As the commands don't take too long, i just had a few slow requests before
the osd was back online. Thanks for the nodown|noout tip.

Done preceded by some dump, get-attrs,… commands. Yeah, not sure about
the real interest, but just to be cautious ^^
The PG still looks inconsistent. I asked for a deep-scrub 2.2ba,
still waiting. `list-inconsistent-obj` and `list-inconsistent-snapset`
returns "No scrub information available for pg 2.2ba" for the moment.
I also tried to manage pg 2.371 with :
ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-27/
'["2.371",{"oid":"rbd_data.0c16b76b8b4567.00000000000420bb","key":"","snapid":22822,"hash":3394498417,"max":0,"pool":2,"namespace":"","max":0}]'
remove
This one doesn't looks inconsistent anymore but i also asked for a
deep-scrup.

Yes… I wait a little bit to see what happens with these commands first
and keep an eye on the cluster health and logs…
