Try and check the xfs fragmentation factor on your „old“ osds.
$ xfs_db -c frag -r /dev/sdX
and see if it’s incredible high.

It's a little worse, but not much:
root@r-ch106:~# xfs_db -c frag -r /dev/sda1
actual 397955, ideal 324744, fragmentation factor 18.40%
root@r-ch106:~# xfs_db -c frag -r /dev/sdb2
actual 378729, ideal 324349, fragmentation factor 14.36%
root@r-ch105:~# xfs_db -c frag -r /dev/sdb2
actual 382831,
This is probably LevelDB being slow. The monitor has some options to
compact the store on startup and I thought the osd handled it
automatically, but you could try looking for something like that and see if
it helps.

Hi guys,
I'm using ceph for a long time now, since bobtail. I always upgraded every few
weeks/ months to the latest stable
release. Of course I also removed some osds and added new ones. Now during the
last few upgrades (I just upgraded from
80.6 to 80.8) I noticed that old osds take much
Does deleting/reformatting the old osds improve the performance?

I'd guess so, but that's not what I want to do ;)
