Hello,
>From several weeks, i have some OSDs flapping before ending out of the
cluster by Ceph…
I was hoping some Ceph's magic and just gave it sometime to auto heal
(and be able to do all the side work…) but it was a bad idea (what a
surprise :D). Also got some inconsistents PGs, but i was waiting a quiet
health cluster before trying to fix them.
Now that i have more time, i also have 6 OSDs down+out on my 5 nodes
cluster and 1~2 OSDs still flapping from time to time, i asking myself
if these PGs might be the (one ?) source of my problem.
The last OSD error on osd.28 gave these logs :

But i never saw such inconsistent errors and can't find topic related to
my case. Does someone has any clue ? Should i try to fix the PGs first ?
With which method ?
All nodes are on the same version of Ceph Luminous − 12.2.12.
More logs and infos are also available on an OwnCloud share (due to the
size of logs) :
