Description Tanay Ganguly 2016-06-09 05:40:25 EDT

Description of problem:
Disabling a feature from Master Node, is not getting reflected on Slave Node even after resync completes.

Version-Release number of selected component (if applicable):
rbd-mirror-10.2.1-12.el7cp.x86_64

How reproducible:


Steps to Reproduce:
1. Create an Image without enabling Journal
2. Write some data onto it.
3. Enable Journal
rbd image 'tanay12':
        size 8191 MB in 2048 objects
        order 22 (4096 kB objects)
        block_name_prefix: rbd_data.136a2ae8944a
        format: 2
        features: layering, exclusive-lock, object-map, fast-diff, journaling
        flags: 
        journal: 136a2ae8944a
        mirroring state: enabled
        mirroring global id: b17134d1-087f-48c5-9af4-c52ff035f634
        mirroring primary: true
4. Again start IO on Master Node.
5. While IO is going ON, disable deep-flatten
rbd feature disable RBD/tanay12 deep-flatten --cluster master

Actual results:
On master Node deep-flatten got disabled, but on the Slave Node the image still have deep-flatten enabled.

Master:

rbd image 'tanay12':
        size 8191 MB in 2048 objects
        order 22 (4096 kB objects)
        block_name_prefix: rbd_data.136a2ae8944a
        format: 2
        features: layering, exclusive-lock, object-map, fast-diff, journaling
        flags: 
        journal: 136a2ae8944a
        mirroring state: enabled
        mirroring global id: b17134d1-087f-48c5-9af4-c52ff035f634
        mirroring primary: true

Slave:
rbd image 'tanay12':
        size 8191 MB in 2048 objects
        order 22 (4096 kB objects)
        block_name_prefix: rbd_data.394e12200854
        format: 2
        features: layering, exclusive-lock, object-map, fast-diff, deep-flatten, journaling
        flags: 
        journal: 394e12200854
        mirroring state: enabled
        mirroring global id: b17134d1-087f-48c5-9af4-c52ff035f634
        mirroring primary: false

Expected results:
The Feature should also get disabled in Slave Node.

Dynamic feature updates are not replicated and would be a large effort to implement.
