Comment 2 for bug 2016138

Hi Sofia,

thanks for your answer.

We are using as Cinder backup driver: 'cinder.backup.drivers.ceph.CephBackupDriver'

1) I used the openstackclient to change the backup state. `openstack volume backup set --state error <backup-id>`
It should do the same!? But no, I did not use the cinder client directly as you mentioned. The state could not be changed with the command I used.

2) Yes, I tried to solve the problem by let the cinder-backup service change the state to error. But this one checks at first if a volume for that backup still exists. I found the code line for that here [1]. It seems that cinder needs an existing volume even the scope is to change a backup state.

So the request fails because of the VolumeNotFound exception thrown here [2].

Thanks for your help.
