[ceph-users] safest way to remove a host from Mimic

Hi guys, I need to remove a host (osd server) from my Ceph Mimic.  First I started to remove every OSD drive one by one with 'ceph osd out' and then 'ceph osd purge'.  After all the drives will be removed from the crush map, I will still have the host empty, without any drive, and with the crush weight = 0. What is the recommend way to remove the host from Ceph : - ceph-deploy purge <hostname> - ceph-deploy purgedata <hostname> - ceph osd crush remove <hostname>   ? Thanks.
