If I used no_root_squash in /etc/exports on server I can access directory without problem. /disk12 172.21.123.219(rw,sync,no_root_squash)
What can be the problem ?
You have kind of answered your own question here. If you need root access to the files from the client, you will need the 'no_root_squash'. All that option does is honour your clients root user over the NFS share (not great for security but I don't know your set up details).
Other than that you'd have to manage the users on both systems, to be the same name/uid/gid etc.. and do everything as a non-root user (better for security).
Take a look at this link[0] and hopefully that should clear it all up.
Thanks, Michael

Michael, In following situation if I access as root or non-root, I am facing same "Permission denied" error. So the problem is just not with root but all users.
client# ls -l /borneo4 ls: cannot access /borneo4/test-dir: Permission denied ?????????? ? ? ? ? ? test-dir client# su - eos client$ ls -lh /borneo4/ ls: cannot access /borneo4/test-dir: Permission denied total 0 ?????????? ? ? ? ? ? test-dir
And on server side I am ready change file permissions. By changing ownership of directory will solve this problem without using no_root_squash ?
Finally I solved this problem by just changing permission on server directory. server# chmod o+x /borneo4 Now my client can access without any problem. Thank You, Michael.
