在 Opscenter 5.0.1 中，“磁盘容量”和“磁盘统计信息”不可用。

Cassandra 数据和提交日志分别位于 NFS 挂载点：/net/cassandra_data 和 /net/cassandra_log。

我在 opscenterd.log 中发现了以下错误：

这看起来像是 OpsCenter 中的一个错误。我创建了一张票来修复它（内部票号是 OPSC-4080）。希望它会在下一个补丁版本（5.1.x）中得到修复。

对于那个很抱歉！

顺便说一句，我确定您以前看过此页面，但如果没有：http ://www.datastax.com/documentation/cassandra/2.1/cassandra/planning/architecturePlanningAntiPatterns_c.html?scroll=archPlanAntiPattern__shared-systems声明使用 NFS （或 NAS）是 C* 的反模式。
