Mount.nfs: Connection timed out during Mount NFS Directory

I will explain Mount.nfs: Connection timed out during Mount NFS Directory error in this post.

 

Mount.nfs: Connection timed out

I have ExaBackup directory on QNAP storage, When i mount this directory to Exadata, I got the following error.

[[email protected] ~]# mount -t nfs 192.168.63.34:/ExaBackup /backup

mount.nfs: Connection timed out
[[email protected] ~]#

 

 

 

 

Normally I can mount this directory to Exadata with this command, but now it is not working and giving this error.

I have checked that the firewall is blocking our NFS server or not using Ping and telnet command.

 

[[email protected] ~]# ping 192.168.63.34

The Exadata server access the QNAP successfully, then I have understand that my error is related with the User permission, When i try to mount the directory with Admin user, I have seen that directory is mounted successfully as follows.

mount -t cifs -o sec=ntlm,noperm,rsize=32768,wsize=32768,username=admin,password=123456aa,uid=root '\\192.168.63.34\ExaBackup' /backup


[[email protected] ~]# mount -t cifs -o sec=ntlm,noperm,rsize=32768,wsize=32768,username=admin,password=123456aa,uid=root '\\192.168.63.34\ExaBackup' /backup
