缘起

首先看之前安装版本链接及测试 https://cloud.tencent.com/developer/article/1363080 https://cloud.tencent.com/developer/article/1363079 mon ceph0、ceph2、cphe3 osd ceph0、ceph1、ceph2、ceph3 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 0:2.0.0-0undefinedComplete! 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。

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。

报错一

Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

解决方案

报错二

No data was received after 300 seconds, disconnecting...

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
[root@idcv-ceph0 ceph]# cat /etc/yum.repos.d/ceph.repo

7、在Kraken版本里，曾介绍过有一个Ceph管理器，在Luninous版本之后，这个ceph-mgr进程是日常操作必须的，而在Kraken版本时可选的。所以我的Jewel集群里没有这个管理区，在这里我们必须要安装它：

    usage:   296 GB used, 84816 MB / 379 GB avail
    pgs:     272 active+clean

8、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 Loaded: loaded (/usr/lib/systemd/system/ceph-radosgw.target; enabled; vendor preset: enabled) Active: active since Tue 2018-07-10 18:02:25 CST; 6s ago Jul 10 18:02:25 idcv-ceph1 systemd1: Reached target ceph target allowing to start/stop all ceph-radosgw@.service instances at once. Jul 10 18:02:25 idcv-ceph1 systemd1: 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

                "balancer",
                "dashboard",
                "influx",
                "localpool",
                "prometheus",
                "restful",
                "selftest",
                "status",
                "zabbix"
            ]
        },
        {
            "gid": 44134,
            "name": "idcv-ceph1",
            "available_modules": [

                "dashboard",
                "influx",
                "localpool",
                "prometheus",
                "restful",
                "selftest",
                "status",
                "zabbix"
            ]
        },
        {
            "gid": 44135,
            "name": "idcv-ceph3",
            "available_modules": [
                "balancer",
                "dashboard",
                "influx",

                "prometheus",
                "restful",
                "selftest",
                "status",
                "zabbix"
            ]
        }
    ],
    "modules": [
        "balancer",
        "dashboard",
        "restful",
        "status"
    ],
    "available_modules": [

        "restful",
        "selftest",
        "status",
        "zabbix"
    ],
    "services": {
        "dashboard": "http://idcv-ceph0:7000/"
    }
}

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
  cluster:
    id:     812d3acb-eaa8-4355-9a74-64f2cd5209b3
    health: HEALTH_WARN
            application not enabled on 1 pool(s)

  services:
    mon: 3 daemons, quorum idcv-ceph0,idcv-ceph2,idcv-ceph3
    mgr: idcv-ceph0(active), standbys: idcv-ceph2, idcv-ceph1, idcv-ceph3
    osd: 4 osds: 4 up, 4 in
    rgw: 1 daemon active

  data:
    pools:   12 pools, 272 pgs
    objects: 1785k objects, 97496 MB
    usage:   296 GB used, 84830 MB / 379 GB avail
    pgs:     272 active+clean

  io:
    client:   0 B/s rd, 0 op/s rd, 0 op/s wr

报错
    health: HEALTH_WARN
            application not enabled on 1 pool(s)

解决方案
[root@idcv-ceph0 ceph]# ceph health detail
HEALTH_WARN application not enabled on 1 pool(s)

    osd: 4 osds: 4 up, 4 in
    rgw: 1 daemon active

    pgs:     272 active+clean

  io:
    client:   0 B/s rd, 0 op/s rd, 0 op/s wr

总结

整个升级过程大概1个多小时，主要是结合国内情况否则升级还是比较简单的，另外L版本新增了mgr和dashboard功能，升级完成后测试了对象存储功能和块存储功能都正常。
