rbd recover tool is an offline tool to recover rbd image when ceph cluster is stopped.
It is usefull when you want to recover rbd image on a broken ceph cluster in urgent.
I have used a similar prototype tool succeessfully recovering a large rbd image in ceph cluster whose scale is 900+ osds. So I think this tool can help us to keep rbd data security.
Before you runing this tool, just make sure to stop all ceph services: ceph-mon, ceph-osd, ceph-mds.
Currently, this tool supports both raw image and snapshot, and clone image will be supported sooner.
