** Summary changed:
- Cinder backup of a volume is in error state with fail_reason: data must be
bytes
+ [SRU] Cinder backup of a volume is in error state with fail_reason: data must
be bytes
** Description changed:
- When creating a cinder backup of a volume when using ceph as a back end
- and the python3 version of cinder, the backup is in error state with
- fail_reason: data must be bytes.
+ [Impact]
+ When creating a cinder backup of a volume when using ceph as a back end and
the python3 version of cinder, the backup is in error state with fail_reason:
data must be bytes.
This clearly is a python3 problem. But it is unclear to me which package
is at fault. python3-cinder, ceph-common, python3-rados.
