适用场景

  • ONTAP 9.13.1+,不带修复程序,适用于CONAP-115704
  • 正在使用SSH公共密钥身份验证、自动化脚本中的SSH会话可能非常频繁。
  • 节点根卷(vol0)的节点耗尽或永久增加。
  • 节点/tmp/目录容量耗尽。

问题描述

  • 与  /mroot/etc/cluster_config/vserver/.vserver_*/config/auth.[0-9,a-z,A-Z]+ 匹配的文件导致的较高的节点数。
  • CONTUP-115704 (原有ID 1595173)列出了不同的症状、其中一个症状是vol0 inode使用率持续增加。
  • 在以下示例中、节点MyCluster-02不受影响(最近已清理)、但节点MyCluster-01受影响严重、其Inode数超过1、200万:

MyCluster::*> node run -node * -command df -i vol0
2 entries were acted on.

Node: MyCluster-01
Filesystem               iused      ifree  %iused  Mounted on
/vol/vol0/            12330575    8920551     58%  /vol/vol0/

Node: MyCluster-02
Filesystem               iused      ifree  %iused  Mounted on
/vol/vol0/              294533   20956593      1%  /vol/vol0/

注意:通常两个节点都会受到影响、大小主要 取决于用于SSH访问的LIF在节点间的LIF分布。

  • 根卷中的异常高的Inode计数可能会导致不同子系统和进程出现不可预测的问题。
