Hi,I often observed now that the recovery/rebalance in Nautilus starts quite
fast but gets extremely slow (2-3 objects/s) even if there are like 20 OSDs
involved. Right now I am moving (reweighted to 0) 16x8TB disks, it's running
since 4 days and since 12h it's kind of stuck now at

osd-max-backfill is at 16 for all OSDs.
Anyone got an idea why rebalance completely stopped?
Thanks
Try to lower sleep options:
osd_recovery_sleep_hdd -> if hdd without RocksDB on NVMe;
osd_recovery_sleep_hybrid -> for hybrid solutions, i.e. RocksDB on NVMe;
osd_recovery_sleep_ssd -> for non rotational devices;
