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 detailcrush 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 dump_stuck uncleanTo 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 # ceph pg 5.306 query { "state": "active+remapped+backfill_toofull", "snap_trimq": "[]", "epoch": 1054, "up": [ 44, 60, 26 ], "acting": [ 44, 7, 59 ], "backfill_targets": [
