Hi Swami.
Did not make any difference.
Cheers

can you restart osd.32 and check the status?

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 77898/39433323 objects

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
