Comment 5 for bug 1375596

Verified on MOS 6.1 ISO #455

Steps To Verify:
1. Create Glance image with 5 Gb size:
fallocate -l 5G image.img
2. Upload it to the glance:
glance image-create --name "Test1" --is-public True --disk-format raw --container-format bare --file image.img
3. Create Glance image with 70 Gb size:
fallocate -l 70G image2.img
4. Upload it to the glance:
glance image-create --name "Test2" --is-public True --disk-format raw --container-format bare --file image2.img --progress

Observed Result:
We can successfully upload image with 5Gb size but can't upload image with 70 Gb size, we can see the following errors:
