3.在MOS上查找解决方案
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
| 1 2 |
root@cwgsdb1:~# umount /backup
root@cwgsdb1:~# mount -F nfs -o rw,bg,hard,rsize=32768,wsize=32768,vers=3 100.100.100.54:/impbackup /backup

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。
