Title: Nova Image Resize Generating Errors Status in OpenStack Compute (nova): Invalid Bug description: Description =========== When flavor disk size is larger than the image size, Nova will try to increase the image disk size to match the flavor disk size. In the process, it will call resize2fs to resize the image disk file system as will for raw-format, but this will generate an error since resize2fs should be executed on a partition block device instead of the whole block device (which includes boot sector, partition table, etc). Steps to Reproduce ================== 1. Set the following configuration for nova-compute: use_cow_images = False force_raw_images = True 2. nova boot --image cirros-0.3.5-x86_64-disk --nic net- id=6f0df6a5-8848-427b-8222-7b69d5602fe4 --flavor m1.tiny test_vm The following error log are generated: Nov 08 14:42:51 devstack01 nova-compute[10609]: DEBUG nova.virt.disk.api [None req-771fa44d-46ce-4486-9ed7-7a89ddb735ed demo admin] Unable to determine label for image <LocalFileImage:{'path': '/opt/stack/data/nova/instances/73b49be7-0b5f-4a9d-a187-bbbf7fd59961/disk', 'format': 'raw'}> with error Unexpected error while running command.
