### Split HTTP Retrieval Configuration (YAML)

Source: https://docs.old-faithful.net/running-old-faithful/installation-and-setup/configuration-files/http

This YAML configuration demonstrates how to set up split retrievals over HTTP. It references a metadata file and a mapping from piece CIDs to their respective CAR file URIs. This approach is useful when monolithic files are too large to manage directly.

```yaml
version: 1
epoch: 100
data:
  car:
    from_pieces:
      metadata:
        uri: https://files.old-faithful.net/100/metadata.yaml

### Download Snapshots and Prepare for Verification

Source: https://docs.old-faithful.net/usage/validation/epoch-208

This shell script downloads necessary pre-gap ledger and account snapshots using `aria2c` and retrieves the genesis file. It also extracts the `rocksdb.tar.bz2` archive, which contains the ledger data up to a certain slot. This prepares the environment for the verification process.

```shell
# create a working directory
export WORKING_DIR_E208=/solana/e208
mkdir $WORKING_DIR_E208
mkdir $WORKING_DIR_E208/ledger
cd $WORKING_DIR_E208

# download the pre-gap snapshots
apt install -y aria2c pv bzip2 lbzip2 zstd
aria2c -x 16 -s 16 -d $WORKING_DIR_E208/ledger https://storage.googleapis.com/mainnet-beta-ledger-us-ny5/89423444/rocksdb.tar.bz2
aria2c -x 16 -s 16 -d $WORKING_DIR_E208/ledger https://storage.googleapis.com/mainnet-beta-ledger-us-ny5/89855469/snapshot-89855469-9i59TwLmzXvbomizFZNuXgPygtx8zJ3P4nWDQuNxrTxK.tar.zst

# get genesis file
cd $WORKING_DIR_E208/ledger
wget https://api.mainnet-beta.solana.com/genesis.tar.bz2
tar -xvf genesis.tar.bz2 -C $WORKING_DIR_E208/ledger/

# extract rocksdb (will take ~10 minutes; 2 hours if using networked storage)
cd $WORKING_DIR_E208/ledger
pv rocksdb.tar.bz2 | tar -x -I lbzip2 -C ./
```

### Check System Resources for Validation

Source: https://docs.old-faithful.net/usage/validation/epoch-208

This snippet provides shell commands to verify system resources required for running the Epoch 208 validation. It checks available RAM, disk space, Ubuntu version, and GLIBC version, ensuring the environment meets the specified prerequisites.

```sh
# print used memory, should have at lest 40 GiB available
free -h

# print available disk space,m should have at least 2TiB available
df -h

# print ubuntu version; must be 22.04 LTS
lsb_release -a

# print current version; must be at least GLIBC_2.32; GLIBC 2.35 is good
ldd --version
```

### Configure Filecoin v2 Retrievals (YAML)

Source: https://docs.old-faithful.net/running-old-faithful/installation-and-setup/configuration-files/filecoin-v2-retrievals

This YAML configuration enables Filecoin v2 retrievals by specifying the version, epoch, subset CIDs, optional storage providers, and index URIs. It's a crucial step for setting up data retrieval from Filecoin archives.

```yaml
version: 1
epoch: 100
data:
  filecoin:
    enable: true
    subset_cids: 
      - bafyreibqt2nvroysxlxctgb52xxn27ectsllv2xyka4qar7ga6vupmbs3i
      - bafyreibqt212roysxlxctgb52xxn27ectsll2xsfk24qar7ga6vusdjn32
    storage_providers:
      - f02366527
indexes:
  slot_to_cid:

### Create Snapshot and Reconstruct Missing Blocks

Source: https://docs.old-faithful.net/usage/validation/epoch-208

This sequence of commands uses the patched `solana-ledger-tool` to create a snapshot before the data gap and then reconstructs the missing replayable blocks from Bigtable. It also verifies the ledger bounds and creates a new snapshot after the gap, skipping PoH verification.

```shell
# Step 0: Create a snapshot immediately before the gap
# This will take ~10 minutes
alias solana-ledger-tool="$WORKING_DIR_E208/solana-ledger-tool"
sudo sysctl -w vm.max_map_count=1400000
sudo sysctl --system
cd $WORKING_DIR_E208/ledger
solana-ledger-tool create-snapshot --ledger ./ 89856107 ./

# Step I: Recreate shreds for the missing blocks (you will need bigtable credentials)
# You need a service account key for bigtable in JSON format (to the Solana Foundation's bigtable)
# It will be used to fetch the missing blocks.
export GOOGLE_APPLICATION_CREDENTIALS=/solana/e208/bigtable.json
solana-ledger-tool bigtable reconstruct-replayable-blocks --ledger ./ --store-transaction-status --starting-slot 89856107 --ending-slot 89856602 --snapshot-archive-path=$WORKING_DIR_E208/ledger/snapshot-89856107-2Uvbz6becuTbDVLdoUXfYN81wcwR5AxVGLJFbkG5Vy2w.tar.zst

# verify bounds
# should be: slots 89423444 to 89856602
solana-ledger-tool bounds --ledger $WORKING_DIR_E208/ledger

# create a snapshot after the gap
RUST_LOG=solana=info,solana_ledger::blockstore_processor=trace solana-ledger-tool create-snapshot --skip-poh-verify --ledger $WORKING_DIR_E208/ledger 89856602 $WORKING_DIR_E208/ledger/89856602/
```

### Monolithic HTTP Retrieval Configuration (YAML)

Source: https://docs.old-faithful.net/running-old-faithful/installation-and-setup/configuration-files/http

This YAML configuration specifies the URIs for a monolithic epoch CAR file and its associated index files for HTTP retrieval. It requires the CAR file and index files to be hosted at the specified HTTP endpoints.

```yaml
version: 1
epoch: 100
data:
  car:
    uri: https://files.old-faithful.net/100/epoch-100.car
indexes:
  cid_to_offset_and_size:
    uri: https://files.old-faithful.net/100/epoch-100-bafyreibqt2nvroysxlxctgb52xxn27ectsllv2xyka4qar7ga6vupmbs3i-mainnet-cid-to-offset-and-size.index

  sig_to_cid:
    uri:  https://files.old-faithful.net/100/epoch-100-bafyreibqt2nvroysxlxctgb52xxn27ectsllv2xyka4qar7ga6vupmbs3i-mainnet-sig-to-cid.index

```

### Create Solana Snapshot with solana-ledger-tool

Source: https://docs.old-faithful.net/usage/validation/epoch-208

Creates a new snapshot from existing ledger data and a previous snapshot archive. This command reconstructs a ledger state at a specific slot, useful for synchronizing or creating new nodes. It can skip Proof-of-History verification for faster processing.

```bash
solana-ledger-tool create-snapshot \
    --skip-poh-verify \
    --ledger $WORKING_DIR_E208/ledger-after-gap \
    --snapshot-archive-path $WORKING_DIR_E208/ledger/89856602/ \
    89865552 $WORKING_DIR_E208/ledger-after-gap/89865552/
```

--------------------------------

### Configure RPC Server Proxy Settings

Source: https://docs.old-faithful.net/usage/rpc-server

This JSON configuration file defines the behavior of the RPC server's proxy mode. It specifies the target URL for proxying, custom headers to be included in proxy requests, and whether to proxy requests that initially failed to be served from archives.

```json
{
	"target": "https://api.mainnet-beta.solana.com",
	"headers": {
		"My-Header": "My-Value"
	},
	"proxyFailedRequests": true
}
```

--------------------------------

### faithful-cli: Generate All Indexes

Source: https://docs.old-faithful.net/running-old-faithful/sourcing-data/generating-from-rocksdb/creating-indexes

This command generates all required indexes for a CAR file. It requires the path to the CAR file and an output directory for the generated indexes. Ensure the CAR file is available locally. Optional flags can be used to specify a temporary directory and to verify the generated indexes.

```bash
faithful-cli index all <car-file> <output-dir>
```
