一个RGW环境的更新，ceph 12.2.12升级到14.2.4流程，跳过中间的13版本。注意：升级很危险，操作需谨慎。升级没有后悔药，本人不承担任何因升级及相关操作导致的任何数据丢失风险。

yum准备

yum源里面将旧的

https://mirrors.aliyun.com/ceph/rpm-luminous/el7/x86_64/

替换为

https://mirrors.aliyun.com/ceph/rpm-nautilus/el7/x86_64/

之后更新yum源信息，使用install即可完成二进制包的升级。

yum clean all
yum makecache
yum install ceph ceph-radosgw

更新服务

软件版本升级以后还要使用下面的命令依次，重启MON，MGR，OSD，最后是RGW

systemctl stop ceph-mon@*
systemctl stop ceph-mgr@*
systemctl stop ceph-osd@*
systemctl stop ceph-radosgw@*

修复异常

升级后出现“Legacy BlueStore stats reporting”和“ 3 monitors have not enabled msgr2”,两种类型的异常。出现“Legacy BlueStore stats reporting” 是因为底层数据结构发生变化导致。出现“3 monitors have not enabled msgr2” 是因为新版本需要默认开启msgr2的通信模块。

OSD问题修复

[root@demohost-229 supdev]# ceph -s

[root@demohost-229 supdev]# ceph -v

先修复OSD相关的异常，流程为:停OSD服务，执行“ceph-bluestore-tool repair”，之后再启动OSD服务，将所有OSD依次全部这样操作一遍即可。以修复OSD.1 为例

[root@demohost-227 supdev]# systemctl stop ceph-osd@1
[root@demohost-227 supdev]# ls /var/lib/ceph/osd/ceph-1
activate.monmap  block  bluefs  ceph_fsid  fsid  keyring  kv_backend  magic  mkfs_done  osd_key  ready  require_osd_release  type  whoami
[root@demohost-227 supdev]# ceph-bluestore-tool repair --path /var/lib/ceph/osd/ceph-1

repair success

[root@demohost-227 supdev]# systemctl start ceph-osd@1

[root@demohost-227 supdev]# ceph -s

    pgs:     184 active+clean

  io:
    recovery: 367 B/s, 5 objects/s

MGR2问题修复

之后修复mgr2的问题，随便找台机器执行开启命令即可。

[root@demohost-229 supdev]# ceph -s
  cluster:
    id:     a293ad23-f310-480b-ab2a-5629f2aeef45

    mgr: demohost-229(active, since 19m), standbys: demohost-227, demohost-228
    osd: 6 osds: 6 up, 6 in
    rgw: 3 daemons active (demohost-227, demohost-228, demohost-229)

  data:
    pools:   7 pools, 184 pgs
    objects: 279.96k objects, 92 GiB
    usage:   293 GiB used, 3.0 TiB / 3.3 TiB avail
    pgs:     184 active+clean

  io:
    client:   7.1 KiB/s rd, 7 op/s rd, 0 op/s wr
    recovery: 156 B/s, 2 objects/s

[root@demohost-227 tools]# ceph mon enable-msgr2
[root@demohost-227 tools]# ceph  -s
  cluster:
    id:     a293ad23-f310-480b-ab2a-5629f2aeef45
    health: HEALTH_OK

  services:
    mon: 3 daemons, quorum demohost-227,demohost-228,demohost-229 (age 13s)
    mgr: demohost-229(active, since 22m), standbys: demohost-227, demohost-228
    osd: 6 osds: 6 up, 6 in
    rgw: 3 daemons active (demohost-227, demohost-228, demohost-229)

  data:
    pools:   7 pools, 184 pgs
    objects: 279.96k objects, 92 GiB
    usage:   293 GiB used, 3.0 TiB / 3.3 TiB avail
    pgs:     184 active+clean

  io:
    client:   14 KiB/s rd, 0 B/s wr, 13 op/s rd, 10 op/s wr

总结

升级操作不复杂，但是里面会遇上各种奇葩问题，升级尽量控制在小版本的维度，如果是这种跨大版本，老司机都容易翻车，所以一点要谨慎。
