Since I've made stats from geth full node by calling rpc api, it is burdensome for me to stop geth a few hours.
Nowadays my local machine uses about 95% disk, so I want to migrate my /chaindata to another machine.
But after I copied original /chaindata to another machine while running original geth, running new full geth on another machine failed with error message.
Fatal: Error starting protocol stack: gap (#8952595) in the chain between ancients and leveldb
What I have to do? Should I have to stop geth and copy /chaindata?
