Claim:
1. A method, in a cloud storage management system, for elastic data storage management in a storage cloud, the method comprising: monitoring, by an elastic file system manager in a resource provisioning component of a management layer of the cloud storage management system, remaining free space of a plurality of file systems in the storage cloud managed by the cloud storage management system; determining, by the elastic file system manager, a rate of change of remaining free space of each of the plurality of file systems; obtaining, by the elastic file system manager, priority group information, rules, and priority group specific thresholds from a profile data structure; responsive to the elastic file system manager determining that the rate of change of remaining free space of a given file system exceeds a threshold within the priority group specific thresholds, determining an amount to modify a size of the given file system based on a priority group of the given file system, based on the rules and priority group specific thresholds, and based on data specifying file system dependencies; configuring, by the elastic file system manager, a first data storage allocation to modify the size of the given file system by the determined amount; and configuring, by the elastic file system manager, a second data storage allocation to modify a size of the storage cloud to accommodate the first data storage allocation.
