Hi, I'm busy implementing the volume wiping method of the libvirt storage pool backend and instead of writing to the whole RBD image with zeroes I'm using rbd_discard.
Using a 4MB length I'm starting at offset 0 and work my way through the whole RBD image. A quick try shows me that my partition table + filesystem are gone on the RBD image after I've run rbd_discard. I just want to know if this is sufficient to wipe a RBD image? Or would it be better to fully fill the image with zeroes? -- Wido den Hollander 42on B.V.
