缘起
首先看之前安装版本链接及测试

rgw ceph1
deploy ceph0
之前在Centos7.5上测试了Jewel版本的集群，随着对Ceph了解深入，计划线上运行比较新的LTS版本Ceph集群，最终选择了Luminous版本。
本来计划重新部署Luminous版本，看到这是测试环境数据丢失风险小就想尝试升级Jewel版本到Luminous版本，由于之前是Yum安装的根据之前经验原理是更新二进制文件，最后重启服务即可。看介绍文档升级步骤比较简单，但是测试中发现国内用户肯定会遇到一个坑，升级过程中会自动修改yum源到国外的站点，由于网络延迟大300s反应不及时会自动断开连接停止升级服务，故后续的操作我改成了国内源，并找出rpm包手工升级，由于本身有依赖关系故最终就收到yum install ceph ceph-radosgw即可全部升级所有的ceph包，最后重启相关服务即完成升级，最终数据没有丢失，各个功能也正常。
升级过程
参照官方的升级指南一步一步的小心操作，要注意，升级时候要确保系统是健康运行的状态。
1、登录，确认sortbitwise是enabled状态：
[root@idcv-ceph0 yum.repos.d]# ceph osd set sortbitwise
set sortbitwise
2、设置noout标志，告诉Ceph不要重新去做集群的负载均衡，虽然这是可选项，但是建议设置一下，避免每次停止节点的时候，Ceph就尝试通过复制数据到其他可用节点来重新平衡集群。
[root@idcv-ceph0 yum.repos.d]# ceph osd set noout
set noout
3、升级时，可以选择手工升级每个节点，也可以使用使用Ceph-deploy实现自动升级。如果选择手动升级，在CentOS系统里，你需要先编辑Ceph yum repo获取新的Luminous版本来替换老版本Jewel，这就需要一个简单的文本替换操作：
[root@idcv-ceph0 yum.repos.d]# sed -i 's/jewel/luminous/' /etc/yum.repos.d/ceph.repo
4、使用Ceph-deploy可以实现一个命令完成集群的自动升级
[root@idcv-ceph0 yum.repos.d]# yum install ceph-deploy python-pushy
Running transaction
Updating : ceph-deploy-2.0.0-0.noarch 1/2
Cleanup : ceph-deploy-1.5.39-0.noarch 2/2
Verifying : ceph-deploy-2.0.0-0.noarch 1/2
Verifying : ceph-deploy-1.5.39-0.noarch 2/2
Updated:
ceph-deploy.noarch 0:2.0.0-0
Complete!
[root@idcv-ceph0 yum.repos.d]# rpm -qa |grep ceph-deploy
ceph-deploy-2.0.0-0.noarch
5、一旦Ceph-deploy升级完成，首先要做的是在同一台机器上升级Ceph。 执行这步之前先解决下面两个报错，先安装缺少的包，在执行ceph-deploy
发现从这个时候开始按照官网的步骤在国内行不通了，主要原因是yum源改成了国外的网速达不到，后续就是手工升级结合官网步骤了。

报错二

解决方案
另外需要修改ceph源为国内yum源，比如阿里yum,否则会报错No data was received after 300 seconds, disconnecting...
[root@idcv-ceph0 cluster]# sed -i 's#download.ceph.com#mirrors.aliyun.com/ceph#g' /etc/yum.repos.d/ceph.repo
但是命令会自动改成国外源，这里的解决方案是rpm -qa |grep cphe相关，修改成国内yum源后直接手动安装yum install或者使用ceph-deploy install服务

pgs: 272 active+clean8、重启osd
前题是所有节点都修改了国内L版本yum源第6步骤又介绍，执行了yum -y install ceph ceph-radosgw，他会升级二进制文件
[root@idcv-ceph0 ceph]#systemctl restart ceph-osd.target
[root@idcv-ceph0 ceph]# ceph versions
{
"mon": {
"ceph version 12.2.5 (cad919881333ac92274171586c827e01f554a70a) luminous (stable)": 3
},
"mgr": {
"ceph version 12.2.5 (cad919881333ac92274171586c827e01f554a70a) luminous (stable)": 4
},
"osd": {
"ceph version 12.2.5 (cad919881333ac92274171586c827e01f554a70a) luminous (stable)": 4
},
"mds": {},
"overall": {
"ceph version 12.2.5 (cad919881333ac92274171586c827e01f554a70a) luminous (stable)": 11
}
}
9、现在所有的组件都是最新的12.5版本了，我们可以禁止Luminous版本之前的OSD，运行Luminous的独有功能：
[root@idcv-ceph0 ceph]# ceph osd require-osd-release luminous
recovery_deletes is set
这也意味着现在只有Luminous节点才能加入这个集群了。
10、rgw服务也需要重启在ceph1上
[root@idcv-ceph1 system]# systemctl restart ceph-radosgw.target
[root@idcv-ceph1 system]# systemctl status ceph-radosgw.target
● ceph-radosgw.target - ceph target allowing to start/stop all ceph-radosgw@.service instances at once

Jul 10 18:02:25 idcv-ceph1 systemd[1]: Starting ceph target allowing to start/stop all ceph-radosgw@.service instances at once.
11、启动dashboard
[root@idcv-ceph0 ceph]# rpm -qa |grep mgr
ceph-mgr-12.2.5-0.el7.x86_64
[root@idcv-ceph0 ceph]# ceph mgr module enable dashboard
[root@idcv-ceph0 ceph]# ceph mgr dump

12、最后一步，禁止noot，以后集群就可以在需要的时候自己做负载均衡了：
[root@idcv-ceph0 ceph]# ceph osd unset noout
noout is unset
[root@idcv-ceph0 ceph]# ceph -s
