Does anyone have this issue before? As research, many people have issue with
rgw.index which related to small small number of index sharding (too many
objects per index).
I also check on this thread
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2019-March/033611.html but
don't found any clues because number of data objects is below 100k per index
and size of objects in rgw.log is 0.
Thanks.

Hi Manuel,
I use version 12.2.8 with bluestore and also use manually index sharding
(configured to 100). As I checked, no buckets reach 100k of objects_per_shard.
here are health status and cluster log
# ceph health detail
HEALTH_WARN 1 large omap objects
LARGE_OMAP_OBJECTS 1 large omap objects
1 large objects found in pool 'default.rgw.log'
Search the cluster log for 'Large omap object found' for more details.
# cat ceph.log | tail -2

Please kindly advise how to remove health_warn message.
Many thanks.
