documentation around rbd_default_features
Last modified: 2016-03-01 03:22:42 EST
Description of problem:
Can't find any documentation upstream and/or downstream, maybe I missed it. If it does exist need to find where it is.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
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.
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)
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.
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.
Marking this BUG as verified.
