12.2.6 has a regression. See "v12.2.7 Luminous released" and all of the related disaster posts. Also in the release nodes for .7 is a bug disclosure for 12.2.5 that affects rgw users pretty badly during upgrade. You might take a look there.

_______________________________________________I just upgraded our cluster to 12.2.6 and now I see this warning about 1 large omap object. I looked and it seems this warning was just added in 12.2.6. I found a few discussions on what is was but not much information on addressing it properly. Our cluster uses rgw exclusively with just a few buckets in the .rgw.buckets pool. Our largest bucket has millions of objects in it.
Any thoughts or links on this?
