适用场景

ONTAP 9

问题描述

在 CIFS 共享中打开目录时,用户可能会间歇性地遇到 30 秒以上的延迟以及较高的其他操作延迟。与此相对应, Active IQ Unified Manager 中的利用率将显著提高,而工作负载不会相应增加:

EMS 还会出现零星的低内存错误:

 Wed Jul 28 02:59:09 -0500 [Node01: wafl_exempt06: wafl.memory.statusVeryLowMemory:alert]: WAFL is running very low on memory, with 5955MB remaining. 

如果正在使用 SnapMirror ,则可能还会出现如下错误:

 Wed Jul 28 00:11:27 -0500 [Node01: worker_thread_698: repl.out.of.memory:notice]: SnapMirror replication transfer encountered an out-of-memory error.
