Dynamically increasing influxdb storage on cloud

#1

Considering SSDs are very expensive to buy upfront, is there a possibility to increase the Disc space without downtime and affecting cardinality.
1)I have looked at LVM/UnionFS, but not sure of the reliability of these and other problems.
2)Having a new DB folder where we can mount a new volume on duration basis might choke the tag/series cardinality.
*currently I am trying this on AWS centos instance
