Cannot sync up with blockchain #6748

Closed Mladia closed 3 years ago

Mladia commented 3 years ago

From quite some time I was not able to sync up using monerod. I think this is the problem, is there a way of fixing it, besides starting the whole sync from scratch.

I am running /usr/bin/monerod --data-dir /run/media/Data/.monero --check-updates disabled --max-concurrency 2 --log-level "1,*msg*:INFO,*net*:DEBUG" on Arch with the latest version from the Arch repos v0.16.0.1-release.

Looks like a corrupted chain. Resync is the only safe way to fix. Theoretically it's possible that popping enough blocks would fix, but it's (1) not certain as it depends on the corruption details and (2) we don't know how far to pop as we don't know all the corrupted data.

All right. Thanks.
