So the size of my chaindata folder has snowballed to close to 80GB. Is there a way to reduce it or is the only way to delete it and resync geth with --syncmode fast?

Thanks!

Yes, you can do the --fast mode to reduce the chain data size. And yes, you can delete the old chaindata.

    Will that prune existing data or are you suggesting deleting and resyncing?

  • Exactly, when I try running it with --fast, I get a warning "Blockchain not empty, fast sync disabled"

  • That was my worry. My internet is super slow right now so didn't want to have to re-sync it, even with --fast mode. Oh well, I'll do it later :)
