Blockmaker isn't allowed to create blocks

[ashishvk2286]

I am trying to start custom Quorum blockchain nodes. I am referring 7-nodes example for the required commands. 7-nodes example is working fine.

While starting Block Maker + Voter Node using below commands I am getting “Invalid header: block-maker-address isn't allowed to create blocks” error.
Commands:

1. Ubuntu Terminal 1:
   a. geth --datadir chain-data/blockmaker1 init genesis.json
   b. bootnode --nodekeyhex "2f64c911455fd7a835531ad223f1212908b2760de8bfc9228f1329920a0bf887" --addr="127.0.0.1:33445"
2. Ubuntu Terminal 2:
   a. GLOBAL_ARGS="--keystore /home/ashish/.ethereum/keystore --bootnodes enode://e6993a52aba890b93fcc0f7a1acae2457a6157212928fbf266ca55810d25b262115bfe36728e8d5866a64b7467083cd90f303bb16831ca6496b3e59d60cd13d5@127.0.0.1:33445 --rpc --rpcaddr 0.0.0.0 --rpcapi admin,db,eth,debug,miner,net,shh,txpool,personal,web3,quorum"
   b. geth --datadir chain-data/blockmaker1 $GLOBAL_ARGS --rpcport 22001 --port 21001 --blockmakeraccount "0xa0baf8633c30657662d2835652d954c63373bbd3" --blockmakerpassword "123" --singleblockmaker --voteaccount "0x122424aef8ce2935b1f462b43fe3916490ce6446" --votepassword "123"
   In Terminal 2 I am seeing below error.
   Error:
   E0331 11:35:10.250046 core/blockchain.go:1230] Bad block Rewrote main README #1 (0x6118be867ebb0b675fb55f32d2ad0e2d137765c43a27e502df41d505abe7ff21)

I calculated Block Maker Hex value using below command and added it in genesis.json file under Storage index: “0x0000000000000000000000000000000000000000000000000000000000000004”.
Please find attached genesis file for reference.
key = "000000000000000000000000a0baf8633c30657662d2835652d954c63373bbd3" + "0000000000000000000000000000000000000000000000000000000000000003"

web3.sha3(key, {"encoding": "hex"})
Output: "0x6b47c8152d2cea470622edd1a530f45709bb497e9ea9b28184a7b70920936878"

Please let me know if I am missing any step here.

Hi @ashishvk2286, it looks like you've used index3 (which is the index of the canVote mapping) as the <256 bit variable index> when creating the storage key for the canCreateBlocks map. But since you're setting up a block maker here, you should be using index5, which is the index of the canCreateBlocks map in the smart contract. Replacing 0...03 with 0...05 for the <256 bit variable index> should work. Let us know. We can make the docs clearer here.

Hi @tylobban, Thanks for the reply.
Yes you are right. Specifying 0...05 for the <256 bit variable index> worked. It would be really helpful if this is specified in docs. :)
