Hi,
we have a problem with rgw bilogs not being trimmed. This is a multisite with 2 sites on Nautilius 14.2.18, sync status is fine. radosgw-admin bilog list grows especially for buckets with lots of deletes.
So from time to time we get this "large OMAP" warnings, which we easily fix with bilog trim on the affected buckets and deep-scrubbing the PG.
As this is annoying I digged deeper and found these errors occurring 16 times in a batch for random buckets. It seems to affect every bucket. I think this is related to autotrimming which is not working in our case. The command "radosgw-admin bilog autotrim" shows the same messages (and does no trimming):
ERROR: failed to get bucket instance info for .bucket.meta.57d082821ddc45a097b2e3401388e93d/mybucket:feec71ec-408e-4a2b-b3bd-4d214e7c8685.7724460.7
But these are buckets/instances that exists (no shards btw):
radosgw-admin metadata get bucket.instance:57d082821ddc45a097b2e3401388e93d/mybucket:feec71ec-408e-4a2b-b3bd-4d214e7c8685.7724460.7

Does that look familiar to anyone? Any ideas where to dig further?
Best regards,
