Traceback failure for choice [3] and 7 nodes #6

Closed netzzer closed 6 years ago

CNS metrics backend storage = 4 nodes fails. Inputting 3 nodes works correctly.

Enter your choice [1-5] : 3

For this configuration 7 nodes are recommended With a minimum of 3 required

We would require to find better allocation/computation for the question, How many nodes are available ?: X X, could be anywhere from the minimum of 3 or 4 -> the highest theoretical limit of kubernetes nodes or gluster nodes (4096 ) based of which the distribution of nodes used for applications vs nodes used for logging/metrics can be computed.
