I have three questions on instance storage on ec2 instance.
1. How to give different volume for workers and master, if using director client ?
2. is the above root volumne added is of EBS kind ?
3. For example, If i select worker machine of type d2.2xlarge. what is use of OOTB instance storage attached to EC2 volume since that is never mounted for root expansion ?
d2.2xlarge ===> 6 x 2048 GB (Use ?)
When defining a config, the instances section is basically a set of instance templates that you are defining.
So for your worker group, you could define a worker template, and your master group would use the master template. Given this separation, you would assign the worker template to your worker cluster group definition.
rootVolumeSizeGB: 100 # 100GB
I think that EBS root volume type is specific to the ami you choose.
Looking at the aws documentation:
It looks like d2.2xlarge doesn't say anything about EBS, so I may be assuming incorrectly but I don't think it is of the EBS kind.
