Create ASM on NFS

Postby kramer » Thu Jun 06, 2013 9:17 am

Hi

Actually i already posted my question bechind one article from oracle-base.
http://www.oracle-base.com/misc/comment ... age_id=907

But I think you may want me to post questions here.
So question :

I `m installing oracle grid 11.0.2.3 on oel 6. Two nodes.
I `m intending to create asm on nfs. Just like what you do in the article
http://www.oracle-base.com/articles/lin ... th-asm.php

Every step is the same. But When chage the discovery path to found the disk. Nothing found

Can give advice please?

Hi.

OK. I've answered on the comment, but let's continue the discussion here. It is far better to deal with technical stuff here. :)

Groups: You can use either DBA or oinstall. Probably better to follow the docs if that makes you happy. :)

Disk discovery: Disk will not show if their ownership or permissions are not correct. You should check that first.

Also, if you are repeating the installation after a failed installation, the disks will already be marked as ASM disks, so they will not be available. If this is the case, recreate the NFS files, to make sure they are not marked.

Cheers

Hi

Thanks you are right. It is because the permission. I changed to 777 as below

Code: Select all

[root@racnode1 ~]# chmod -R 777 /oracle_asm/
[root@racnode1 ~]# df -h /oracle_asm/
Filesystem            Size  Used Avail Use% Mounted on
192.168.100.42:/oracle01
                       30G  6.9G   23G  24% /oracle_asm


Then I can see the disks from OUI. Oh ... god.


But the doc do say it should be 660...
http://docs.oracle.com/cd/E11882_01/rac ... m#BCGICEDG

Am I misunderstanding the doc? Or the doc is wrong?

Hi.

1) Did you do the delete and create also.

I usually have to do both the overwrite of the file and that.

http://www.oracle-base.com/articles/rac ... #asm_disks

2) Also, do you see the disks when looking for "All Disks" (not just "Candidate Disks"). If they are visible from the "All Disks", but not from "Candidate Disks", you've not done your cleanup properly. If they are not visible from either, then is is usually a permissions thing. :)

Hi

I modified last my reply. You are right. The issue is because permission. BTW, you yourself run this forum and the oracle-base website?
If so, then it`s really impressive. It is a great work

Manay thanks:)Great website. BTW, do you also thinks it`s the oracle document having error?
http://docs.oracle.com/cd/E11882_01/rac ... m#BCGICEDG
Because there should be a lot people using the doc to install oracle. I cannt believe it`s wrong and No one talking about the error on web.

Hi.

What specifically?

If the permissions are correct for the group "dba", and the "oracle" user is part of that group, it should be fine. I don't hink the doc is wrong. It just makes the assumption your "dba" group is set up properly for your "oracle" user.
