我们发布了 Kraken！

TheAnalyst

这是 Kraken 系列的第一个版本。它适合用于生产部署，并将维护直到下一个稳定版本发布。下一个版本 Luminous 将于2017年春季完成。

获取 11.2.0 "Kraken"

JEWEL 版本的主要变化

  • RADOS:
    • 新的 BlueStore 后端现在具有稳定的磁盘格式，并通过了我们的故障和压力测试。尽管该后端仍被标记为实验性，但我们鼓励用户在非生产集群和非关键数据集上试用它。
    • RADOS 现在对 纠删码 存储池的 覆盖写 提供实验性支持。由于磁盘格式和实现尚未最终确定，因此必须启用一个特殊的存储池选项才能测试此新功能。在集群上启用此选项将永久阻止该集群升级到未来的版本。
    • 我们现在默认使用 AsyncMessenger（ms 类型 = async）而不是旧的 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）。
    • 现在可以几乎立即检测到一些 OSD 故障，而之前必须等待心跳超时（默认为 20 秒）过期。  这可以防止 IO 在主机仍然启动但 ceph-osd 进程不再运行时被阻止很长时间。
    • 新增了一个 ceph-mgr 守护进程。目前默认情况下它与 monitors 位于同一位置，尚未被大量使用，但基本的基础设施已经就绪。
    • 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 现在支持一种新的区域类型，可用于通过 ElasticSearch 进行元数据索引。
    • RGW 现在支持 S3 多部分对象 copy-part API。
    • 现在可以对现有存储桶进行重新分片。请注意，存储桶重新分片目前要求对特定存储桶的所有 IO（尤其是写入）都处于静止状态。
    • 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 现在支持使用新的（实验性）覆盖写支持存储在 纠删码 RADOS 存储池中的镜像。必须使用新的 rbd CLI “–data-pool” 选项来创建镜像，以指定存储后端数据对象的 EC 存储池。尝试直接在 EC 存储池上创建镜像将不会成功，因为镜像的后端元数据仅支持在复制存储池上。
    • 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 现在修复回溯，并用发现的错误填充 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。
    • 已修复错误的“未能响应缓存压力”警告。

从 KRAKEN 候选版本 11.1.0 升级

  • 新的 BlueStore 后端在 11.1.0 之后进行了磁盘格式更改。使用 11.1.0 创建的任何 BlueStore OSD 都需要被销毁并重新创建。

从 JEWEL 升级

  • 所有集群必须首先升级到 Jewel 10.2.z，然后才能升级到 Kraken 11.2.z（或者最终升级到 Luminous 12.2.z）。
  • 在升级到 Kraken 之前，必须在 Jewel 集群上设置 sortbitwise 标志。最新的 Jewel (10.2.4+) 版本如果未设置此标志会发出健康警告，因此它可能已经设置。如果未设置，Kraken OSD 将拒绝启动并在其日志中打印错误消息。
  • 您可以按任意顺序升级 OSD、Monitors 和 MDS。RGW 守护进程应最后升级。
  • 升级时，新的 ceph-mgr 守护进程实例将自动与任何 monitors 一起创建。从 Jewel 到 Kraken 以及 Jewel 到 Luminous 的升级都是如此，但在 Luminous 之后的未来升级中可能不再如此。当然，如果您不希望它们与 ceph-mon 守护进程位于同一位置，您可以自由创建新的 ceph-mgr 守护进程实例并销毁自动创建的实例。

BLUESTORE

BlueStore 是一种新的后端，用于管理每个 OSD 直接存储在硬盘或 SSD 上的数据。与现有的 FileStore 实现不同，FileStore 利用 XFS 文件系统将对象存储为文件，而 BlueStore 直接管理底层块设备。它实现了自己的类似文件系统的磁盘结构，专门为 Ceph OSD 工作负载而设计。BlueStore 的主要功能包括：

  • 写入磁盘的所有数据都默认启用校验和，并在所有读取时进行校验和验证。
  • 内联压缩支持，可以通过存储池属性或客户端提示分别按存储池或按对象启用。
  • 高效的日志记录。与 FileStore 将 所有 数据写入其日志设备不同，BlueStore 仅记录元数据和（在某些情况下）小写入的日志，从而减少了其日志的大小和吞吐量要求。与 FileStore 一样，日志可以与其它数据位于同一设备上，也可以分配在较小的高性能设备上（例如，SSD 或 NVMe 设备）。默认情况下，BlueStore 日志仅为 512 MB。

BlueStore 磁盘格式预计将继续发展。但是，我们将在 OSD 中提供支持，以便在升级时迁移到新格式。

要启用 BlueStore，请将以下内容添加到 ceph.conf 中

enable experimental unrecoverable data corrupting features = bluestore

要创建 BlueStore OSD，请在创建 OSD 期间将 –bluestore 选项传递给 ceph-disk 或 ceph-deploy。

升级说明

  • OSD 现在避免在恢复正在进行时开始新的擦洗。要恢复到旧行为（不让恢复活动影响擦洗调度），您可以设置以下选项

    osd scrub during recovery = true

  • 用于构建 monmap 的 monitor 主机/地址列表现在可以从 DNS SRV 记录中获取。查询 DNS 时使用的服务名称在 “mon_dns_srv_name” 配置选项中定义，默认为 “ceph-mon”。

  • “osd class load list” 配置选项是允许 OSD 加载的对象类名称列表（或“*”表示所有类）。默认情况下，它包含所有现有的树内类，以实现向后兼容性。

  • “osd class default list” 配置选项是客户端可以仅具有“*”、“x”、“class-read”或“class-write”功能而调用的对象类名称列表（或“*”表示所有类）。默认情况下，它包含所有现有的树内类，以实现向后兼容性。调用未在“osd class default list”中列出的类需要一个命名该类的功能（例如“allow class foo”）。

  • “rgw rest getusage op compat” 配置选项允许您在 S3 GetUsage API 中转储（或不转储）用户统计信息的描述。此选项默认为 false。如果值为 true，则 GetUsage 的响应数据如下所示

    "stats": { "TotalBytes": 516, "TotalBytesRounded": 1024, "TotalEntries": 1 }

    如果值为 false，则 GetUsage 的响应看起来与以前一样

    { 516, 1024, 1 }

  • “osd out ...” 和 “osd in ...” 命令现在保留 OSD 权重。也就是说，在将 OSD 标记为 out 然后再标记为 in 之后，权重将与以前相同（而不是重置为 1.0）。以前，monitor 只有在自动标记 OSD out 然后再标记为 in 时才会保留权重，而在管理员明确操作时则不会。

  • “ceph osd perf” 命令将显示 “commit_latency(ms)” 和 “apply_latency(ms)”。以前，这两个列的名称是 “fs_commit_latency(ms)” 和 “fs_apply_latency(ms)”。我们删除了前缀 “fs_”，因为它们不是 filestore 特有的。

  • Monitor 不再允许默认删除存储池。必须将 mon_allow_pool_delete 设置为 true（默认为 false）才能允许删除存储池。这是防止意外删除存储池的额外保护措施。

  • 如果您已通过 mon keyvaluedb = rocksdb 选项手动指定了 monitor 用户 rocksdb，则需要手动将文件添加到 mon 数据目录以保留此选项

    echo rocksdb > /var/lib/ceph/mon/ceph-`hostname`/kv_backend

    新的 monitors 现在默认使用 rocksdb，但如果该文件不存在，则现有 monitors 将使用 leveldb。mon keyvaluedb 选项现在仅影响创建 monitor 时选择的后端。

  • “osd crush initial weight” 选项允许您为新添加的 OSD 指定 CRUSH 权重。以前，值 0（默认值）意味着我们应该使用 OSD 存储的大小来加权新的 OSD。现在，值 0 意味着它应该具有权重 0，负值（新默认值）意味着我们应该根据其大小自动加权 OSD。如果您的配置文件为此选项明确指定了值 0，则需要将其更改为负值（例如 -1）以保留当前行为。

  • 不再支持 osd crush location 配置选项。请更新您的 ceph.conf 以使用 crush location 选项。

  • debian development packages (lib*-dev) 不再包含静态库，因为 debian 打包策略不需要它。共享 (.so) 版本像以前一样打包。

  • debian development packages (lib*-dev) 不再包含 libtool pseudo-libraries (.la files)，因为根据 https://wiki.debian.org/ReleaseGoals/LAFileRemoval 和 https://www.debian.org/doc/manuals/maint-guide/advanced.en.html 的要求，它们是不需要的。

  • jerasure 和 shec 插件现在可以在运行时检测 SIMD 指令，不再需要为不同的处理器进行显式配置。以下插件现已弃用：jerasure_generic、jerasure_sse3、jerasure_sse4、jerasure_neon、shec_generic、shec_sse3、shec_sse4 和 shec_neon。如果您直接使用这些插件中的任何一个，您将在 mon 日志文件中看到警告。请切换到仅使用“jerasure”或“shec”。

  • librados omap get_keys 和 get_vals 操作包括一个起始键和返回的键数限制。OSD 现在对它将响应的键数和总字节数施加了一个可配置的限制，这意味着 librados 用户获得的键数可能少于他们请求的键数。这对于防止粗心的用户在单个操作中请求集群中不合理数量的数据是必要的。新限制通过 osd_max_omap_entries_per_request（默认为 131,072）和“osd_max_omap_bytes_per_request”（默认为 4MB）进行配置。

  • 恢复优先级的计算已更新。这可能会导致在集群升级期间恢复优先级不直观。在这种恢复情况下，旧版本的 OSD 将以与新版本不同的优先级范围运行。升级后，集群将以一致的值运行。
