No update for a while, didn't make it in time for 4.5, closing Might be solved already by the fix for bz 2068104 but we're not sure and as it seems to be a valid scenario in an area that we have been working on lately, we'd like to give it a try and see if it still happens We discussed this offline and agreed that the way to go is to block snapshot removal while there is an ongoing backup Verified. Snapshot removal is blocked with the proper error while there is an ongoing backup. Versions: engine-4.5.1.2-0.11.el8ev vdsm-4.50.1.3-1.el8ev.x86_64 |
Description of problem: The image transfer fails if the user tries to download an incremental backup that was created for a RAW disk with a snapshot (that allows to mark the disk as backup enabled) and deleted a snapshot before the download. Version-Release number of selected component (if applicable): ovirt-4.4.5 vdsm-4.40.50.10-1.el8ev.x86_64 ovirt-imageio-daemon-2.1.1-1.el8ev.x86_64 libvirt-daemon-6.6.0-13.2.module+el8.3.1+10483+85317cf0.x86_64 qemu-kvm-5.1.0-21.module+el8.3.1+10464+8ad18d1a.x86_64 How reproducible: 1. Create a VM with RAW disk 2. take a snapshot 3. Enable incremental backup option for the RAW disk 4, Make a full backup 5. Make an incremental backup 6. Delete the snapshot 7. Try to download the incremental or the full backup. Actual results: Download failed due to missing ticket Expected results: A proper error should be raised.
