bedrock init error 66 : Decompression error : ERROR_contentChecksum_invalid

[BoogalooLi]

I want to run a fullnode by docker, but the logs in bedrock-init shows snapshot checksum invalid.

This is a bug in lz4 that's installed by apt. Will try to fix it

Can I fix it manually? Thank you

You can manually stop docker compose (docker compose down), extract bedrock.tar.lz4 in the docker volume folder and then start docker again (docker compose up -d)

cd to docker volume directory as root

cd /var/lib/docker/volumes/simple-optimism-node_torrent_downloads/_data

(Path may differ if not using Ubuntu)

And extract bedrock.tar.lz4 to /var/lib/docker/volumes/simple-optimism-node_op_geth/_data (Different volume)

After extracting the data and rerun the docker containers, bedrock-init download the file again.

I assume it tries to download again because the bedrock-init checks for the existence of a /shared/initialized.txt file which is only created after the script has completed.

The check is made here while the file is created here.

Because you're extracting manually without creating the flag file, it'll try to download again on the next startup.

So maybe try to create a /shared/initialized.txt file in the volume and run again?

Yes as @0xpanoramix said create an initialized.txt file in /var/lib/docker/volumes/simple-optimism-node_shared/_data.

touch /var/lib/docker/volumes/simple-optimism-node_shared/_data/initialized.txt

[BoogalooLi]

Thanks a lot. I'll try it. Thanks.
