这是Luminous的第一个发布候选版本，它是下一个长期稳定版本。

Ceph Luminous 将成为下一代长期稳定版本系列的基础。自 Kraken (v11.2.z) 和 Jewel (v10.2.z) 以来，它进行了重大更改。

与 Kraken 相比的主要变化

• 常规:

  • Ceph 现在有一个简单、内置的基于 Web 的仪表板，用于监控集群状态。

• RADOS:

  • BlueStore:
    • ceph-osd 的新的 BlueStore 后端现在稳定，并且是新创建的 OSD 的新默认设置。BlueStore 通过直接管理物理 HDD 或 SSD 而无需使用 XFS 等中间文件系统来管理每个 OSD 存储的数据。这提供了更高的性能和功能。
    • BlueStore 支持存储的所有数据的完整数据和元数据校验和。
    • BlueStore 支持使用 zlib、snappy 或 LZ4 进行内联压缩。（Ceph 还支持用于 RGW 压缩的 zstd，但出于性能原因，不推荐将 zstd 用于 BlueStore。）
  • 纠删码池现在完全支持覆盖写入，允许它们与 RBD 和 CephFS 一起使用。阅读有关 EC 覆盖写入的更多信息。
  • ceph-mgr:
    • 有一个新的守护程序，ceph-mgr，它是任何 Ceph 部署中必需的一部分。尽管当 ceph-mgr 关闭时 IO 可以继续，但指标不会刷新，并且某些与指标相关的调用（例如 ceph df）可能会阻塞。我们建议部署多个 ceph-mgr 实例以提高可靠性。请参阅下面的`升级`_说明。
    • ceph-mgr 守护程序包括一个基于 REST 的管理 API。该 API 仍处于试验阶段且功能有限，但将成为未来 Ceph API 管理的基础。
  • 集群的整体可扩展性得到了提高。我们已经成功测试了具有多达 10,000 个 OSD 的集群。
  • 每个 OSD 现在都可以关联一个 device class（例如 hdd 或 ssd），允许 CRUSH 规则轻松地将数据映射到系统中的设备子集。通常不需要手动编写 CRUSH 规则或手动编辑 CRUSH。
  • 您现在可以优化 CRUSH 权重，以在 OSD 之间保持近乎完美的数据分布。
  • 还有一个新的 upmap 异常机制，允许单个 PG 四处移动以实现完美分布（这需要 luminous 客户端）。
  • 每个 OSD 现在根据其底层设备是 HDD 还是 SSD 调整其默认配置。通常不需要手动调整。
  • 原型 mclock QoS 队列算法现已可用。
  • 现在有一个回退机制，可以防止 OSD 被无法当前处理 IO 的对象或 PG 的请求过载。
  • 有一个简化的 OSD 替换过程，更加健壮。
  • 您可以使用 ceph features 查询所有连接的守护程序和客户端支持的功能和（表观）版本。
  • 您可以配置要允许连接到集群的最旧的 Ceph 客户端版本，通过 ceph osd set-require-min-compat-client，并且 Ceph 将阻止您启用将破坏与这些客户端兼容性的功能。
  • 一些 sleep 设置，包括 osd_recovery_sleep、osd_snap_trim_sleep 和 osd_scrub_sleep，已重新实现以高效工作。（在某些情况下，这些设置用于解决限制后台工作的问题。）

• RGW:

  • RGW 元数据搜索由 ElasticSearch 提供支持，现在支持通过 RGW 本身服务于最终用户请求，并且还支持自定义元数据字段。创建了一种查询语言和一组 RESTful API，以便用户能够按其元数据搜索对象。还添加了允许控制自定义元数据字段的新 API。
  • RGW 现在支持动态存储桶索引分片。随着存储桶中对象数量的增加，RGW 将自动响应地重新分片存储桶索引。不需要用户干预或存储桶大小容量规划。
  • RGW 引入了上传对象的服务器端加密，具有三种加密密钥管理选项：自动加密（仅推荐用于测试设置）、类似于 Amazon SSE-C 规范的客户提供的密钥，以及通过使用外部密钥管理服务 (Openstack Barbician) 类似于 Amazon SSE-KMS 规范。
  • RGW 现在具有初步的类似 AWS 的存储桶策略 API 支持。目前，策略是表达一系列新授权概念的一种方式。未来，它将成为 STS 和组策略等附加授权功能的基础。
  • RGW 已经通过使用 rados 命名空间合并了几个元数据索引池。

• RBD:

  • RBD 现在完全稳定地支持纠删码池，通过 rbd create 的新 --data-pool 选项。
  • RBD 镜像的 rbd-mirror 守护程序现在具有高可用性。我们建议部署多个 rbd-mirror 实例以提高可靠性。
  • 默认的 'rbd' 池在集群创建期间不再自动创建。此外，当未指定池时，rbd CLI 使用的默认池名称可以通过新的 rbd default pool = 覆盖配置选项。
  • 通过新的 rbd trash CLI 命令提供延迟图像删除的初始支持。即使是那些被克隆主动使用的图像，也可以移动到回收站并在以后删除。
  • 新的池级别 rbd mirror pool promote 和 rbd mirror pool demote 命令，用于批量提升/降级池内的所有镜像图像。
  • 镜像现在可以选择性地支持通过 rbd mirroring replay delay = 可配置的复制延迟配置选项。
  • 改进了启用对象映射功能时的丢弃处理。
  • rbd CLI import 和 copy 命令现在检测到稀疏并保留稀疏区域。
  • 快照现在将包含创建时间戳

• CephFS:

  • 多个活动 MDS 守护进程现在被认为是稳定的。可以在活动的 CephFS 文件系统上向上或向下调整活动 MDS 服务器的数量。
  • CephFS 目录碎片现在是稳定的，并且在新文件系统上默认启用。要在现有文件系统上启用它，请使用 "ceph fs set <fs_name> allow_dirfrags"。大型或非常繁忙的目录会被分片并（可能）自动分布到多个 MDS 守护程序上。
  • 可以显式地将目录子树固定到特定的 MDS 守护进程，在自动负载平衡不理想或无效的情况下。

• 杂项:

  • 现在正在为 Debian Stretch 构建发布包。我们现在为其构建的发行版包括

    • CentOS 7 (x86_64 和 aarch64)
    • Debian 8 Jessie (x86_64)
    • Debian 9 Stretch (x86_64)
    • Ubuntu 16.04 Xenial (x86_64 和 aarch64)
    • Ubuntu 14.04 Trusty (x86_64)请注意，QA 仅限于 CentOS 和 Ubuntu (xenial 和 trusty)。

  • CLI 更改:

    • ceph -s 或 ceph status 命令具有全新的外观。
    • ceph {osd,mds,mon} versions 汇总了正在运行的守护程序的版本。
    • ceph {osd,mds,mon} count-metadata类似地，通过 ceph {osd,mds,mon} metadata 命令，它会制表任何其他可见的守护程序元数据。
    • ceph features 总结了连接的客户端和守护进程的功能和版本。
    • ceph osd require-osd-release取代了旧的 require_RELEASE_osds 标志。
    • ceph osd pg-upmap, ceph osd rm-pg-upmap, ceph osd pg-upmap-items, ceph osd rm-pg-upmap-items 可以显式管理 upmap 项
    • ceph osd getcrushmap 返回 crush map 版本号到 stderr，ceph osd setcrushmap [version] 仅当版本匹配时才会注入更新的 crush map。这允许 crush map 在离线更新后重新注入到集群中，而无需担心破坏正在进行的变化（例如，由新添加的 osd 或其他管理员的更改）。
    • ceph osd create 已替换为 ceph osd new。对于大多数用户来说，这应该被 ceph-disk 等面向用户的工具隐藏。
    • ceph osd destroy 将标记一个 OSD 已销毁，并删除其 cephx 和 lockbox 密钥。但是，OSD id 和 CRUSH map 条目将保留在原位，允许 id 被替换设备重用，并且数据重新平衡最少。
    • ceph osd purge 将删除集群中 OSD 的所有痕迹，包括其 cephx 加密密钥、dm-crypt lockbox 密钥、OSD id 和 crush map 条目。
    • ceph osd ls-tree将输出给定 CRUSH 名称（如主机或机架名称）下的 OSD id 列表。这对于应用于整个子树的更改很有用。例如，ceph osd down `ceph osd ls-tree rack1`。
    • ceph osd {add,rm}-{noout,noin,nodown,noup} 允许将 noout、nodown、noin 和 noup 标志应用于特定的 OSD。
    • ceph log last [n] 将输出集群日志的最后 n 行。
    • ceph mgr dump 将转储 MgrMap，包括当前活动的 ceph-mgr 守护进程和任何待机守护进程。
    • ceph osd crush swap-bucket将交换层次结构中两个 CRUSH 存储桶的内容，同时保留存储桶的 ID。这允许替换整个设备子树（例如，用新映像的 BlueStore OSD 替换 FileStore OSD 的整个主机），而不会中断数据在相邻设备上的分布。
    • ceph osd set-require-min-compat-client配置集群需要支持的最旧的客户端版本。如果更改此设置会违反此设置，其他更改（如 CRUSH 可调参数）将失败。如果当前连接到集群的客户端版本早于指定的版本，则更改此设置也会失败。
    • ceph config-key dump 打印 config-key 条目及其内容。（现有的 ceph config-key ls 仅打印键名，不打印值。）
    • ceph osd set-{full,nearfull,backfillfull}-ratio 设置集群范围内的各种完整阈值比率（当集群拒绝 IO 时，当集群警告即将达到完整时，当 OSD 将延迟将 PG 重新平衡到自身时，分别）。
    • ceph osd reweightn 将在单个命令中指定多个 OSD 的 reweight 值。这等同于一系列 ceph osd reweight 命令。
    • ceph crush class {create,rm,ls} 管理新的 CRUSH 设备类功能。ceph crush set-device-class将为特定设备设置类。
    • ceph mon feature list 将列出 MonMap 中记录的监视器功能。ceph mon feature set 将设置一个可选功能（目前尚不存在）。

与 Jewel 相比的主要变化

• RADOS:

  • 我们现在默认使用 AsyncMessenger (ms type = async)，而不是传统的 SimpleMessenger。最明显的区别是我们现在使用固定大小的线程池进行网络连接（而不是 SimpleMessenger 的每个套接字两个线程）。
  • 现在几乎可以立即检测到某些 OSD 故障，而以前必须等待心跳超时（默认为 20 秒）过期。这可以防止在主机保持运行但 ceph-osd 进程不再运行的故障情况下，IO 长时间阻塞。
  • 编码的 OSDMap 大小已减小。
  • OSD 现在在恢复或重新平衡进行时会停止擦除。

• RGW:

  • RGW 现在支持 S3 多部分对象 copy-part API。
  • 现在可以离线重新分片现有的存储桶。离线存储桶重新分片当前需要停止特定存储桶的所有 IO（尤其是写入）。（有关自动在线重新分片，请参见 Luminous 上面的新功能。）
  • RGW 现在支持对象的数据压缩。
  • Civetweb 版本已升级到 1.8
  • 现在支持 Swift 静态网站 API（之前已添加 S3 支持）。
  • 已添加 S3 存储桶生命周期 API。请注意，目前它仅支持对象过期。
  • 已为 LDAP 身份验证实现添加了自定义搜索过滤器支持。
  • 已为 RGW NFS 网关添加了 NFS 版本 3 的支持。
  • 已为 librgw 创建了一个 Python 绑定。

• RBD:

  • rbd-mirror 守护进程现在支持将动态图像功能更新和从主图像到非主图像的图像元数据键/值对复制。
  • 可以可选地将图像快照的数量限制为可配置的最大值。
  • rbd Python API 现在支持异步 IO 操作。

• CephFS:

  • • libcephfs 函数定义已更改以启用正确的 uid/gid 控制。库版本已增加以反映接口更改。
      • 待机重放 MDS 守护进程现在在执行删除操作的工作负载上消耗更少的内存。
      • Scrub 现在可以修复回溯，并使用发现的错误填充 damage ls。
      • cephfs-data-scan 的新 pg_files 子命令可以识别受损坏或丢失的 RADOS PG 影响的文件。
      • “failing to respond to cache pressure”（未能响应缓存压力）的误报警告已修复。
