Hello all,
I am buinding my testing cluster with public_network and cluster_network interface. For some reason, the testing cluster need to do peer connection with my colleague's machines so it's better I change my original cluster_network from 172.20.x.x to 10.32.67.x.
Now if I don't want to re-build the whole ceph cluster, I just want to change the interface ip/network setting like:
(it's a 6 nodes CentOS 7.5, 3 mons 3 osds)
1, (all 6) edit /etc/hosts to become
10.32.67.48 cephmon1
10.32.67.49 cephmon2
10.32.67.50 cephmon3
10.32.67.51 cephosd1
10.32.67.52 cephosd2
10.32.67.53 cephosd3
2,(all 6) edit /etc/ceph/ceph.conf
(deploy svr's) /home/cephuser/pescadores/ceph.conf
,,,,
to be
mon_host = 10.32.67.48
cluster_network = 10.32.67.0/24
3, edit individual host's /etc/sysconfig/network-scripts/ifcfg-bond1
to be 10.32.67.x ip
4, reboot
(and forget about firewall and selinux, they are disabled)
what else should I do before the ceph cluster will run on new cluster_network setting?
Thanks in advance
Cheers
Joshua
