This is my /etc/exports in AIX NFS server(

/app_src/g2s/workspace -vers=3,access=[],rw=[],root=[]

Of course, I run exportfs -av after renewing

I tried this command on a Ubuntu NFS client(

sudo mount -t nfs -o vers=3 ./import

However it returns

mount.nfs: access denied by server while mounting

How can I solve it ?

    Does your Ubuntu server have a different interface that it's using to get to the AIX NFS server?

  • it seems permission problem , check the owner and group of share and permission on that , also check by disabling firewall and SE-Linux on the server

  • @Ijaz Khan What permission should I check ?, I think the permission is allowed by /etc/exports file.

  • @Julie Pelletier Where can I check the log in AIX?

You need reverse lookup in DNS to allow NFS to mount. I have the same issue:

[root@usmd1lnx095 init.d]# host
Host not found: 3(NXDOMAIN)
[root@usmd1lnx095 init.d]#

I'm trying to get my DNS fixed. I have an AIX server that mounts a filesystem to MANY servers. I just built this one and it can't mount. It's DNS, fer sher.


Typically you don't include IP addresses inside [..] and just list them as normal:

/app_src/g2s/workspace -vers=3,access=,rw=,root=

You should be able to verify the export is correct with

showmount -e
  • showmount -e returns export list for psrsmsapp01: /app_src/g2s/workspace but it still deny access.

We had the same problems, I fixed this problem after add ip and hostname in /etc/hosts from NFS AIX Server.
