分布式文件系统，Ceph v0.94.3 发布

jopen 9年前

Ceph是加州大学Santa Cruz分校的Sage Weil（DreamHost的联合创始人）专为博士论文设计的新一代自由软件分布式文件系统。自2007年毕业之后，Sage开始全职投入到Ceph开发之中，使其能适用于生产环境。Ceph的主要目标是设计成基于POSIX的没有单点故障的分布式文件系统，使数据能容错和无缝的复制。2010年3 月，Linus Torvalds将Ceph client合并到内核2.6.34中。

Ceph v0.94.3 发布，建议所有0.94.x的用户更新，主要更新内容如下：

The pg ls-by-{pool,primary,osd} commands and pg ls now take the argument recovering instead of recovery in order to include the recovering pgs in the listed pgs.
