二：出错原因
mount没挂载对

三：解决办法
解决办法：重新挂载

1：先umount

[root@rac2 ~]# umount /home/oracle/arch

假如，报这个错误：umount: /home/oracle/arch: device is busy

用fuser -k 你的挂载点后，就可以umount掉了。

如：

[root@rac2 ~]# fuser -k /home/oracle/arch

/home/oracle/arch: 29915c 31456c 31457c

[root@rac2 ~]# umount /home/oracle/arch

2：以正确的方式重新挂载：

mount -t nfs -o rw,bg,hard,nointr,rsize=32768,wsize=32768,timeo=600,actimeo=0 rac1:/home/oracle/arch /home/oracle/arch
