Do I just have to make sure they have the same data-dir?

1 Answer 1


With 0.11 (and possibly, though I'm not 100% certain this was ready then), there is no particular precautions to take in order to share a database between two daemons. Pointing the daemons to the same directory using --data-dir should be safe. I'm not sure this has been tested a lot, however, so if anything like corruption should happen, please report it to https://github.com/monero-project/issues.

    It was possible in, but there were weird interactions with the txpool. In 0.11 the txpool is also stored in LMDB so those problems disappear. I've had multiple daemons running with a shared DB for a few months already, no other issues.
