I was able to remove the meta objects, but the cluster is still in WARN
state
HEALTH_WARN 1 large omap objects
LARGE_OMAP_OBJECTS 1 large omap objects
1 large objects found in pool 'us-prd-1.rgw.log'
Search the cluster log for 'Large omap object found' for more details.
How do I go about clearing it out? I don't see any other references to
large omap in any of the logs. I've tried restarted the mgr's, the
monitors, and even the osd that reported the issue.
