Here is what I did - bash history:
> 1897 for n in 6 7 14 15 16 17 18 19 3 9 10 11 12 20; do ceph osd down osd.$n; done> 1920 for n in 6 7 14 15 16 17 18 19 3 9 10 11 12 20; do ceph osd out
osd.$n; done
> 1921 for n in 6 7 14 15 16 17 18 19 3 9 10 11 12 20; do ceph osd down osd.$n; done
> 1923 for n in 6 7 14 15 16 17 18 19 3 9 10 11 12 20; do systemctl stop ceph-osd@$n.service; done
> 1925 for n in 6 7 14 15 16 17 18 19 3 9 10 11 12 20; do ceph osd crush remove osd.${n}; done
> 1926 for n in 6 7 14 15 16 17 18 19 3 9 10 11 12 20; do ceph auth del osd.${n}; done
> 1927 for n in 6 7 14 15 16 17 18 19 3 9 10 11 12 20; do ceph osd rm ${n}; done
I assume that I did the right steps...
