Re: Large OMAP Objects in default.rgw.log pool

["mr. non non" <arnondhc@xxxxxxxxxxx>]

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
