[Ocfs-users] OCFS2 and ASM Question

[Chris Taylor]

Thats kind of what I was looking for.  The Install Guides I'm looking at
didn't make it clear that they were separate.  Reading more closely, I
notice that the specific guide I'm going through only formats one partition
as OCFS2 and sets up the others as ASM.
 
As you can tell, I'm still learning the new 10g RAC architecture options and
appreciate the input.
 
Thanks,

Hi,
I can't understand why you want to use OCFS2 and ASM together in the same
partition.

For a Oracle rack instalation you MUST use OCFS2 or ASM for each partition.
you can't use the two together.

You you add your ocfs2 partition to asm you will corrupt that partition,
possibly loosing all your data. and you will need to format again the
partition.

Ok guys & gals here is the scenario:

1.) Host RHEL 4 U3 2.6.9-34.0.2.EL
2.) OCFS2 latest version
3.) Successfully formatted & mounted OCFS2 filesystems on 2 nodes
/dev/sdb1 /u02/oradata/usdev/voting
/dev/sdc1 /u02/oradata/usdev/data01
/dev/sdd1 /u02/oradata/usdev/data02
/dev/sde1 /u02/oradata/usdev/data03

4.) Downloaded & installed ASMLib 2.0 on both nodes
5.) Ran /etc/init.d/oracleasm configure
6.) Ran /etc/init.d/oracleasm createdisk vol1 /dev/sdc1
Error: asmtool: unable to clear device /dev/sdc1

7.) Shutdown node 2
8.) Ran /etc/init.d/oracleasm createdisk vol1 /dev/sdc1
Error: asmtool: unable to clear device /dev/sdc1

9.) Unmounted OCFS2 filesystems
10.) Ran /etc/init.d/oracleasm createdisk vol1 /dev/sdc1
Success
11.) Ran /etc/init.d/oracleasm createdisk vol2 /dev/sdd1 & /dev/sde1
Success
12.) Remount OCFS2 filesystems: mount -a -t ocfs2
Error:
ocfs2_hb_ctl: Bad magic number in superblock while reading uuid
mount.ocfs2: Error when attempting to run /sbin/ocfs2_hb_ctl: "Operation not
permitted"
ocfs2_hb_ctl: Bad magic number in superblock while reading uuid
mount.ocfs2: Error when attempting to run /sbin/ocfs2_hb_ctl: "Operation not
permitted"
ocfs2_hb_ctl: Bad magic number in superblock while reading uuid
mount.ocfs2: Error when attempting to run /sbin/ocfs2_hb_ctl: "Operation not
permitted"

13.) /etc/init.d/oracleasm listdisks
VOL1
VOL2
VOL3

SO...Are my OCFS2 partitions corrupted?  Or can I not mount them once
they're configured for ASM?
Is this the correct behavior, or am I missing something?

Thanks!!
