Oracle ASM Problem

[BS]

I have installed Centos and trying to install 10gR2. Wile adding the
disks to the ASM, I get the error as below

[***@whp-lindbmon ~]# /etc/init.d/oracleasm createdisk vol1 /dev/sda10

Marking disk "/dev/sda10" as an ASM disk: Error opening manager: No
such device or address


Any pointers?? The partition sda10 is there.


[***@whp-lindbmon ~]# fdisk -l /dev/sda

Any pointers?? The partition sda10 is there.

re-read the error message, the manager cannot be found.
did you configure and start asmlib?

Yes

Have you issued the command:

partprobe

or rebooted the machine after creating the devices?

Can you access them with a dd?

dd if=/dev/zero of=/dev/sda10 count=100 bs=4096

replace mycontinent with europe

Yes I did rebooted the machine after creating the partitions and I'm
able to use the partitions as well.

[***@whp-lindbmon software]# dd if=/dev/zero of=/dev/sda10 count=100

After the dd have you retried the create disk operation?

The error you reported is strange. I checked the asmlib sources.
It seems from an old asmlib version (1.x). Which version of ASMlib are
you using?

What happen if you try to create a disk group in your ASM without
exploiting ASMlib?

Regards

[BS]

It might be the wrong version that I had but it was not the version 1
of ASM. Here is how I fixed it.
