Oracle Database 11.2 -- ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

Problem

While performing database export to an NFS share using Oracle Data Pump Export expdp utility, you get errors similar to below:

ORA-39001: invalid argument value 

ORA-39000: bad dump file specification 

ORA-31641: unable to create dump file "exp.dmp" 

ORA-27054: NFS file system where the file is created or resides is not mounted with correct options 

SVR4 Error: 2: No such file or directory 

Solution

The cause is probably incorrect mount options being used. Also, the options maybe correct but the order still invalid. 

Oracle documentation suggests the options used in the correct order like:

# mount -F nfs -o rw,bg,hard,rsize=32768,wsize=32768,vers=3,forcedirectio,nointr,proto=tcp,suid host:/folder1 /folder2

If the problem still persists, you might want to disable mount options checking by using the command:

sqlplus / as sysdba
alter system set events '10298 trace name context forever, level 32';

To enable mount option checking back:

alter system set events '10298 trace name context off';
