title: Error while trying to join peer to channel in fabric
body: <p>I am trying to build a fabric network with two channels. One peer is able to join the channel but while trying to join  the second peer to channel getting following error:</p>
  
  <p><strong>Error: genesis block file not found open mychannel.block: no such file or directory</strong></p>
  
  <p>this is my code used for channel creation and joining peers:</p>
  
  <p>Creating channel:</p>
  
  <pre><code>docker exec -e "CORE_PEER_LOCALMSPID=Org2MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org2.example.com/msp" peer0.org2.example.com peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx
  </code></pre>
  
  <p>Joining peers:</p>
  
  <pre><code>docker exec -e "CORE_PEER_LOCALMSPID=Org2MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org2.example.com/msp" peer0.org2.example.com peer channel join -b mychannel.block
  
  docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer0.org1.example.com peer channel join -b mychannel.block
  </code></pre>
