7.1, 7.1.3, 7.2
With 7.0+ comes "unsafe mode" fail over.
It is mentionned inside our documentation:
QUESTION: what do we mean EXACTLY saying following unsafe mode fail over, "failed over nodes must be re-initialized before being added back to the cluster" ?
Should the nodes be completely uninstall and re install?
I ask this question because I tested:
- doing nothing (just adding the node back) => NOT OK => the node thinks it is part of the cluster and see other nodes in orange/red state (see attachement for all detailed tests containing screen capture)
- doing a
same result => NOT OK => no change compared to previous attempts after node is re introduced.
So I think it means uninstall + re install node but would like confirmation.
Can anybody confirm?
