Hi ,
The mount request was denied by the NFS server. Check that the export exists and that the client is permitted to mount it. An unknown error has occurred.
simple step , if think that you have fulfilled all the mandatory steps mentioned in many of the blogs and KB article.
Try : in ESXI add storage GUI Option
server : IP address only
folder :C:\Users\Administrator\Desktop\Share
<if you are using windows native NFS share , Using below command you can see the complete path and please give the same here c:\Users\Administrator\Desktop\Share >
Issue below command with your share name in windows host ,
C:\Users\Administrator>nfsshare share
Alias = Share
Path = C:\Users\Administrator\Desktop\Share
Supported security flavors are SYS
Encoding = ansi
UNMAPPED UNIX USER access allowed
ANONYMOUS access disallowed
Anonymous UID = -2
Anonymous GID = -2
HOST ACCESS :
ALL MACHINES read-write Root Access Allowed ansi
I hope below troubleshooting will also help if you have some different issue
Enable SSH on ESXI and putty log in to targeted ESXI and ping using vmkernel . I believe each esxi having vmkernel configured.
vmkping nfsserverip (vmkping command only support from esxi shell , it is not a part of vMA as of now .)
if it is pinging to destination Windows NFS IP . you have done . you can try the FQDN ping also here .
