Open Stack

Nothing should be downloading files to DevStackOSDomU; they get downloaded straight into dom0 when you create an image.

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

Subject: [xs-devel] Delete the imported VM image to release space -- Sisu

Hi, all:

I am using OpenStack with XenServer. 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).

However, the disk-space is not released. And I cannot find the previously imported image.

I checked the /var/lib/mysql, and also tried to use "du -a /var | sort -n -r | head -n 10" to find the top 10 files, but still cannot find any file larger than 1G.

Can anyone help me with this?

Thanks very much!

Sisu
