After that, the flapping started again :

2019-10-30 12:55:56.714029 mon.r730xd1 [WRN] Health check update: 2 osds down (OSD_DOWN)
Setting "norecover" flag allow these 2 OSDs to recover up state and
limit the flapping states and many backfills.
In both osd.27 and osd.38 logs, i still find these logs before one

More informations about this object (0c16b76b8b4567.000000000001426e)
from pg 2.1d9 :
ceph osd map rbd rbd_data.0c16b76b8b4567.000000000001426e
osdmap e194356 pool 'rbd' (2) object 'rbd_data.0c16b76b8b4567.000000000001426e' -> pg 2.181de9d9 (2.1d9) -> up ([27,30,38], p27) acting ([30,25], p30)
I also checked the logs of all OSDs already done and got the same logs
about this object :
* osd.4, last time : 2019-10-10 16:15:20
* osd.32, last time : 2019-10-14 01:54:56
* osd.33, last time : 2019-10-11 06:24:01
* osd.34, last time : 2019-10-18 06:24:26
* osd.20, last time : 2019-10-27 18:12:31
* osd.28, last time : 2019-10-28 12:57:47
No matter that the data came from osd.25 or osd.30, i have the same
error. It seems this PG|object try to recover an healthy state but
shutdown my OSDs one by one…

This PG 2.1d9 is "only" marked as : "active+undersized+degraded+remapped+backfill_wait", not inconsistent…
Everything i got from PG 2.1d9 (query, list_missing,
ceph-objectstore-tool list,…) is available here :
https://cloud.ipr.univ-rennes1.fr/index.php/s/BYtuAURnC7YOAQG?path=%2Fpg.2.1d9
But nothing looks suspicious to me…
I also separated the logs from the last error on osd.27 and it's
reboot ("only" ~22k lines ^^) :
https://cloud.ipr.univ-rennes1.fr/index.php/s/BYtuAURnC7YOAQG/download?path=%2F&files=ceph-osd.27.log.last.error.txt
Is anybody understand these logs or do i have to leave with this damned
object ? ^^
