Hi, Goncalo.
Do you set sortbitwise flag during update? If YES, try to unset it. I
faced with same problem when upgrade my ceph cluster from Hummer to
Jewel. Maybe it's your: http://tracker.ceph.com/issues/16113

Hi All...
Today we had a warning regarding 8 near full osd. Looking to the
osds occupation, 3 of them were above 90%. In order to solve the
situation, I've decided to reweigh those first using
ceph osd crush reweight osd.1 2.67719
ceph osd crush reweight osd.26 2.67719
ceph osd crush reweight osd.53 2.67719
Please note that I've started with a very conservative step since
the original weight for all osds was 2.72710.
After some rebalancing (which has now stopped) I've seen that the
cluster is currently in the following state
# ceph health detail
HEALTH_WARN 4 pgs backfill_toofull; 4 pgs stuck unclean;
recovery 20/39433323 objects degraded (0.000%); recovery

osd.53 is near full at 88%
osd.56 is near full at 85%
osd.62 is near full at 87%
crush map has legacy tunables (require bobtail, min is
firefly); see
http://ceph.com/docs/master/rados/operations/crush-map/#tunables
Not sure if it is worthwhile to mention, but after upgrading to
Jewel, our cluster shows the warnings regarding tunables. We still
have not migrated to the optimal tunables because the cluster will
be very actively used during the 3 next weeks ( due to one of the
main conference in our area) and we prefer to do that migration
after this peak period,
I am unsure what happen during the rebalacing but the mapping of
these 4 stuck pgs seems strange, namely the up and acting osds are
different.

# ceph pg map 5.306
osdmap e1054 pg 5.306 (5.306) -> up [44,60,26] acting [44,7,59]
To complete this information, I am also sending the output of pg
query for one of these problematic pgs (ceph pg 5.306 query)
after this email.
What should be the procedure to try to recover those PGS before
continuing with the reweighing?
Than you in advance
Goncalo
