Info

MemSQL Helios does not support this command.

Enable high availability.

Usage

Enable high availability.

This will automatically update the 'redundancy_level' of the master aggregator
from 1 to 2, and evenly assign leaves to availability groups 1 and 2 (by
removing and re-adding them).

Run 'enable-high-availability --precheck-only' to verify if High Availability can be enabled on the cluster.
