新闻 Ceph v12.1.3 发布，分布式存储系统 下载

Ceph v12.1.3 发布了。这是 Luminous 最后一个候选版本，下次讲发布长期稳定版 Ceph Luminous（v12.2.0）。 自 Kraken（v11.2.z）和 Jewel（v10.2.z）以来，发生了重大变化，主要更新内容如下：

• 
  General:
  
  
  • 
    Ceph now has a simple, built-in web-based dashboard for monitoring cluster status.
    
• 
  RADOS:
  
  
  • 
    The new BlueStore backend for ceph-osd is now stable and the
    new default for newly created OSDs. BlueStore manages data
    stored by each OSD by directly managing the physical HDDs or
    SSDs without the use of an intervening file system like XFS.
    This provides greater performance and features. See
    Storage Devices and
    BlueStore Config Reference.
    
    
  • 
    BlueStore supports full data and metadata checksums of all
    data stored by Ceph.
    
    
  • 
    BlueStore supports inline compression using
    zlib, snappy, or LZ4. (Ceph also supports zstd for RGW compression but zstd is not recommended for
    BlueStore for performance reasons.)
    
    
  • 
    BlueStore:
    
    
  • 
    Erasure coded pools now have full support for overwrites,
    allowing them to be used with RBD and CephFS.
