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.
[root@msdbdbadm01 ~]# mount -t nfs 192.168.63.34:/ExaBackup /backup mount.nfs: Connection timed out [root@msdbdbadm01 ~]#
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.
[root@msdbdbadm01 ~]# ping 192.168.63.34 PING 192.168.63.34 (192.168.63.34) 56(84) bytes of data. 64 bytes from 192.168.63.34: icmp_seq=1 ttl=63 time=0.186 ms 64 bytes from 192.168.63.34: icmp_seq=2 ttl=63 time=0.217 ms ^C --- 192.168.63.34 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1727ms rtt min/avg/max/mdev = 0.186/0.201/0.217/0.021 ms [root@msdbdbadm01 ~]#
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 [root@msdbdbadm01 ~]# mount -t cifs -o sec=ntlm,noperm,rsize=32768,wsize=32768,username=admin,password=123456aa,uid=root '\\192.168.63.34\ExaBackup' /backup
