hello every one ,we found some strange problem in my cloud: one vm-rbd's data overwrite another vm-rbd's data !
our cloud base on kvm + qemu-rbd + ceph, kvm and ceph run on different server.
we downloaded problem vm-rbd's objects and found some object data was changed by another vm.

does anyone has the same problem ?

Hi Jian,

It doesn't sound like this issue is related to RBD or Ceph in any way. If you aren't mapping the same image into two different VMs, there is no way something like this can happen. Perhaps there is a bug in your orchestration layer and one of the VMs was inadvertently launched with another VMs disk? Or perhaps an operator error that resulted in the same?

Also, please note that you are running an unsupported version of Ceph. Luminous release (12.2.*) has been EOL for about two years now.
