Hi
For HyperScaleX, we have metadata nodes which are generally the first three nodes for deployment. Irrespective of how big the cluster is, only one node failure can be tolerated.
You can run the command /usr/local/hedvig/scripts/showmembers.exp to find the metadata nodes. It will show port 7010 for the nodes. Nodes that show only 7000 are not running metdata service.

yyy.prod:7010
yyy.prod:7000
zzz.prod:7010
zzz.prod:7000
The EC code will be 4+2, even if you have more than 6 nodes.

Hi
I reconfirmed and 3 nodes with have EC 4+2 and 6 nodes and above will have resiliency of 8+4 giving higher tolerance level.
