Documentation #44284
Updated by Sebastian Wagner about 4 years ago
If we don't edit the map when bootstrapping, the CRUSH map has to be edited at runtime, which is non-trivial.
However, there is a workaround by modifying the initial ceph.conf like so:
<pre>
echo -en "[global]\n osd crush chooseleaf type = 0\n" > /root/ceph.conf
cephadm bootstrap -c /root/ceph.conf
</pre>
