1，匯出快照

找一個已經同步完區塊高度的節點

lotus chain export --recent-stateroots=900 --skip-old-msgs snapshot.car

匯出時間大概30分鐘，快照3.9GB

# ls -lh | grep snapshot.car
-rw-r--r-- 1 root root 3.9G 9月  28 10:50 snapshot.car

2，匯入快照

新節點匯入快照，加速區塊高度同步

lotus daemon --import-snapshot snapshot.car

lotus sync status

# lotus sync wait
Worker: 0; Base: 98799; Target: 98799 (diff: 0)
State: complete; Current Epoch: 98799; Todo: 0

Done!
