I have a CentOS 6 server with NFS installed. In my /etc/exports file:

/shares/nfs 10.0.0.0/16(rw,sync,no_subtree_check,no_root_squash)

exportfs -a was done.

On my clients I have this in my /etc/fstab:

10.0.X.XX:/shares/nfs    /mnt/fs    nfs    hard,intr,retrans=2,rsize=32768,wsize=32768,noatime,timeo=600,nosuid   0 0

One client mounts the folder just fine, the other gives nobody:nobody user and permission to the files and therefore my applications can't use it? Why is this hapening? The UIDs are the same on both clients and the server and we don't use domain names, only IP addresses.

    First check the `/etc/idmap.conf` file on the server and clients and compare them. Especially the `Domain` at the beginning. If you have no luck, mount it as NFSv3 and add `vers=3,hard,...` to your `/etc/fstab` line. – Thomas Oct 07 '17 at 13:23
  • `[General] [Mapping] Nobody-User = nobody Nobody-Group = nobody [Translations] Method = nsswitch` This is all I have on my server. The exact same is on the clients.. Adding vers=3 didn't fix it, it just crashes the mount. – Bert Oct 07 '17 at 13:26
  • Hm, strange. Did you restart the `nfs` service already. Also try to `nfsidmap -c ` before restarting and remounting on the clients. – Thomas Oct 07 '17 at 13:42
  • Yes, restarted everything – Bert Oct 07 '17 at 16:04
