Our bugfix from earlier this year was published in the ceph quincy release 17.2.4.
Trimming of PGLog dups is now controlled by size instead of the version. This fixes the PGLog inflation issue that was happening when online (in OSD) trimming jammed after a PG split operation. Also, a new offline mechanism has been added: ceph-objectstore-tool now has a trim-pg-log-dups op that targets situations where an OSD is unable to boot due to those inflated dups. If that is the case, in OSD logs the “You can be hit by THE DUPS BUG” warning will be visible. Relevant tracker: https://tracker.ceph.com/issues/53729"
