Today, I will talk to you about how to solve the problem of upload failure due to large mirroring in openstack. Many people may not know much about it. In order to let everyone know more, Xiaobian summarizes the following contents for everyone. I hope you can gain something according to this article.

1. First create a dummy file (0 byte) cd /opt/image/touch dummy2. Then upload the dummy file as a mirror (seconds) glance image-create --name win7 --file /opt/image/dummy --disk-format qcow2 --container-format bare --visibility public --progress3. Query image id+--------------------------------------+| Property | Value |+------------------+--------------------------------------+| checksum | d41d8cd98f00b204e9800998ecf8427e || container_format | bare || created_at | 2018-05-17T01:23:36Z || disk_format | qcow2 || id | f7fbe797-184a-4c5d-ad67-67cb254539a2 || min_disk | 0 || min_ram | 0 || name | win7 || owner | 3bc17302ef9f465ba390fa036a35a34e || protected | False || size | 0 || status | active || tags | [] || updated_at | 2018-05-17T01:23:37Z || virtual_size | None || visibility | public |+--------------------------------------67cb 254539a2 This file cp /opt/image/win7.qcow2 f7fbe797-184a-4c5d-ad67-67cb254539a26. Modify size

Since glance calculates size and md5sum and saves the database when uploading the dummy, it is obviously different from the calculation result of the real mirror.

You can change it by directly modifying the data.
