问题描述

  • 要遇到此缺陷、用户必须通过ssh和公共密钥进行身份验证
  • ssh公共密钥身份验证会话(例如、自动化脚本)的频率越高、出现此缺陷的几率就越高
  • 此缺陷会将孤立索引节点留在节点/tmp/目录下、直到/tmp/达到100%使用率为止、并在数分钟内保持100%状态、直到数小时为止、最后再次降至~1-2%
  • 一旦/tmp/的使用率达到100%且ssh公共密钥身份验证仍在继续、而/tmp/的容量使用率仍为100%、此缺陷会将永久文件留在/mroot/etc/cluster-config/vserver/.vserver_*/config/auth.[0-9、a-z、A-Z ]+位置

生成的签名可能有所不同、例如:
1.使用串行控制台或虚拟SP或BMC的"system console"登录到ONTAP时、显示的错误如下所示:
SP MyCluster-01> system console
Type "exit" to log out of the console session.
Type Ctrl+D to return to the SP prompt.
SP-login: ad
pid 36994 (top), uid 0 inumber 20 on /tmp: filesystem full
pid 6889 (bash), uid 0 inumber 22 on /tmp: filesystem full

22出现类似于
Apply failed for Object: publickey_ui Method: baseline. Reason: Failed to generate fingerprint for the public key.

的错误3.使用公共密钥的SSH登录将故障恢复到密码身份验证、而如果用户在ONTAP中配置的ssh公共密钥旁边有密码、则密码身份验证仍可同时工作。
4.ONTAP EMS显示以下错误:
1/2/2025 15:05:23 node1 NOTICE sshd.auth.loginDenied: message="Failed password for user from 192.168.1.1 port 31337 ssh2 "
1/2/2025 15:05:11 node1 NOTICE sshd.auth.loginDenied: message="Failed keyboard-interactive / pam for user from 192.168.1.1 port 31337 ssh2 "

5。节点根卷(通常为"vol0")会长期显示已用的节点数不断增加。
