Hi, Thank you for your reply. Yesterday I ran compaction according to the following RedHat document (and deep scrub again). ref. https://access.redhat.com/solutions/5173092 The large omap objects warning in this time looks to be resolved. However, based on our observations so far, it could reoccur within a few days. I'm going to run your script if it happens.
