Glance upload fails after 2.5 hours

Issue

-I am trying to upload a raw image which is 1TB in size and its failing to upload in glance (CEPH backend) after 2- 2.5 hours. I can see the image created in ceph under images pool. I can upload other images without any issues.

• The same image file when I try to upload in qcow2 format it works fine.
