ceph monitor stat machine
2016-06-23 10:30:02 0 举报`ceph monitor stat machine`是一个Ceph命令，用于获取集群中每个OSD（对象存储设备）的状态信息。这个命令返回的信息包括每个OSD的ID、状态、权重、容量、数据使用量、可用空间、负载等信息。这些信息可以帮助管理员了解集群的健康状况，及时发现并解决可能的问题。例如，如果某个OSD的状态为down，那么可能需要检查该OSD的网络连接或者硬件状态。如果某个OSD的负载过高，可能需要调整其权重或者增加新的OSD来分担负载。总的来说，`ceph monitor stat machine`是一个非常有用的命令，对于维护和管理Ceph集群来说非常重要。
