v10.2.0 Jewel 发布

2016 年 4 月 21 日 sage

此主要版本将成为下一个长期稳定版本的基础。自 Infernalis (9.2.x) 和 Hammer (0.94.x) 版本以来，发生了许多重大变化，升级过程并非易事。请仔细阅读这些发行说明。

Infernalis 的重大变化 ¶

CephFS:
- 这是 CephFS 宣布稳定的第一个版本！默认禁用了一些功能，包括快照和多个活动 MDS 服务器。
- 修复和灾难恢复工具现已功能完善。
- 包含一个新的 cephfs-volume-manager 模块，它为 OpenStack Manila 和类似项目创建“共享”提供了高级接口。
- 现在实验性地支持在单个集群中运行多个 CephFS 文件系统。
RGW:
- 多站点功能已几乎完全重新架构和重写，以支持任意数量的集群/站点、双向故障转移和主动/主动配置。
- 您现在可以通过 NFS 访问 radosgw 存储桶（实验性）。
- 现在支持 AWS4 身份验证协议。
- 现在支持 S3 请求付费存储桶。
- 新的多租户基础设施提高了与 Swift 的兼容性，后者为每个用户/租户提供单独的容器命名空间。
- 现在支持 OpenStack Keystone v3 API。还有一系列其他 Swift API 小功能和兼容性改进，包括批量删除和 SLO（静态大对象）。
RBD:
- 新增了对集群间 RBD 镜像镜像（异步复制）的支持。这是通过一个 per-RBD 镜像日志实现的，该日志可以流式传输到另一个站点的 WAN 上，以及一个新的 rbd-mirror 守护程序来执行跨集群复制。
- exclusive-lock、object-map、fast-diff 和 journaling 功能可以动态启用或禁用。deep-flatten 功能可以动态禁用，但不能重新启用。
- RBD CLI 已重写，提供特定于命令的帮助和完整的 bash 补全支持。
- RBD 快照现在可以重命名。
RADOS:
- BlueStore 是一个新的 OSD 后端，作为实验性功能包含在内。计划是在 K 或 L 版本中成为默认后端。
- OSD 现在会持久化擦除结果，并提供 librados API 来详细查询结果。
- 我们修改了文档，建议**不要**使用 ext4 作为 Ceph OSD 守护程序的基础文件系统，因为它在支持我们的长对象名称处理方面存在问题。

自 HAMMER 以来的主要变化 ¶

常规:
- Ceph 守护程序现在通过 systemd 管理（Ubuntu Trusty 除外，它仍然使用 upstart）。
- Ceph 守护程序现在以“ceph”用户而不是“root”用户身份运行。
- 在 Red Hat 发行版上，还有一个 SELinux 策略。
RADOS:
- RADOS 缓存层现在可以将写操作代理到基础层，从而无需强制将对象迁移到缓存中即可处理写操作。
- SHEC 纠删编码支持不再被标记为实验性。SHEC 通过额外的存储空间换取更快的修复速度。
- 现在有一个统一的队列（因此具有优先级）的客户端 IO、恢复、擦洗和快照修剪。
- 对低级修复工具（ceph-objectstore-tool）进行了许多改进。
- 内部 ObjectStore API 已经过重大清理，以便为 BlueStore 等新存储后端提供便利。
RGW:
- Swift API 现在支持对象过期。
- 有很多 Swift API 兼容性改进。
RBD:
- rbd du 命令显示实际使用情况（在启用 object-map 时快速）。
- object-map 功能已经进行了许多稳定性改进。
- object-map 和 exclusive-lock 功能可以动态启用或禁用。
- 现在可以存储用户元数据并设置与单个镜像关联的持久 librbd 选项。
- 新的 deep-flatten 功能允许展平克隆及其所有快照。（以前无法展平快照。）
- export-diff 命令现在更快（它使用 aio）。还有一个新的 fast-diff 功能。
- 可以使用后缀指定单位的 --size 参数（例如，--size 64G）。
- 有一个新的 rbd status 命令，目前显示谁打开/映射了镜像。
CephFS:
- 现在可以重命名快照。
- 在管理、诊断和检查和修复工具方面进行了持续改进。
- 客户端缓存状态的缓存和撤销因未使用的 inode 而显著改进。
- ceph-fuse 客户端在 32 位主机上的行为更好。

发行版兼容性 ¶

从 Infernalis 开始，我们放弃了对许多旧发行版的支持，以便我们可以迁移到较新的编译器工具链（例如 C++11）。尽管仍然可以通过安装反向移植的开发工具在旧发行版上构建 Ceph，但我们不再为 ceph.com 构建和发布发行包。

我们现在为以下发行版和架构构建软件包

x86_64
- CentOS 7.x。我们放弃了对 CentOS 6（以及其他 RHEL 6 派生版本，如 Scientific Linux 6）的支持。
- Debian Jessie 8.x。Debian Wheezy 7.x 的 g++ 对 C++11 的支持不完整（并且没有 systemd）。
- Ubuntu Xenial 16.04 和 Trusty 14.04。不再支持 Ubuntu Precise 12.04。
- Fedora 22 或更高版本。
aarch64 / arm64
- Ubuntu Xenial 16.04。

从 INFERNALIS 或 HAMMER 升级 ¶

我们现在建议不要使用 ext4 作为 Ceph OSD 的基础文件系统，尤其是在使用 RGW 或其他使用长 RADOS 对象名称的用户时。有关原因的更多信息，请参阅文件系统建议。
如果您现有的集群使用 ext4 作为 OSD，但仅使用 RBD 和/或 CephFS，则 ext4 的限制不会影响您。在升级之前，请务必在 ceph.conf 中添加以下内容以允许 OSD 启动
osd max object name len = 256 osd max object namespace len = 64
请记住，如果您设置了这些较低的对象名称限制，并且以后决定在此集群上使用 RGW，它将无法存储名称较长的 S3/Swift 对象。此启动检查也可以通过以下选项禁用，尽管不推荐这样做
osd check max object name len on startup = false
自 Infernalis 以来没有重大的兼容性更改。只需升级每个主机上的守护程序并重新启动所有守护程序即可。
rbd CLI 在创建、导入和克隆操作期间不再接受已弃用的“--image-features”选项。应改用“--image-feature”选项。
rbd 旧版镜像格式（版本 1）在 Jewel 版本中已弃用。尝试创建新的版本 1 RBD 镜像将导致警告。Ceph 的未来版本将删除对版本 1 RBD 镜像的支持。
“send_pg_creates”和“map_pg_creates”mon CLI 命令已过时且不再支持。
添加了一个新的配置选项“mon_election_timeout”以专门限制监视器选举过程的最大等待时间，该时间以前受“mon_lease”限制。
使用早于 Firefly (0.80) 版本的 CephFS 文件系统在升级到 Jewel 后必须使用新的“cephfs-data-scan tmap_upgrade”命令。有关更多信息，请参阅 CephFS 文档中的“升级”。
“ceph mds setmap”命令已被删除。
新镜像的默认 RBD 镜像功能已更新为启用以下功能：排他锁、对象映射、fast-diff 和 deep-flatten。这些功能目前不受 RBD 内核驱动程序或旧版 RBD 客户端支持。可以通过 RBD CLI 按镜像禁用它们，或者通过在 Ceph 配置文件中客户端部分添加以下内容将默认功能更新为 Jewel 之前的设置
rbd default features = 1
rbd 旧版镜像格式（版本 1）在 Jewel 版本中已弃用。
升级后，用户应设置“sortbitwise”标志以启用新的内部对象排序顺序
ceph osd set sortbitwise
此标志对于新的对象枚举 API 和 BlueStore 等新后端非常重要。
rbd CLI 不再允许创建名称可能模糊不清的镜像和快照（例如，不允许使用“/”和“@”字符）。可以通过在创建镜像或快照时向 rbd CLI 添加“--rbd-validate-names=false”来暂时禁用验证。也可以通过在 Ceph 配置文件中客户端部分添加以下内容来禁用它
rbd validate names = false

从 HAMMER 升级 ¶

所有集群节点必须首先升级到 Hammer v0.94.4 或更高版本的 v0.94.z 版本；只有这样才能升级到 Jewel 10.2.z。
对于所有支持 systemd 的发行版（CentOS 7、Fedora、Debian Jessie 8.x、OpenSUSE），Ceph 守护程序现在使用本机 systemd 文件管理，而不是旧的 sysvinit 脚本。例如，
systemctl start ceph.target # 启动所有守护程序 systemctl status ceph-osd@12 # 检查 osd.12 的状态
尚未使用 systemd 的主要发行版是 Ubuntu trusty 14.04。（下一个 Ubuntu LTS，16.04，将使用 systemd 代替 upstart。）
Ceph 守护程序现在默认以用户和组 ceph 身份运行。ceph 用户具有 Fedora 和 Debian 分配的静态 UID（也用于 RHEL/CentOS 和 Ubuntu 等派生发行版）。在 SUSE 上，将使用与 Fedora 和 Debian 相同的 UID/GID，**前提是尚未分配**。在不太可能发生首选 UID 或 GID 已分配给其他用户/组的情况下，ceph 将获得动态分配的 UID/GID。
如果您的系统已经有一个 ceph 用户，升级软件包会导致问题。我们建议您在升级之前先删除或重命名现有的“ceph”用户和“ceph”组。
在升级时，管理员有两个选择
1. 将以下行添加到所有主机的 ceph.conf
  setuser match path = /var/lib/ceph/$type/$cluster-$id
  如果守护程序的数据目录仍然由 root 拥有，这将使 Ceph 守护程序以 root 身份运行（即，不放弃权限并切换到用户 ceph）。新部署的守护程序将使用由用户 ceph 拥有的数据创建，并将以减少的权限运行，但升级的守护程序将继续以 root 身份运行。
2. 在升级过程中修复数据所有权。这是首选选项，但工作量更大，而且可能非常耗时。每个主机的过程是
  1. 升级 ceph 包。这将创建 ceph 用户和组。例如
    ceph-deploy install --stable jewel HOST
  2. 停止守护程序。
    service ceph stop # fedora, centos, rhel, debian stop ceph-all # ubuntu
  3. 修复所有权
    chown -R ceph:ceph /var/lib/ceph
  4. 重新启动守护程序。
    start ceph-all # ubuntu systemctl start ceph.target # debian, centos, fedora, rhel
  或者，可以使用单个守护程序类型完成相同的过程，例如仅停止监视器并仅更改 /var/lib/ceph/mon 的所有权。
实验性 KeyValueStore OSD 后端的磁盘格式已更改。在升级使用它的任何测试集群之前，您需要删除任何使用该后端的 OSD。
当达到池配额时，librados 操作现在会无限期地阻塞，就像集群填满时一样。（以前它们会返回 -ENOSPC。）默认情况下，完整的集群或池现在会阻塞。如果您的 librados 应用程序可以优雅地处理 ENOSPC 或 EDQUOT 错误，您可以使用新的 librados OPERATION_FULL_TRY 标志获取错误返回。
librbd 的 rbd_aio_read 和 Image::aio_read API 方法的返回值不再在成功时返回读取的字节数。相反，它在成功时返回 0，在失败时返回负值。
“ceph scrub”、“ceph compact”和“ceph sync force”现已**弃用**。用户应改用“ceph mon scrub”、“ceph mon compact”和“ceph mon sync force”。
‘ceph mon_metadata’ 应改为使用 ‘ceph mon metadata’。无需弃用此命令（自首次引入以来，同一主要版本）。
“osdmaptool”的 –dump-json 选项被 –dump json 取代。
“pg ls-by-{pool,primary,osd}” 和 “pg ls” 命令现在使用 “recovering” 而不是 “recovery”，以将正在恢复的 pg 包含在列出的 pg 中。

从 FIREFLY 升级 ¶

不建议直接从 Firefly v0.80.z 升级。可以直接升级，但并非没有停机时间，因为所有 OSD 必须停止、升级，然后重新启动。我们建议集群首先升级到 Hammer v0.94.6 或更高版本的 v0.94.z 版本；只有这样才能升级到 Jewel 10.2.z 进行在线升级（见下文）。

要直接从 Firefly 进行离线升级，必须在允许任何 Jewel OSD 启动之前停止所有 Firefly OSD 并将其标记为 down。Jewel 监视器强制执行此隔离，因此您应该使用以下升级过程

升级监视器主机上的 Ceph
重新启动所有 ceph-mon 守护程序
设置 noout：
ceph osd set noout
升级所有 OSD 主机上的 Ceph
停止所有 ceph-osd 守护程序
将所有 OSD 标记为 down，例如：
ceph osd down seq 0 1000
启动所有 ceph-osd 守护程序
让集群稳定下来，然后取消设置 noout：
ceph osd unset noout
升级并重新启动任何剩余的守护程序（ceph-mds、radosgw）
