Unfortunately it doesn't work...<br>
<br>
Here is the error: "Flavor's disk is too small for requested image. Flavor disk is 21474836480 bytes, image is 53687091200 bytes.]."<br>
<br>
This is on an image that was taken when the flavor had root with 50GB and tried to upload it using a flavor of 20GB.<br>
<br>
The filesystem uses around 2-3GB and I had specified with the "--min-disk 5" parameter to be able to spawn on 5GB or more flavors.<br>
<br>
Here is the output from "image show" command<br>

The only thing that I didn't do was to use the "save" command although I don't know if that could make a difference!<br>
<br>
I 've just went to "/var/lib/glance/images" and taken directly from there the file that was corresponding to the image I wanted.<br>
Do you believe that by "saving" it would make any difference??<br>
<br>
Any other ideas that I can try???<br>
<br>

All the best,<br>

Hi Chris!<br>
<br>
Thanks for pointing out the "--min-disk" parameter. I haven't used<br>
that one before.<br>
<br>
I 'll try it out and post back.<br>

You might be able to change it via openstack command, probably<br>
something like 'openstack show image <Id>' / 'openstack image set ??<br>
<id>'<br>
<br>
You can definitely download the image to a file and then upload a new<br>
image, specifying --min-disk. Something like 'openstack image save<br>
--file <file> <id>' and then just 'openstack image create --file<br>
<file> --min-disk <disk size in gb> <image name>'<br>

Hello!<br>
<br>
Let's assume that I have a VM's image that has been taken when the VM was launched with a flavor of 50GB for the root disk.<br>
Now when I try to spawn a new VM out of that image I cannot do it with a flavor that has disk less than 50GB even if the VM itself inside uses only 5GB.<br>
<br>
Is there a way to shrink the image's flavor requirements?<br>
<br>
Best,<br>
<br>
G.<br>
