Hello Samuel, Why you want to do that? Just remove the rbd - as long your Image is distributet over random OSDs there is no way to recovery a delete Image.. ...2 cents Mehmet Am 12. Mai 2020 12:55:22 MESZ schrieb "huxiaoyu@horebdata.cn" <huxiaoyu@horebdata.cn>:

Hi， Ceph folks,

Is there a rbd command, or any other way, to zero out rbd images or volume? I would like to write all zero data to an rbd image/volume before remove it.

Any comments would be appreciated.

best regards,
