A proper way of syncing on Erigon full node
Hi, I'd appreciate if you help me to figure out proper steps to set up Blockbook with Erigon.
My node is running in full mode (--prune.mode=full), there are all my custom parameters for docker:
- --prune.mode=full
- --torrent.port=42069
- --torrent.download.rate=100mb
- --torrent.conns.perfile=16
- --torrent.download.slots=64
- --maxpeers=100
- --nat=extip:x.x.x.x
- --http
- --http.addr=0.0.0.0
- --http.port=28545
- --http.api=eth,erigon,engine,net,web3,debug,trace,txpool
- --http.vhosts=localhost,erigon,192.168.0.12,10.0.0.12
- --ws
- --ws.port=28546
- --datadir=/data
- --authrpc.addr=0.0.0.0
- --authrpc.port=28551
- --authrpc.jwtsecret=/secrets/jwt.hex
- --authrpc.vhosts=localhost,erigon,*
- --authrpc.timeouts.read=60s
- --authrpc.timeouts.idle=5m
- --private.api.addr=0.0.0.0:9090
- --port=31303
- --beacon.api=beacon,config,debug,node,lighthouse
- --beacon.api.addr=0.0.0.0
- --beacon.api.port=5555
- --maxpeers=80
- --caplin.discovery.port=12000
- --caplin.discovery.tcpport=13000
I've also started blockbook v0.5.0 as:
blockbook
-blockchaincfg=/configs/ethereum-classic.json
-datadir=/data
-sync
-internal=0.0.0.0:9030
-public=0.0.0.0:9130
-explorer=1
-logtostderr
-workers=1
-enablesubnewtx
-extendedindex
-debug=1
And my ethereum-classic.json:
{
"address_aliases": true,
"consensusNodeVersion": "http://erigon:5555/eth/v1/node/version",

}
And don't quite get what's going on after: both processes are running fine, Blockbok syncs 46146 blocks within a minute and then kind of hangs:
% curl -sS http://10.0.0.12:38332/api/v2/ | jq .

}
And nothing happens then, for the last 30 hours in logs I see:

E0824 16:43:03.543083 1 blockbook.go:524] syncIndexLoop Block not found, will retry...
As I understood, blockbook in my configuration tries to sync from genesis.
But my fully synced node isn't archived, so it doesn't contain all blocks. I've read docs, looked at opened and closed issues I didn't get how to properly run Blockbook with my node congifuration.
Am I supposed to pass -blockheight=X and start syncing from the earliest available block on my node, or just wait?
Thanks a lot.
We experienced a similar behaviour. I believe this might be due to the bulk import reaching for the 23 million blocks, try declaring intervals in your blockbook configuration:
