Title:
rbd cannot delete residual image from ceph in some situations
Status in Glance:
Invalid
Status in glance_store:
Fix Released
Bug description:
When user through glance RESTful api upload image, the image generally
has a large size.
In fact, uploading a large enough image may be failed due to http connection
broken or other situations like that.
RBD supports a mechanism that when add operation failed, rollback operation
must be triggered (delete residual image if it was created).
Base on a condition, we have already encountered, that the incomplete image
has not been taken snapshot yet, then rollback operation do unprotect snap will
throw exception "rbd.ImageNotFound".
This exception will be disposed finally, while the code relating to remove
residual image from ceph has been skipped.
Therefore, re-uploading image will failed using the same image id due
to above reason (residual image already exists) & residual image need
to be deleted manually from ceph.
