Hi cephers,
Had the same issue too. But the command "rbd feature disable" not
working to me.
Any comment will be appreciated.
$sudo rbd feature disable timg1 deep-flatten fast-diff object-map
exclusive-lock
rbd: failed to update image features: (22) Invalid argument
2016-04-21 15:53:10.260671 7f95ff5d9d80 -1 librbd: failed to update
features: (22) Invalid argument
Best wishes,
Mika
