Hi, I create a image and map it to a virtual machine,and then mkfs and mount it. I want to remove the image from mon server forcely, but it says "Removing image: 99% complete...failed. delete error: image still has watchers This means the image is still open or the client using it crashed. Try again after closing/unmapping it or waiting 30s for the crashed client to timeout." I want to know is there any other way to remove it by force? Thank you. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
