Ceph depends upon Ceph Clients and Ceph OSD Daemons having knowledge of the cluster topology, which is inclusive of 5 maps collectively referred to as the “Cluster Map”: The Monitor Map: Contains the cluster fsid, the position, name address and port of each monitor. It also indicates the...
1. Client通过monitor获取集群当前的cluster map; 2. 在Client本地基于cluster map进行计算,得到对象最终存放的OSD节点信息; 3. 直接与OSD进行通信,完成对象的写入; 读过程: 读过程中对象位置查找与写过程类似,只是第三步由写操作改为读操作,将数据从集群中读到 ...
Ceph集群维护前面已经介绍了,由若干个monitor共同负责整个RADOS集群中所有OSD状态的发现与记录,并且共同形成cluster map的master版本,然后扩散至全体OSD以及client。OSD使用Cluster map进行数据的维护,而client使用Cluster map进行数据的寻址。monitor并不主动轮询各个OSD的当前状态。相反,OSD需要向monitor上报状态信息。常见的上...
CLUSTER_NAME.log是包含全局事件的主存储器集群日志文件。 缺省情况下,日志文件名为ceph.log。 只有 Ceph Monitor 节点包含主存储器集群日志。 每个Ceph OSD 和 Monitor 都有自己的日志文件,分别名为CLUSTER_NAME-osd.NUMBER.log和CLUSTER_NAME-mon.HOSTNAME.log。
