Doc Text:
.`ceph-objectstore-tool` command allows manual trimming of the accumulated PG log dups entries Previously, trimming of PG log dups entries was prevented during the low-level PG split operation which is used by the PG autoscaler with far higher frequency than by a human operator. Stalling the trimming of dups resulted in significant memory growth of PG log, leading to OSD crashes as it ran out of memory. Restarting an OSD did not solve the problem as the PG log is stored on disk and reloaded to RAM on startup. With this fix, the `ceph-objectstore-tool` command allows manual trimming of the accumulated PG log dups entries, to unblock the automatic trimming machinery. A debug improvement is implemented that prints the number of dups entries to the OSD's log to help future investigations.
