Hi,
I am getting a health warning about many more objects for PG than
average. Seems to be common with RadosGW, where pools other than data
contain very small number of objects.
ceph@ola-s3-stg:/etc/ceph$ ceph health detail
HEALTH_WARN 1 pools have many more objects per pg than average
MANY_OBJECTS_PER_PG 1 pools have many more objects per pg than average
pool s3dev.rgw.buckets.data objects per pg (22675) is more than
84.2937 times cluster average (269)
According to documentation, I should be able to quiet this warning by
setting mon_pg_warn_max_object_skew.
I did try to set this settings to both 0 and 10000 (docs are unclear
about 0 value), but I cannot make this warning disappear.
ceph@ola-s3-stg:/etc/ceph$ ceph tell mon.* injectargs
'--mon_pg_warn_max_object_skew 0'
mon.olaxsa-cephmon00: injectargs:
mon.olaxsa-cephmon01: injectargs:
mon.olaxsa-cephmon02: injectargs:
ceph@ola-s3-stg:/etc/ceph$ ceph health
HEALTH_WARN 1 pools have many more objects per pg than average
ceph@ola-s3-stg:/etc/ceph$ ceph tell mon.* injectargs
'--mon_pg_warn_max_object_skew 100000'
mon.olaxsa-cephmon00: injectargs:
mon.olaxsa-cephmon01: injectargs:
mon.olaxsa-cephmon02: injectargs:
ceph@ola-s3-stg:/etc/ceph$ ceph health
HEALTH_WARN 1 pools have many more objects per pg than average
I have also tried to set these values in cepf.conf and restart
monitors, but warning is still there
[global]
.....
mon pg warn max object skew = 10000
mon pg warn max object skew = 0
Where should I look next?
Thank you!
ceph version 13.2.4 (b10be4d44915a4d78a8e06aa31919e74927b142e) mimic (stable)
