My Ceph Version is 17.2.5 and all configuration about osd_scrub* are
defaults. I tried some updates on osd-max-backfills but no change.
I have many HDD with NVME for db and all are connected in a 25G network.
Yes, it's the same PG since 4 days.
I got a failure on a HDD and get many days of recovery+backfilling last 2
weeks. Perhaps the 'not in time' warning is related to this.
