------------------------------------------------------------
今天在做数据迁移，为了减少落地次数，就挂了个NFS目录来用，结果不巧遇到ORA-27054的错误，虽然知道这错误和NFS的挂载参数有关，也知道是Bug，但是还是小折腾了一会。
最开始的时候直接挂载，没有带任何参数，自然就出错了：
Export: Release 10.2.0.1.0 - 64bit Production on Sunday, 31 March, 2013 16:48:17
Copyright (c) 2003, 2005, Oracle. All rights reserved.
Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-31641: unable to create dump file "/dumpdir/ISTAML.20130331.dmp"
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options
Additional information: 6
于是按照要求，使用必须参数，重新挂载该目录：
[fxqdb1@root]# umount /dumpdir
[fxqdb1@root]# mount -o rw,bg,hard,intr,proto=tcp,vers=3,rsize=65535,wsize=65535,timeo=600 10.0.0.2:/dumpdir /dumpdir
[fxqdb1@root]# mount

10.0.0.2 /dumpdir /dumpdir nfs3 Mar 31 16:51 bg,hard,intr,rsize=65535,wsize=65535,sec=sys,rw以为会OK，结果还是报同样的错，最后没办法就把该NFS文件系统写入到系统的filesystems配置文件中，在重新挂载，问题搞定：
