My cluster was throwing warning Legacy BlueStore stats reporting detected and we could just not abide that.

Here's a simple way to upgrade:

cd /var/lib/ceph/osd
ls                                   # note your osd numbers

ceph osd set noout

for n in 7 8 9 10 11 12 ; do 
  systemctl stop ceph-osd@$n.service; 
  ceph-bluestore-tool repair --path ceph-$n; 
  systemctl start ceph-osd@$n.service; 
  systemctl status ceph-osd@$n.service;
done

# I like to wait until the cluster goes back to green 
# before doing the same on the next host

ceph osd unset noout
