Hi to all,

I am using 11.2.0.1.0 on RHEL 5.4

ASM is properly working on my machine. database is running from ASM. I want to configure additional oracleasm devices.

But command fails saying:

$ oracleasm createdisk ASMDISK08 /dev/xvd8
Writing disk header: done
Instantiating disk: failed
Clearing disk header: done

I am creating asm diskgroup on loopback devices

Here are the configured loopback devices.

[root@host1 ~]# ls -l /dev/loop[1-9]
brw-rw-rw- 1 oracle oinstall 7, 1 Oct 25 14:42 /dev/loop1
