> Currently, there is no configurable limit imposed on the no of snapshots remaining in the system neither on the filesystem level nor on a snaphottable root directory. Too many snapshots in the system can potentially bloat up the namespace and with ordered deletion feature on , too many snapshots per snapshottable root directory will make the deletion of the oldest snapshot more expensive. This Jira aims to impose these configurable limits .
