Hi, I would like to shrink a thin provisioned rbd image which has grown to maximum. 90% of the data in the image is deleted data which is still hidden in the image and marked as deleted.
So I think I can fill the whole Image with zeroes and then qemu-img convert it. So the newly created image should be only 10% of the maximum size. I will do something like qemu-img convert -O raw rbd:pool/origimage rbd:pool/smallimage rbd rename origimage origimage-saved rbd rename smallimage origimage Would this be the best and fastest way or are there other ways to do this ?
