I am looking for answers to 2 major questions.
- I have used below link to setup my entire stack in production and everything looks fine so far.
The certs produced are valid for 3 years only and I don't have ca.key to create new certs, which means I will have to start from the beginning in creating certs and placing them in all hosts except I got some 50TB data and I don't want data to be lost.
Please help me out of this situation.
- While creating new certs I would also like to add new nodes to the cluster. Is it like I can just add new nodes ips and dns name and generate certs and add them the usual way or any other procedure to be followed.
Stack details: 7.10
Please help me with any possible solutions.
