OpenStack Storage Clone Chain Based on Ceph

doi:10.3969/j.issn.1006-2475.2017.09.022

Abstract

Abstract: When OpenStack uses Ceph as the storage backend, the OpenStack cloud platform storage management is prone to error and inefficiency due to Ceph’s internal cloning mechanism. In order to solve and optimize the storage management technology deficiencies when OpenStack uses Ceph as a storage backend, through Ceph queries each object’s backend form based on Openstack, this paper recursively finds children-links of volume or snapshot, implements OpenStack storage Clone Chain function, and clone chain is visualized by Django and Angular JS. Through the display of the clone chain, we can clearly understand the relationship between the various storage objects OpenStack, so that to improve the efficiency of OpenStack storage management.

Key words: Ceph, OpenStack, storage, clone chain, Django
