Hello,
You don't seem alone in having trouble with the installer finding candidate
disks. One additional thing I would check would be the following:
is your ASMLIB kernel module loaded?
/sbin/lsmod |grep asm
oracleasm 55176 1
Does your module version match your kernel version?
/sbin/modinfo oracleasm
filename:
/lib/modules/2.6.9-22.ELsmp/kernel/drivers/addon/oracleasm/oracleasm.ko
description: Kernel driver backing the Generic Linux ASM Library.
author: Joel Becker <joel.becker@xxxxxxxxxx>
version: 2.0.3
license: GPL
depends:
vermagic: 2.6.9-22.ELsmp SMP gcc-3.4
uname -r
2.6.9-22.ELsmp
Does oracleasm-discover find your devices?
sudo /usr/sbin/oracleasm-discover
Using ASMLib from /opt/oracle/extapi/64/asm/orcl/1/libasm.so

The permissions are correct, right? Your disks are owned grid:dba you are
running the oui with a user in those groups?
