I start the docker as followed in the guide:

export NETWORK=mainnet &&\
docker pull inputoutput/cardano-graphql:6.2.0-${NETWORK} &&\
docker pull inputoutput/cardano-graphql-hasura:6.2.0 &&\
docker pull cardanosolutions/cardano-node-ogmios:v5.1.0-${NETWORK} &&\
RESTORE_SNAPSHOT=https://update-cardano-mainnet.iohk.io/cardano-db-sync/13/db-sync-snapshot-schema-13-block-7519843-x86_64.tgz \
docker-compose up -d &&\
docker-compose logs -f

However, db-sync didn't start from a point where I passed as a RESTORE_SNAPSHOT parameter instead started at 0 to sync from genesis which takes too much time to get sync. Any recommendations? If I keep waiting to make it sync via genesis probably will last 2-3 weeks.

  • Rolling back to genesis like this can be due to 3 reasons: the node is not synced, the node and db-sync are running on different networks or wrong/missing ledger state directory.

  • What you mean by node is not Ogmios right? I mean my node and db-sync are running on same computer in different screens and it's sync. However, I did not pass any parameter while starting db-sync about the ledger path.

  • On the db-sync command line there is a --state-dir parameter. That specifies the directory where the ledger state is expected.

  • If the state directory is empty then it will roll back to genesis.

  • One common issue when using snapshots is that the ledger state part of the snapshot is restored to one place and db-sync expects it in another.

The snapshot will only be applied if cardano-node is synced past the snapshot point, since the benefit of using it would be eliminated given cardano-db-sync rolls back to genesis under these conditions. For best results, ensure the node is close to the network tip prior to upgrading.
