Dear all,

I follow this tutorial to install Oracle Cluster 11GR2:

I created share file system:


[root@dbhost1 ~]# mkdir /shared_1

[root@dbhost1 ~]# mkdir /shared_2

[root@dbhost1 ~]# mkdir /shared_3

[root@dbhost1 ~]# chown oracle:dba /shared_1

[root@dbhost1 ~]# chown oracle:dba /shared_2

[root@dbhost1 ~]# chown oracle:dba /shared_3

[root@dbhost1 ~]# chmod g+w /shared_1

[root@dbhost1 ~]# chmod g+w /shared_2

[root@dbhost1 ~]# chmod g+w /shared_3
[root@dbhost1 ~]# more /etc/exports

/shared_1 *(rw,sync,no_wdelay,insecure_locks,no_root_squash)

/shared_2 *(rw,sync,no_wdelay,insecure_locks,no_root_squash)

/shared_3 *(rw,sync,no_wdelay,insecure_locks,no_root_squash)

[root@dbhost1 ~]# tail -3 /etc/fstab

nfshost:/shared_1 /u01 nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0
nfshost:/shared_2 /u02 nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0
nfshost:/shared_3 /u03 nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0
[root@dbhost1 ~]# mount /u01
mount.nfs: mount options: "bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0,addr="

But when I checked there is no /u01:


#df -h
Filesystem Size Used Avail Use% Mounted on
50G 8.4G 39G 19% /
tmpfs 1.9G 80K 1.9G 1% /dev/shm
/dev/sda1 477M 64M 384M 15% /boot
45G 9.0G 34G 22% /home
/dev/sr0 3.6G 3.6G 0 100% /media/OL6.6 x86_64 Disc 1 20141018

Please help me. Thanks very much.

Welcome to the forum. Please read our OraFAQ Forum Guide and How to use [code] tags and make your code easier to read

Generally speaking, if you have a problem with an article like that, you should ask the author of the article.
However, in this case I think it is obvious: you have not created the /u0% mount points.

Note that this question is nothing to do with Oracle, it is to do with NFS. You need to ask it on a Unix forum, not here.

As John said, you didn't create the directories for the mount points. You did this:

[root@dbhost1 ~]# mkdir /shared_1

[root@dbhost1 ~]# mkdir /shared_2

[root@dbhost1 ~]# mkdir /shared_3

But you should have done this:

[root@dbhost1 ~]# mkdir /u01

[root@dbhost1 ~]# mkdir /u02

[root@dbhost1 ~]# mkdir /u03

And of course, change owner, permissions, all that...

Also...which NFS vendor are you using? You might want to consult their documentation to ensure those mount options are correct for their product running Oracle databases.

This question bears no real connection with Oracle database.
Please find a more appropriate forum.
