问题描述

重新启动节点后，某些 UNIX 客户端无法访问 CIFS 共享文件夹
问题并不会影响所有客户端
列出共享文件夹的内容被拒绝，当尝试访问列出的文件夹时 - 在这种情况下，看到的文件夹"Shared"，权限被拒绝

root@client1~]# df -hT |grep -i cifs
 //system.domain.com/Apps/Reports/Shared/NRFB  cifs    175G  35G  141G  20% /reports/NRFB
 //system.domain.com/Apps/Reports/Shared/ALL  cifs    175G  35G  141G  20% /reports/ALL
 //system.domain.com/Apps/Reports/Shared/RFB  cifs    175G  35G  141G  20% /reports/RFB
 [root@client1~]# ls /reports/NRFB
 Shared
 [root@client1~]# ls /reports/ALL
 Shared
 [root@client1~]# ls /reports/RFB
 Shared
 [root@apptup01df Shared]# df -hT |grep -i cifs
 //system.domain.com/Apps/Reports/Shared/RFB  cifs    175G  35G  141G  20% /reports/RFB
 //system.domain.com/Apps/Reports/Shared/NRFB  cifs    175G  35G  141G  20% /reports/NRFB
 //system.domain.com/Apps/Reports/Shared/ALL  cifs    175G  35G  141G  20% /reports/ALL
 [root@apptup01df Shared]# ls /reports/RFB/Shared/
 ls: reading directory '/reports/RFB/Shared/': Permission denied

客户端正在列出共享的更高文件夹：

[root@client1 Shared]# cd ~
 [root@client1 ~]# ls -lrth /reports/RFB
 total 0
 drwxr-xr-x. 2 user01 group01 0 Nov 10  2023 Shared
 [root@client1 ~]# ls -lrth /reports/NRFB
 total 0
 drwxr-xr-x. 2 user01 group01 0 Nov 10  2023 Shared
 [root@client1 ~]# ls -lrth /reports/ALL
 total 0
 drwxr-xr-x. 2 user01 group01 0 Nov 10  2023 Shared
 [root@client1 ~]#

再次卸载和装载共享时，没有问题 - 在这种情况下，正确的文件已列出并可访问：

[root@client1 ~]# df -hT |grep -i cifs
 //system.domain.com/Apps/Reports/Shared/RFB  cifs    175G  35G  141G  20% /reports/RFB
 //system.domain.com/Apps/Reports/Shared/NRFB  cifs    175G  35G  141G  20% /reports/NRFB
 //system.domain.com/Apps/Reports/Shared/ALL  cifs    175G  35G  141G  20% /reports/ALL
