orderer will bootstrap into an etcdraft mode - Each channel will form a cluster - Normal transactions can resume now 7. In order to configure the channels (system or standard), make sure that the first config update tx (on any given channel) after migration has: - Has ConsensusType.MigrationState=NONE - Has ConsensusType.MigrationS=NONE - In addition to other changes to the channel's config.
