适用于

  • ONTAP 9
  • CIFS/SMB
  • FPolicy
  • Symphony

问题

  • 在多个文件操作期间,例如当 Fpolicy 存档解决方案必须调用每个文件时,将目录从 CIFS 共享复制到本地磁盘,文件会成功复制,直到某个文件返回"访问被拒绝"错误。如果重试该操作,它将成功,直到进一步的一些文件返回下一个错误。
  • vserver security trace  显示 Fpolicy 服务器拒绝访问

示例

vserver security trace trace-result show 

Vserver: svm1 
Node       Index Filter Details        Reason

--------------- ----- -------------------------- ------------------------------ 
node01         1    Security Style:  -
                                               Access is denied by the 
                         FPolicy server or due to 

                                         mandatory attribute of the 
                         FPolicy policy. 

 Protocol: cifs 
            Volume: - 
            Share: share1 
            Path: - 

      Win-User: Domain\user1 
            UNIX-User: root

  • ONTAP 中的 Fpolicy 日志可能包含 DENY 响应:
示例
 
[kern_fpolicy:nfo:6553] [enum clnt_stat FSMNbladeRespTask::shmSendRespToNblade(std::list<nbladeRespQueueElement_t>&, int, char *, CLIENT *)] reqId = XXXXXXXXXX respCode 2 : DENY 
 
  • 无法复制某些特定文件类型。
  • 数据包跟踪显示某些文件的访问被拒绝,此示例专门显示备用数据流 (ADS) 被拒绝。

  • 捕获 Fpolicy 外部服务器之间流量的网络跟踪将显示文件打开被 FPolicy 外部引擎拒绝:
示例
