Description

Sometimes we may want to ceph be in full filled status(ceph has much data in it) for some test cases.
But it takes much time to put several TBs of data.

Could we support generating data in ceph osd nodes locally, without network traffic? So we can populate the cluster fast.

It may work like this:
  1. rados -p <pool-name> generate-data <10TB> <object-prefix>
    When ceph gets this command, it generates objects in every osd node locally according to crush/pg map, all these objects are filled with /dev/zero.

We can download/delete these objects by rados command, just like normal objects.
