ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

This will happen if you want to use a mounted NFS directory with no option in mounting NFS directory. The error that will come up is like this

RMAN-03009: failure of Control File and SPFILE Autobackup command on ORA_DISK_2
channel at 08/01/2006 16:43:49
ORA-19504: failed to create file “……”
ORA-27054: NFS file system where the file is created or resides is not mounted  with correct options Additional information: 2

The workaround that need to be done is too add this option while you remounting the NFS directory

rw,bg,intr,hard,timeo=600,wsize=32768,rsize=32768,nfserver=3,tcp

Hope this will fix your error
