4. Can I recover the data without backup?
Possibly. If the inconsistency is just that one of the OSDs is storing the
object and another OSD says the object shouldn't exist, that can be recovered
from by working out which one is correct.
Have you manually adjusted the contents of any OSDs? Can you think of anything
you've done that might have triggered this?
I step by step down osd servers until only one remains (hmm, it is not clear how this is
consistent with "pg_size 2"). After one day I step by step up osd servers.
Well if you've got enough space and step down slowly enough all the data will
simply exist on the one up OSD in a degraded form. :)
Is it still marked as inconsistent? If that's really all you did it shouldn't
be, but maybe restarting the cluster would let it fix itself. :/

Yes, I restarted osd server with inconsistent pg and cluster now in
consistent state.
