I got quite a bit of info from Josh, and I've completely restructured the guide. I think their may be some need for formatting work on it though.

Fixed the formatting issue.

Comment 4 Tanay Ganguly 2016-02-04 09:20:24 UTC

John,
I think the default rbd format is still 1 ( In document i am seeing default as 2)

#sudo rbd create Tanay-RBD/taa --size 9812

#sudo rbd -p Tanay-RBD --image taa info
rbd image 'taa':
        size 9812 MB in 2453 objects
        order 22 (4096 kB objects)
        block_name_prefix: rb.0.3fd4a7.238e1f29
        format: 1

rbd_default_format
Description
     The default format (2) if no other format is specified. Format 1 is the original format for a new image, which is compatible with all versions of librbd and the kernel module, but does not support newer features like cloning. Format 2 is supported by librbd and the kernel module since version 3.11 (except for striping). Format 2 adds support for cloning and is more easily extensible to allow more features in the future.
Type

    Integer
Default

    2

Comment 6 John Wilkins 2016-02-09 19:46:39 UTC

I've verified that the default format is 1 for this release. It will be 2 in Infernalis and beyond. Be sure to revisit this matter in RHCS 2.0.
