在ceph quincy版本，即ceph 17版本执行ceph orch host add ceph2添加时，报以下初始化错误

我这里的ceph2在hosts已添加配置，但是在初始化时找不到ceph2地址，官方文档建议最好明确提供主机的IP地址，否则可能会出现失败问题。官方文档地址：https://docs.ceph.com/en/quincy/cephadm/host-management/#cephadm-adding-hosts
所以在添加时，指定节点IP，即
|
1 |
ceph orch host add ceph2 10.10.0.102 |
另外还需要注意密钥是否已经拷贝成功，即
|
1 |
ssh-copy-id -f -i /etc/ceph/ceph.pub root@ceph2 |
如果密钥没有成功拷贝，同样也会出现这个错误
