步骤

1. 以 monad 用户身份 SSH 登录故障节点。
2. 确保 node.toml 中 statesync_threshold = 600

$ grep statesync_threshold /home/monad/monad-bft/config/node.toml
statesync_threshold = 600

1. 停止 monad 服务

sudo systemctl stop monad-bft monad-execution monad-rpc

1. 运行以下脚本以复制缺失的区块,然后执行到该点。您需要运行几次,因为在脚本执行期间链的最新高度会持续推进。
   1. 注意:在输出停止时,您需要手动中断进程(Ctrl - C)。
   2. 复制该脚本并命名为 manual-sync.sh
      #!/usr/bin/env bash
      set -euo pipefail
      
      # Load config first so SSH_PORT, REMOTE_HOST, CHAIN etc are set
      source .env
      
      : "${SSH_PORT:?SSH_PORT must be set}"
      : "${REMOTE_HOST:?REMOTE_HOST must be set}"
      : "${CHAIN:?CHAIN must be set}"
      
      echo "Reading files from $REMOTE_HOST"
      echo "Using ssh port: $SSH_PORT"
      
      # Copy proposed and finalized header symlinks first
      rsync -avP -e "ssh -p $SSH_PORT" \
        "monad@$REMOTE_HOST:/home/monad/monad-bft/ledger/headers/*_head" \
        /home/monad/monad-bft/ledger/headers/
      
      # Copy new headers and bodies, but don't overwrite existing ones
      rsync -avP --ignore-existing -e "ssh -p $SSH_PORT" \
        "monad@$REMOTE_HOST:/home/monad/monad-bft/ledger/" \
        /home/monad/monad-bft/ledger/
      
      # Note: the --state-sync flag is NOT present
      /usr/local/bin/monad \
        --chain "$CHAIN" \
        --db /dev/triedb \
        --block_db /home/monad/monad-bft/ledger \
        --sq_thread_cpu 1 \
        --log_level INFO
      
   3. 运行脚本
      REMOTE_HOST=node1.<provider>.com SSH_PORT=22 CHAIN=monad_mainnet bash manual-sync-step-1.sh
      
2. 一旦第一个脚本在 1 分钟内完成,运行以下脚本:
   1. 复制该脚本并命名为 manual-sync-step-2.sh
      #!/usr/bin/env bash
      set -euo pipefail
      
      # Load config first so SSH_PORT, REMOTE_HOST, CHAIN etc are set
      source .env
      
      : "${SSH_PORT:?SSH_PORT must be set}"
      : "${REMOTE_HOST:?REMOTE_HOST must be set}"
      : "${CHAIN:?CHAIN must be set}"
      
      # Copy current forkpoint
      rsync -av -e "ssh -p $SSH_PORT" \
        "monad@$REMOTE_HOST:/home/monad/monad-bft/config/forkpoint/forkpoint.rlp" \
        /home/monad/monad-bft/config/forkpoint/
      rsync -av -e "ssh -p $SSH_PORT" \
        "monad@$REMOTE_HOST:/home/monad/monad-bft/config/forkpoint/forkpoint.toml" \
        /home/monad/monad-bft/config/forkpoint/forkpoint.toml
      rsync -av -e "ssh -p $SSH_PORT" \
        "monad@$REMOTE_HOST:/home/monad/monad-bft/config/validators/validators.toml" \
        /home/monad/monad-bft/config/validators/validators.toml
      
      systemctl start monad-bft monad-execution monad-rpc
      
   2. 运行脚本
      REMOTE_HOST=node1.<provider>.com SSH_PORT=22 CHAIN=monad_mainnet bash manual-sync-step-2.sh
