Description
- Steps to reproduce the behaviour
Download snapshot
bash fetch-snapshot.sh -d -c -p -D /opt/bsc/downloads/mainnet-geth-pbss-20260202 mainnet-geth-pbss-20260202
Unzip snapshot
bash fetch-snapshot.sh -e -D /opt/bsc/downloads/mainnet-geth-pbss-20260202 -E /opt/bsc/node mainnet-geth-pbss-20260202-pruneancient.csv
Startup command
~/geth --tries-verify-mode none --config /opt/bsc/config.toml --datadir /opt/bsc/node/server/data-seed --cache 8000 --rpc.allow-unprotected-txs --history.transactions 0
I've already tried starting it with --datadir.ancient, but the same problem persists.
-
Expected behaviour
Node starts successfully using the PBSS snapshot without errors. -
Actual behaviour
1.During extraction of the 2026-02-02 snapshot, an error appears near the end indicating a mismatch between the required decompression version and the actual files.
2.When starting the node, geth exits with: Fatal: Failed to register the Ethereum service: ancient chain segments already extracted, please set --datadir.ancient to the correct path
