Hi, we have a ceph 17.2.6 with ragosgw and a couple of buckets in it. We use it for backup with lock directly from veeam. After few backups we got HEALTH_WARN 2 large omap objects │····················· [WRN] LARGE_OMAP_OBJECTS: 2 large omap objects │····················· 2 large objects found in pool 'backup.rgw.buckets.index' │····················· Search the cluster log for 'Large omap object found' for more details.

What is causing this ? could we get a bigger threshold avout omap size and ignore safely this warning ? What's the issue?

My guess is that Veeam is using versioned buckets, is that correct? I think this thread has relevant info for you: https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/HFOWJM52D4XX... Gr. Stefan
