Hello @Muhammad Abdullah,

 

The logs show the API failed to find the snapshot:
03/29 14:02:45:

server-resp:[{"itemNotFound": {"code": 404, "message": "Snapshot a4f9e193-9e84-4721-b4e7-d62190e93cf1 could not be found."}}] resp-size:[111]

 

Looking back earlier in the log, We can see the Snapshot referenced for the disk:

03/29 14:02:04

OpenStackSDKWrapper::CVGlanceQueries::GetImageInfo() - [GLANCE] : Block mapping detail of image [236bb705-21e0-4ecb-8cb5-af074c3f53e3]: [[{"destination_type": "volume", "guest_format": null, "image_id": null, "device_name": "/dev/vda", "no_device": null, "source_type": "snapshot", "volume_type": null, "tag": null, "volume_size": 100, "boot_index": 0, "snapshot_id": "a4f9e193-9e84-4721-b4e7-d62190e93cf1", "volume_id": null, "disk_bus": "virtio", "device_type": "disk", "delete_on_termination": false}

 

So based on the above, I would assume the Snapshot was pruned for some reason. - You might want to check the logs on the Openstack side here.

 

Also please note that for priority issues, it would be best to raise a Support Case at ma.commvault.com. 

 

Best Regards,

Michael
