I have been following this thread for a while, and thought I need to 
have 
 "major ceph disaster" alert on the monitoring ;)

Hi,

we have set the PGs to recover and now they are stuck in 
active+recovery_wait+degraded and instructing them to deep-scrub does 
not change anything. Hence, the rados report is empty. Is there a way to 
stop the recovery wait to start the deep-scrub and get the output? I 
guess the recovery_wait might be caused by missing objects. Do we need 
to delete them first to get the recovery going?

	Kevin,

	I just fixed an inconsistent PG yesterday. You will need to figure 
out why they are inconsistent. Do these steps and then we can figure out 
how to proceed.
	1. Do a deep-scrub on each PG that is inconsistent. (This may fix 
some of them)
	2. Print out the inconsistent report for each inconsistent PG. 
`rados list-inconsistent-obj <PG_NUM> --format=json-pretty`
	3. You will want to look at the error messages and see if all the 
shards have the same data.
