Overview * You've been solo mining against 4 partitions of packed data * You want to repack it so you can join a mining pool * You want to repack in place so you don't need any extra storage capacity * Your packed data is stored on 4TB disks and is packed using the mining address `En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI` * You want to repack your data to the mining address `Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY` * You'll use one of the DHA-provided public VDF servers * You'll use the publicly available NSFW filter provided by Shepherd * **NOTE** Unlike with the other two repacking processes ("Sync and Pack" and "Cross-Module Repack"), you will **not** need to split up the "Repacking in Place" process into two steps. Entropy generation and repacking will happen in a single step. * Run your miner with: * a `repack_modules` entry for each storage module, describing the source and target packing * After the repack in place completes you'll need to rename all your storage module directories * See [Running Your Node](/developers/mining/readme/running.md) for more information 2. Sample Directory Structure * Mount points for 4TB disks that store your packed data: * `/mnt/a` * `/mnt/b` * `/mnt/c` * `/mnt/d` * `data_dir`: `/opt/data` * Storage module symlinks: * `/opt/data/storage_modules/storage_module_0_En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI.replica.2.9` -> `/mnt/a` * `/opt/data/storage_modules/storage_module_1_En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI.replica.2.9` -> `/mnt/b` * `/opt/data/storage_modules/storage_module_2_En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI.replica.2.9` -> `/mnt/c` * `/opt/data/storage_modules/storage_module_3_En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI.replica.2.9` -> `/mnt/d` * Wallets: no wallet.json needed since you are only packing ## 3. Sample Launch Command Launch your node with the configuration file shown in the next section: ```sh ./bin/start --config_file /opt/arweave/config.yaml ``` ## 4. Sample Configuration The same configuration in YAML, JSON, and command-line form: {% tabs %} {% tab title="YAML" %} `/opt/arweave/config.yaml`: ```yaml data_dir: /opt/data peers: trusted: - peers.arweave.xyz vdf_server: - vdf-server-3.arweave.xyz randomx: large_pages: true mining: address: "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" sync: jobs: 200 transactions: blocklist: urls: - "https://public_shepherd.arweave.net" repack_modules: - partition: 0 from_format: replica_2_9 from_address: "En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI" to_format: replica_2_9 to_address: "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" - partition: 1 from_format: replica_2_9 from_address: "En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI" to_format: replica_2_9 to_address: "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" - partition: 2 from_format: replica_2_9 from_address: "En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI" to_format: replica_2_9 to_address: "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" - partition: 3 from_format: replica_2_9 from_address: "En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI" to_format: replica_2_9 to_address: "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" ``` {% endtab %} {% tab title="JSON" %} `/opt/arweave/config.json`: ```json { "data_dir": "/opt/data", "peers": { "trusted": ["peers.arweave.xyz"], "vdf_server": ["vdf-server-3.arweave.xyz"] }, "randomx": { "large_pages": true }, "mining": { "address": "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" }, "sync": { "jobs": 200 }, "transactions": { "blocklist": { "urls": ["https://public_shepherd.arweave.net"] } }, "repack_modules": [ { "partition": 0, "from_format": "replica_2_9", "from_address": "En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI", "to_format": "replica_2_9", "to_address": "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" }, { "partition": 1, "from_format": "replica_2_9", "from_address": "En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI", "to_format": "replica_2_9", "to_address": "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" }, { "partition": 2, "from_format": "replica_2_9", "from_address": "En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI", "to_format": "replica_2_9", "to_address": "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" }, { "partition": 3, "from_format": "replica_2_9", "from_address": "En2eqsVJARnTVOSh723PBXAKGmKgrGSjQ2YIGwE_ZRI", "to_format": "replica_2_9", "to_address": "Q5EfKawrRazp11HEDf_NJpxjYMV385j21nlQNjR8_pY" } ] } ``` {% endtab %} {% tab title="CLI" %} With the CLI form there is no config file - every option is passed as a flag, with list options as a single-quoted JSON value (see [Command-line Flags](/developers/mining/readme/configuration.md#3-command-line-flags) for the value syntax).
