Hi Ilya,
Hope you are doing great.
Sorry for bugging you. I did not find enough resources for my question. I
would be really helped if you could reply me. My questions are in red
colour.
- layering: layering support:
Kernel: 3.10 and plus, right?
Yes.
- striping: striping v2 support:
What kernel is supporting this feature?
Only the default striping v2 pattern (i.e. stripe unit == object size and stripe count == 1) is supported.
- exclusive-lock: exclusive locking support:
It's supposed to be 4.9. Right?
Yes.
rest the the features below is under development? or any feature is
available in any latest kernel?
- object-map: object map support (requires exclusive-lock):
- fast-diff: fast diff calculations (requires object-map):
- deep-flatten: snapshot flatten support:
- journaling: journaled IO support (requires exclusive-lock):
The former, none of these are available in latest kernels. A separate data pool feature (rbd create --data-pool <EC pool>) is supported since 4.11.

Hello Ilya,
Any rough estimate when rbd journaling will be added to the kernel rbd ? I realize it is a lot of work..
Cheers /Maged
