We are currently testing ArangoDB3.0.6 for a POC. We are using 3 AWS m3.large machines. We set up a cluster of 1 coordinator and 2 DB servers.
Following are the commands used to bring up the cluster. Starting Server Agency : *DB server - 1:* sudo arangod --server.endpoint tcp://0.0.0.0:5001 --server.authentication false --agency.id 0 --agency.size 3 --agency.supervision true agency1 & *DB server - 2 :* sudo arangod --server.endpoint tcp://0.0.0.0:5002 --server.authentication false --agency.id 1 --agency.size 3 --agency.supervision true agency2 & *Co-ordinator :* sudo arangod --server.endpoint tcp://0.0.0.0:5003 --server.authentication false --agency.id 2 --agency.size 3 --agency.endpoint tcp://:5001 --agency.endpoint tcp://:5002 --agency.endpoint tcp://:5003 --agency.notify true --agency.supervision true agency3 & Then we started the arangodb service by following commands: *DB server1 :* sudo arangod --server.authentication=false --server.endpoint tcp://0.0.0.0:8529 --cluster.my-address tcp://:8529 --cluster.my-local-info db1 --cluster.my-role PRIMARY --cluster.agency-endpoint tcp://:5001 --cluster.agency-endpoint tcp://:5002 --cluster.agency-endpoint tcp://:5003 primary1 & *DB Server2 :* sudo arangod --server.authentication=false --server.endpoint tcp://0.0.0.0:8530 --cluster.my-address tcp://:8530 --cluster.my-local-info db2 --cluster.my-role PRIMARY --cluster.agency-endpoint tcp://:5001 --cluster.agency-endpoint tcp://:5002 --cluster.agency-endpoint tcp://:5003 primary2 & *Co-ordinator :* sudo arangod --server.authentication=false --server.endpoint tcp://0.0.0.0:8531 --cluster.my-address tcp://:8531 --cluster.my-local-info coord1 --cluster.my-role COORDINATOR --cluster.agency-endpoint tcp://:5001 --cluster.agency-endpoint tcp://:5002 --cluster.agency-endpoint tcp://:5003 coordinator & Using the WebUI we are able to create the collections and graphs. We uploaded around 100Million nodes and created edges. When we tried to truncate the edges we see the server going down. Not able to access the data after that. When we tried restarting the server by following the above mentioned steps we got the following info in logs: From DB server2: INFO cannot create connection to server '' at endpoint 'tcp://:5003' INFO cannot create connection to server '' at endpoint 'tcp://:5001' We dont want to lose the data in the database. So we would like to know about the following things. a) How to bring the coordinator and the DB servers back ? b) Previously we used to delete agency and coordinator folder from Co-ordinator and agency and primary* folder from DBservers to bring back the server and create the database again. Is there a way we can restore the database again ? Thanks -- You received this message because you are subscribed to the Google Groups "ArangoDB" group.
