| Doc Text: |
Previously, an unhandled case in the the Block Storage RBD driver prevented the deletion of snapshots if their corresponding snapshot no longer existed in the Ceph/RBD back end. This release fixes the issue, thereby allowing snapshot deletion to succeed in such cases.

Verified, RHOS8 openstack-cinder-7.0.3-2.el7ost.noarch External ceph. I had an older (openstack-cinder-7.0.3-1.el7ost.noarch) system already installed so created Cinder volume+snapshot Using rbd commands: rbd -p volumes ls -l rbd -p volumes snap unprotect vol...@... rbd -p volumes snap rm vol...@... I'd deleted the snapshot backing file on ceph. Once I attempted to delete snapshot I got the expected: [stack@undercloud-0 ~]$ cinder snapshot-list +--------------------------------------+--------------------------------------+----------------+------+------+ | ID | Volume ID | Status | Name | Size | +--------------------------------------+--------------------------------------+----------------+------+------+ | 470c312d-881d-4330-99ae-b355893e0b9b | eb02c4e1-9be5-43b1-a187-3b026d640b0c | error_deleting | - | 1 | +--------------------------------------+--------------------------------------+----------------+------+------+ Updated cinder to latest version (7.0.3-2), restarted service. When I attempted to redelete the above image it failed (cause for another bug?). [stack@undercloud-0 ~]$ cinder snapshot-delete 470c312d-881d-4330-99ae-b355893e0b9b Delete for snapshot 470c312d-881d-4330-99ae-b355893e0b9b failed: Invalid snapshot: Volume Snapshot status must be available or error. (HTTP 400) (Request-ID: req-b21ccd92-3a6e-49c5-9e19-f13a26ec27d0) ERROR: Unable to delete any of the specified snapshots. Any way to verify this bz, created a new Cinder volume+snapshot. Again deleted the snapshot backing file on Ceph. This time cinder snapshot-delete worked without errors steps below: [stack@undercloud-0 ~]$ cinder list +--------------------------------------+-----------+------------------+------+------+-------------+----------+-------------+-------------+ | ID | Status | Migration Status | Name | Size | Volume Type | Bootable | Multiattach | Attached to | +--------------------------------------+-----------+------------------+------+------+-------------+----------+-------------+-------------+ | 66af1455-4c00-4404-b0a4-f6ca0bed8e84 | available | - | vol2 | 1 | - | false | False | | | eb02c4e1-9be5-43b1-a187-3b026d640b0c | available | - | - | 1 | - | false | False | | +--------------------------------------+-----------+------------------+------+------+-------------+----------+-------------+-------------+ [stack@undercloud-0 ~]$ cinder snapshot-create 66af1455-4c00-4404-b0a4-f6ca0bed8e84 [stack@undercloud-0 ~]$ cinder snapshot-list +--------------------------------------+--------------------------------------+----------------+------+------+ | ID | Volume ID | Status | Name | Size | +--------------------------------------+--------------------------------------+----------------+------+------+ | 470c312d-881d-4330-99ae-b355893e0b9b | eb02c4e1-9be5-43b1-a187-3b026d640b0c | error_deleting | - | 1 | | 66b47c35-7fff-4ed6-90fd-9ca9af38e84c | 66af1455-4c00-4404-b0a4-f6ca0bed8e84 | available | - | 1 | +--------------------------------------+--------------------------------------+----------------+------+------+ Again back to ceph, deleted backing file of snap 66b47...

Meaning our new/second snapshot was deleted successfully while it's backing file was deleted beforehand thus another bug squashed :) Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
