1. 块组成 ​

存档节点执行所有块并保留所有历史数据，包括：

  • 区块
  • 状态
  • 交易收据

2. 删除块 ​

bash
[root@eth_new snapeth]# tree -L 1 /data/coin/snapETH/geth
/data/coin/snapETH/geth
├── chaindata
    |
    ancient
├── ethash
├── jwtsecret
├── LOCK
├── nodekey
├── nodes
└── transactions.rlp
[root@eth_new snapeth]# tree -L 1 /data/coin/snapETH/geth
/data/coin/snapETH/geth
├── chaindata
    |
    ancient
├── ethash
├── jwtsecret
├── LOCK
├── nodekey
├── nodes
└── transactions.rlp

2.1 removedb ​

这种方式会 重新下载区块，但不会存储所有历史状态

geth removedb

#This is useful for deleting an old chain and sync’ing to a new one. It only affects data directories that can be re-created on synchronisation and does not touch the keystore
geth removedb

2.2 rmdb ​

#删除chaindata即可，排除ancient
rsync --delete-before -d test/ hantest/
#删除chaindata即可，排除ancient
rsync --delete-before -d test/ hantest/

3. prune ​

https://geth.ethereum.org/docs/fundamentals/pruning

  • 关闭主服务
bash
kill -15 pid
kill -15 pid
bash
geth snapshot prune-state
geth snapshot prune-state

这个方法会清理状态数据，但不会删除旧区块
