Description

PR#26226 adds support to "re-sparsify" an RBD image, reclaiming space occupied by zeroed extends. From the man page:

sparsify [--sparse-size *sparse-size*] *image-spec*
  Reclaim space for zeroed image extents. The default sparse size is
  4096 bytes and can be changed via --sparse-size option with the
  following restrictions: it should be power of two, not less than
  4096, and not larger image object size.

It would be useful to offer this feature in the RBD management UI of the dashboard as well.
