This is the common error DBA faces. Reason for getting this error may be bug or incorrect option while mounting the NFS mount point. Also this known bug.


Solution 
The solution which worked in this case was to set the below event which disables the mount point parameter checking:
sqlplus / as sysdba
alter system set events '10298 trace name context forever, level 32';

Or:

Set the following event in the init.ora
event="10298 trace name context forever, level 32"

Or 
setting event is workaround provided by oracle if this not help you then kindly mount the NFS mount point with correct option as below-
# mount -F nfs -o rw,bg,hard,rsize=32768,wsize=32768,vers=3,forcedirectio,nointr,proto=tcp,suid host:/folder1/to1 /folder2/to2
