Hi,
After a few hiccups, I managed to restore the cluster state from the
snapshot. Please confirm if they look correct. If so documentation page
needs to be updated
1. Create N nodes
2. Add some data to them
3. Create snapshot
4. Stop all nodes(cluster)
5. Delete binary_data, marsheller and sub directories of /work/db
6. Copy snapshots/snapshotname/db/binary_data to /work/db/,
7. Copy snapshots/snapshotname/db/marshaller to /work/db/
8. Copy snapshots/snapshotname/db/{nodeid} dir to /work/db/
9. Start cluster
10. Cluster should auto activate after all nodes join it
11. Cluster is ready
