I just recently installed my first ceph cluster using cephadm and used
the following config file for the bootstrap:
|cat /root/ceph.conf|
|[global]|
|||public| |network = ||192.168||.||30.0||/||24|
|||cluster network = ||192.168||.||41.0||/||24|
|
|
Then:
|cephadm bootstrap -c /root/ceph.conf --mon-ip ||192.168||.||30.11|
|
|
|>> 192.168.30.11 is my bootstrap node <<
|
|
|
|I'm sure you can also change this on a running cluster, but I have no
clue how.

The nodes for have 2 network interfaces: 192.168.1.0/24 for the cluster network, and a 10.10.0.0/16 is the public network. When I bootstrap with cephadm, which Network do I use?
Since clients will need to connect to the monitors, you’ll want to use the "public" network space for the setup. Then you’ll need to specify the cluster network via a configuration modification, which will tell the OSDs to use that network to talk to one another.

Hello,
I want to install Ceph Octopus on Ubuntu 20.04. The nodes for have 2
network interfaces: 192.168.1.0/24 for the cluster network, and a
10.10.0.0/16 is the public network. When I bootstrap with cephadm, which
Network do I use? That means, do i use cephadm bootstrap --mon-ip
192.168.1.1 or do I have to use the other network?
When adding the other host with ceph orch, which network I have to use:
ceph orch host add ceph03i 192.168.20.2 … (or the 10.10 network)
Thanks, Erich
