sure but that didn't worked since firefly for me.

I did:
# set noout
# ceph stop osd.5
# removed disk
# inserted new disk
# format disk and mount disk
# start mkjournal mkkey mkkfs
# remove old osd auth key add new key

I can start the osd but i never comes up.

It only works for me if i completely remove the osd and create a new one:
ceph osd crush remove osd.5
ceph auth del osd.5
ceph osd rm osd.5

ceph osd create
...
