Hi Sisu, Sorry – I understand now. When you upload an image to glance it will get stored in the DevStackOSDomU by default, as that is where Swift is storing it’s data. The data is likely in /opt/stack/data/swift but is likely still owned by the glance service account. Unfortunately by rebooting the machine you caused devstack to restart. It’s very possible that the glance image repository is not maintained between devstack runs – if so, the image could be ‘lost’ within swift.
We typically only use very small virtual machines for testing (which is the primary purpose of the devstack-setup) which is why we have not seen such space used in the DomU.

I just don't know why the disk is full. Here is the process: 1. port self-build image using glance image-create; 2. shutdown machine 3. boot machine up, the disk space is gone, and I don't know how to free it. Thanks.

Why do you think the missing disk space is related to mysql, or to /var?

I am using a pre-build image found in: http://downloads.vmd.citrix.com/OpenStack/ The image file is devstack-havana.xva. This image has a disk size of 40G, I tried to import a self-build 15G image, it worked just fine. When I reboot the machine, the previously imported 15G image is gone (which is expected). stack@DevStackOSDomU:~$ glance image-list +--------------------------------------+---------------------------------+-------------+------------------+----------+--------+ | ID | Name | Disk Format | Container Format | Size | Status | +--------------------------------------+---------------------------------+-------------+------------------+----------+--------+ | 22bcc4ed-c412-495d-995c-bdfc571e0991 | cirros-0.3.0-x86_64-disk | vhd | ovf | 9220018 | active | | 93aefd5f-3e75-4969-a013-e49e9c85163d | cirros-0.3.1-x86_64-uec | ami | ami | 25165824 | active | | 4d63a0d5-91e0-4fcb-944c-9fa25e7549e8 | cirros-0.3.1-x86_64-uec-kernel | aki | aki | 4955792 | active | | d8c961b7-5fe1-4520-8fa3-8bba97729eeb | cirros-0.3.1-x86_64-uec-ramdisk | ari | ari | 3714968 | active | +--------------------------------------+---------------------------------+-------------+------------------+----------+--------+ However, the disk-space is not released.
