Re: [ceph-users] Fwd: Re: (no subject)

Hello, Can you explain how you do this procedure? I have the same problem with the large images and snapshots. This is what I do: # qemu-img convert -f qcow2 -O raw image.qcow2 image.img # openstack image create image.img But the image.img is too large. Thanks, Fran. 2016-07-13 8:29
