Hi Arun, How did you end up with a 'working' cluster with so many pgs per OSD?
"too many PGs per OSD (2968 > max 200)" To (temporarily) allow this kind of pgs per osd you could try this: Change these values in the global section in your ceph.conf: mon max pg per osd = 200 osd max pg per osd hard ratio = 2 It allows 200*2 = 400 Pgs per OSD before disabling the creation of new pgs. Above are the defaults (for Luminous, maybe other versions too) You can check your current settings with: ceph daemon mon.ceph-mon01 config show |grep pg_per_osd Since your current pgs per osd ratio is way higher then the default you could set them to for instance: mon max pg per osd = 1000 osd max pg per osd hard ratio = 5 Which allow for 5000 pgs per osd before disabling creation of new pgs. You'll need to inject the setting into the mons/osds and restart mgrs to make them active. ceph tell mon.* injectargs ‘--mon_max_pg_per_osd 1000’ ceph tell mon.* injectargs ‘--osd_max_pg_per_osd_hard_ratio 5’ ceph tell osd.* injectargs ‘--mon_max_pg_per_osd 1000’ ceph tell osd.* injectargs ‘--osd_max_pg_per_osd_hard_ratio 5’ restart mgrs Kind regards, Caspar Op vr 4 jan. 2019 om 04:28 schreef Arun POONIA < arun.poo...@nuagenetworks.net>: > Hi Chris, > > Indeed that's what happened.
