Wido den Hollander commented on CLOUDSTACK-8302:
------------------------------------------------

This seems to be a problem with rados-java as well.

It is hardcoded to 16 RBD snapshots at maximum and crashes otherwise it see=
ms.

> I just build a lab with CloudStack 4.4.2 + CentOS 6.6 KVM + Ceph/RBD 0.80=
.8.
> I deploy an instance on RBD and I create the ROOT volume snapshots. When =
delete a snapshot the UI show OK, but the snapshot of the volume in the RBD=
 pool is still exist.
> And I find the code in com/cloud/hypervisor/kvm/storage/KVMStorageProcess=
or.java:=20
> =E2=80=A6
>     @Override
>     public Answer deleteSnapshot(DeleteCommand cmd) {
>         return new Answer(cmd);
>     }
> =E2=80=A6
> deleteSnapshot() does not be implememented. And I also find the code:
> ...
>     @Override
>     public Answer createTemplateFromSnapshot(CopyCommand cmd) {
>         return null;  //To change body of implemented methods use File | =
Settings | File Templates.
>     }
> ...
> So does createTenokateFromSnapshot(). I just look for it in MASTER branch=
 but not do that yet. Will CloudStack Dev Team plan to do that ? Thanks .
