Hi Guys

Anyone know how to fix this issue with geth, looks like some kinda data coruption.

gerard@eth1:/var/log$ sudo geth --syncmode full --cache 4096 --datadir /var/lib/goethereum --datadir.ancient /var/lib/goethereum/geth/chaindata/ancient

Fatal: Failed to register the Ethereum service: ancient chain segments already extracted, please set --datadir.ancient to the correct path

The original problem was this:

Oct 28 12:09:55 eth1 systemd[1]: Started Go Ethereum Client.
Oct 28 12:09:55 eth1 geth[2295579]: Fatal: Failed to register the Ethereum service: gap (#13190610) in the chain between ancients and leveldb

Oct 28 12:10:01 eth1 systemd[1]: Stopped Go Ethereum Client.

But I saw on another forum where someone used removedb to delete the ancients folder.

How do I rebouild the ancient folder?

Here is the correct difrectory:

gerard@eth1:/var/log$ sudo ls -ltr /var/lib/goethereum/geth/

Couldnt really see anything in the help:
