使用“expdp ORA-27054”关键字查找，找到MOS文档：

ORA-27054: NFS File System Where the File is Created or Resides is Not Mounted With Correct Options (文档 ID 781349.1)

SYMPTOMS

You are transferring your database/installation to a NetApps NFS mount point.

The following error occurs on database startup:

ORA-01503: CREATE CONTROLFILE failed 
ORA-01565: error in identifying file '/nfs_d04/oasisxx/data/oasis_system.dbf' 
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

The current mount point is mounted as:

rw,bg,rsize=32768,wsize=32768,hard,vers=3,nointr,timeo=600,proto=tcp,suid 0 0

CAUSE

The correct mount point options are being used but they are not in the correct order per oracle docs on correctly mounting NFS mounts for oracle software.

The correct setting should be:

rw,bg,hard,rsize=32768,wsize=32768,vers=3,nointr,timeo=600,proto=tcp,suid

NOTE:  the location of the parameter 'hard'

NOTE:  As per  , the 'intr' & 'nointr' are deprecated in UEK kernels, as well as Oracle Linux 6. It is harmless to still include it, you will get a notice..

NFS: ignoring mount option: nointr.

SOLUTION

Mount the NFS mount point with the recommended options in the exact order specified in oracle documentation.

For example:
# mount -F nfs -o rw,bg,hard,rsize=32768,wsize=32768,vers=3,forcedirectio,nointr,proto=tcp,suid host:/folder1/to1 /folder2/to2

NOTE:  if settings revert back to original settings after remount, check auto-mounter options/settings.  For more info on auto-mounter, please contact the OS vendor.

4.重新挂载NFS文件

显然该问题是由NFS文件系统未正确挂载引起的，通过添加关键参数，重新挂载NFS系统，顺利解决Oracle执行expdp写入NFS文件系统提示ORA-39001 ORA-39000 ORA-31641 ORA-27054错误的问题。
