问题描述

Permission denied/access denied 在客户端上挂载卷时看到的错误：

[root@client1 ~]# mount 10.1.2.3:/vol1 /mnt -v

mount.nfs: timeout set for Fri Mar 12 01:11:48 2021 mount.nfs: trying text-based options 'vers=4.1,addr=10.1.2.3,clientaddr=10.3.4.5' mount.nfs: mount(2): Operation not permitted mount.nfs: trying text-based options 'addr=10.1.2.3' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 10.1.2.3 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 10.1.2.3 prog 100005 vers 3 prot UDP port 635 mount.nfs: mount(2): Permission denied mount.nfs: Operation not permitted

[root@client1 ~]# mount 10.1.2.3:/vol1 /mnt mount.nfs: access denied by server while mounting 10.1.2.3:/vol1

适用于 Windows 的 NFS 客户端显示以下错误：

System error 53 has occurred. The network path was not found
