Hi, 
 
last week I upgraded our ceph to 14.2.5 (from 14.2.4) and either during 
the procedure or shortly after that, some osds crashed. I re-initialised 
them and that should be enough to fix everything, I thought. 
 
I looked a bit further and I do see a lot of lines like this (which are 
worrying I suppose): 
 
ceph.log:2020-01-10 10:06:41.049879 mon.cephmon3 (mon.0) 234423 : 
cluster [DBG] osd.97 reported immediately failed by osd.67 
 
osd.109 
osd.133 
osd.139 
osd.111 
osd.38 
osd.65 
osd.38 
osd.65 
osd.97 
 
Now everything seems to be OK, but the WARN status remains. Is this a 
"feature" of 14.2.5 or am I missing something? 
 
Below the output of `ceph -s` 
 
Cheers
