Yury, the error seems OK. You can't download the incremental backup that was taken for the RAW disk while there was a snapshot for it and it was removed. If the snapshot removed, the backup removed also since the disk format is back to RAW now. So the error looks fine, is the bug refers to the problem with removing the ticket?
Hello, Eyal. > You can't download the incremental backup that was taken for the RAW disk while there was a snapshot for it and it was removed. > If the snapshot removed, the backup removed also since the disk format is back to RAW now. I expect more user friendly exception, like incremental backup doesn't supported, or start full backup in this case. > So the error looks fine, is the bug refers to the problem with removing the ticket? It's second problem.
This bug will refer to the first problem of failing to download the missing backup without proper error. I've open bug 1954427 to track the missing ticket issue.
Yury, can you please clarify the steps to reproduce this bug? First, is the backup done when the VM is running? Second, when the snapshot removed? after the backup started but before starting to transfer the backup disk? Please include the VDSM and the engine log that contains the snapshots and backup operations.
Hello, Eyal. > First, is the backup done when the VM is running? Yes > Second, when the snapshot removed? after the backup started but before starting to transfer the backup disk? Between two incremental backups. I deleted the snapshot and only after that started new backup > Please include the VDSM and the engine log that contains the snapshots and backup operations. In attached logs those operations should be exist

The disk is now back in RAW format and doesn't contain the previous bitmaps and checkpoints. And if the backup failed, then trying to download a non-existing backup should fail also. So can you please elaborate, did the incremental backup succeeded after the snapshot removal in your case?
Hello, Eyal. > So can you please elaborate, did the incremental backup succeeded after the snapshot removal in your case? We've done full backup and it was failed.

Yury, please provide full steps to reproduce this bug.
As this is a VEEAM/customer bug raising priority to high to get QE attention as well.
Hello Eyal. >Yury, please provide full steps to reproduce this bug. It doesn't confirm on 4.4.6
Thanks Yury, closing.
Hello Eyal, Suddenly, it confirmed on 4.4.6 I have the vm with raw and qcow. And i couldn't start backup for the raw disk it always failed Caused by: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed to StartNbdServerVDS, error = Unsupported operation: 'reason=Cannot export bitmap from RAW volume, context={}', code = 2009

Hello, Nir and Eyal. I couldn't confirm this bug again. It's some floating defect and i can't find proper way to confirm. But after several manipulation in that vm with snapshots i got the new case.

It failed with the same error. 2021-07-21 17:30:32,652+02 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.HSMGetAllTasksStatusesVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-76) [] Failed in 'HSMGetAllTasksStatusesVDS' method 2021-07-21 17:30:32,652+02 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.HSMGetAllTasksStatusesVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-76) [] Unexpected return value: TaskStatus [code=2009, message=value=Unsupported operation: "reason=Cannot add bitmaps from parent volume with raw format, context={'srcVolUUID': 'fcd40610-ed08-47ad-b542-a7df1a9174dd'}" abortedcode=2009] -- Result: 'cleanSuccess' -- Message: 'VDSGenericException: VDSErrorException: Failed to HSMGetAllTasksStatusesVDS, error = value=Unsupported operation: "reason=Cannot add bitmaps from parent volume with raw format, context={'srcVolUUID': 'fcd40610-ed08-47ad-b542-a7df1a9174dd'}" abortedcode=2009, code = 2009', -- Exception: 'VDSGenericException: VDSErrorException: Failed to HSMGetAllTasksStatusesVDS, error = value=Unsupported operation: "reason=Cannot add bitmaps from parent volume with raw format, context={'srcVolUUID': 'fcd40610-ed08-47ad-b542-a7df1a9174dd'}" abortedcode=2009, code = 2009' I'm trying to simplify the case for the new bug.

Steps to Reproduce from duplicate bug 1990854: 1. Create vm with qcow and raw disk and powered on it 2. Do full backup 3. Do incremental backup 4. Powered off VM 5. Do incremental backup
(In reply to Eyal Shenitzky from comment #21) > Steps to Reproduce from duplicate bug 1990854: > 1. Create vm with qcow and raw disk and powered on it > 2. Do full backup > 3. Do incremental backup > 4. Powered off VM > 5. Do incremental backup easier steps to reproduce: 1. Create a VM with RAW and QCOW disk (can be done by creating the disks via the UI on NFS domain and setting 'Incremental backup enabled' for one disk and not for the other). 2. Create a full backup for the VM that includes all the VM's disks 3. Finalize the VM backup 4. Start an incremental backup that includes all the VM's disks and use the created checkpoint from step 2. 5. Download the RAW disk. Downloading the RAW disk will fail with the mentioned error. Expected results - Downloading the RAW disk in mixed backup should work without any issues.
Version: vdsm-4.40.90.1-1.el8ev.x86_64 ovirt-engine-4.4.9-0.6.el8ev.noarch Verification conclusions: The expected output matched the actual output. The total flow mentioned was done with no errors, I was able to download the RAW disk in mixed backup at the end of the flow without any issues. Bug verified.
