In order to restore data using the graphSON snapshot, here are the steps to follow:
Check the snapshots folder in the graphadmin pod running in your namespace:
kubectl exec -it $(kubectl get pods -lapp=aai-graphadmin -n onap --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}' | head -1) -n onap -- ls -ltr /opt/app/aai-graphadmin/logs/data/dataSnapshots/
You should see something like below
-rw-r--r-- 1 aaiadmin aaiadmin 1353242 Nov 14 21:45 dataSnapshot.graphSON.201811142145
Choose the latest snapshot that you want to restore the database with and copy the snapshot outside of the graphadmin container for safe storage as after you do dataRestore, you will need to kill all the pods as the dataRestore drops the keyspace and creates the keyspace so resource, traversal and graphadmin cannot automatically recover
kubectl cp onap/$(kubectl get pods -lapp=aai-graphadmin -n onap --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}' | head -1):/opt/app/aai-graphadmin/logs/data/dataSnapshots/dataSnapshot.graphSON.201811142145 /tmp/dataSnapshot.graphSON.201811142145
Run the following command to connect to the cassandra cluster and do a dataRestore from an earlier graphSON format
kubectl exec -it $(kubectl get pods -lapp=aai-graphadmin -n onap --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}' | head -1) -n onap gosu aaiadmin /opt/app/aai-graphadmin/scripts/dataRestoreFromSnapshot.sh dataSnapshot.graphSON.201811142145
You should see some logs being printed and at the end it will give you info on the number of vertices in the graph when successfully restored.
