• To use AWS storage volume for neo4j graph database

  Step 1: Create an EBC Volume: (Type GP2) EBS volume should be in exact same region and sub region as the instance you wish to mount. Reference Link : http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-creating-volume.html Step 2: Attach EBS Volume to Instance: From volumes section - attach the volume to the instance Reference Link :http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-attaching-volume.html Step 3: Now we need to mount the drive on that instance: Panel borderColor green bgColor white titleColor green borderWidth 2 borderStyle solid title Login to your ec2 instance and list the available disks using the following command Lsblk           Check if the volume has any data using the following command.                   sudo file -s /dev/xvdf           If the above command output shows “/dev/xvdf: data”, it means your volume is empty.           Format the volume to ext4 filesystem  using the following command                 sudo mkfs -t ext4 /dev/xvdf           Create a directory of your choice to mount our new ext4 volume. I am using the name “newvolume”                 sudo mkdir /newvolume          Mount the volume to “newvolume” directory using the following command.                 sudo mount /dev/xvdf /newvolume/           cd into newvolume directory and check the disk space for confirming the volume mount.                 cd /newvolume                 df -h . Step 4:  Now we need to change the neo4j.conf file to point to new mounted space Stop neo4j Uncomment line “dbms.directories.data=data” Change to “dbms.directories.data=/newvolume/data” Step 5:  Now verify neo4j Start neo4j Create nodes and verify data Step 6: Unmount umount /dev/xvdf Step 7: Detach EBS volume Go to EC2 Volume section Select the volume Under Action select detach, if that does not works go for Force detach Step 8: Now increase the size Go to EC2 Volume section Resize the volume by modifying the volume to desired levels Step 9: Attach the volume to the new fresh instance From volumes section - attach the volume to the instance. Reference Link : http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-attaching-volume.html Step 10: Mount the volume to newly attached instance Follow step 3 above Step 11: Neo4j conf updates and data verification Follow steps 5 and 6
