Re: Migrating data from a Ceph clusters to another

[Eugen Block <eblock@xxxxxx>]

I'm not sure if this is what you need, but I recently tried 'rados  
cppool <source-pool> <dest-pool>' to populate a new test-pool with  
different properties. I simply needed some data in there, and this  
command for me.

Regards,
Eugen
