There is TRIM/discard support and I use it with some success. There are some
details here http://ceph.com/docs/master/rbd/qemu-rbd/ The one caveat I have
is that I've sometimes been able to crash an osd by doing fstrim inside a guest.

Hi,
RBD has had support for sparse allocation for some time now. However, when
using an RBD volume as a virtual disk for a virtual machine, the RBD volume
will inevitably grow until it reaches its actual nominal size, even if the
filesystem in the guest machine never reaches full utilization.
