| alexe9191 | Good day everyone :) I was wondering if there is a way to create an image from a volume without having to upload the image? It does not seem that this feature is implemented. | 06:46 |
| alexe9191 | Both cinder and glance are using ceph as a backend and are using the rbd driver. | 06:47 |

| masterpe[m] | You can create a image based on a volume. | 08:27 |
| masterpe[m] | alexe9191: You need to enable the image_upload_use_cinder_backend setting | 08:29 |
| alexe9191 | masterpe: Yes. However cinder will upload the volume | 08:45 |
| alexe9191 | Using ceph for both glance and cinder seems that a synergie can exist. | 08:45 |
| alexe9191 | A volume can be cloned from an image for instance without having to import/export the data from ceph. But it does not work the otherway around? | 08:46 |
| masterpe[m] | yes it first creates a snapshot from the volume and then a image. This can all be done without copy'ing the data. If you enable rbd_flatten_volume_from_snapshot it will flatten the snapshot first | 08:48 |
| alexe9191 | aaaah!! let me test that | 08:49 |
| alexe9191 | Would that work if you want to create an Image from a volume? If you create a volume snapshot first? | 08:53 |
| alexe9191 | My interest is creating an image from a volume not a volume from an image :) | 08:53 |

| JohnnyW | Hi, just a question about cinder backup functionality, I have a backup configured for ceph backend, everything was working fine in Rocky, but after upgrade I have a failure when I'm trying to create a volume backup. It says that pool None doesn't exist, but actually I have defined backup_ceph_pool defined to value backup. It says about backend API, | 09:28 |
| JohnnyW | so I'm wondering if something new pop up in stein(but I don't see a difference, I was comparing cinder.confs and everything looks OK to sample stein file) or there is some wrong configuration or there is a bug? My paste is here: http://paste.openstack.org/show/F29h1VFn4PxWxMITQvPV/ | 09:28 |
| JohnnyW | So from logs it looks like parameter is taken(backup_ceph_pool) correctly, but then it is trying to hit pool None...so I don't get it why it's trying to hit None. Any ideas? Thanks in advance for help, maybe you already faced such issue | 09:29 |

| JohnnyW | whoami-rajat: thanks for hint, but I already did a change in my config to backup_driver = cinder.backup.drivers.ceph.CephBackupDriver but problem is still visible | 10:39 |

| whoami-rajat | JohnnyW: I didn't get much time to look into it but basically your error trace points at while fetching the backup_device (i.e. volume) is failing because of pool being passed as None | 15:44 |
| JohnnyW | whoami-rajat can it be because normally volume is attached to iscsi storage while backup storage is a ceph? The error just before previously copied print is: http://paste.openstack.org/show/zurmIKqBRmR6bh8Kt3mj/ But strange thing is that it was working before(I mean in Rocky/Queens etc.). I know that new code is in python3 vs python2 before, so it | 16:07 |
| JohnnyW | can be somehow linked | 16:07 |
| whoami-rajat | JohnnyW: what is the volume backend? | 16:11 |
| JohnnyW | huawei dorado | 16:16 |
| JohnnyW | whoami-rajat: that is my backend config from cinder: http://paste.openstack.org/show/9nE3InvSWrIp9myvDf8g/ | 16:18 |
| whoami-rajat | JohnnyW: I see you also have a ceph volume backend, does backing up ceph volumes give the same error? | 16:25 |
| JohnnyW | give me 5 minutes, I will test it | 16:27 |
| JohnnyW | whoami-rajat: it works with volume at ceph backend. But strange, as it was working previously from dorado to ceph | 16:44 |
