Hi
I am running openstack kilo on Ubuntu and using ceph as the storage backend
I can resize an instance to a larger flavour say from small to medium but when resizing back from medium to small I get an error that the flavour is too small for the image
Can anyone help me with this ?
Thanks

Hi Concerned,
I suppose this should answer your question very well.
https://ask.openstack.org/en/question/11596/decreasing-instance-disk-size/ (https://ask.openstack.org/en/question...)
basically you need to understand that if a disk is being used, then decreasing it can not be made possible. You can always go for increased size flavour, but if you are looking to decrease it, you should check the disk size being used if it is more that the smaller flavour which youre going to use. Then Openstack will not resize it.

This can be achieved using cinder volumes and creating flavors without rootdisk size i.e rootdisk size should be 0 in the flavor, then you can upsize/downsize your VM CPU and RAM.
