On SUSE Linux Enterprise Server 10 (SLES10), OCFS2 and Oracle ASMLib may fail to load/start at server boot despite being configured to do so. Once the server has finished booting, however, OCFS2 (o2cb/ocfs2) and  ASMLib (oracleasm) services can be loaded/started manually.

Failed o2cb/ocfs2 load/start symptoms include:
# lsmod | egrep 'ocfs2|configfs'

# service o2cb status
Module "configfs": Not loaded
Filesystem "configfs": Not mounted
Module "ocfs2_nodemanager": Not loaded
Module "ocfs2_dlm": Not loaded
Module "ocfs2_dlmfs": Not loaded
Filesystem "ocfs2_dlmfs": Not mounted

# mount -t ocfs2

Failed oracleasm load symptoms include:
# lsmod | grep oracleasm

# service oracleasm status
Checking if ASM is loaded:                                            dead

# dmesg | egrep -i 'oracleasm|asm'

# egrep -i 'oracleasm' /var/log/boot.msg
<notice>oracleasm start
Creating /dev/oracleasm mount point: done
<notice>'oracleasm start' exits with status 0

# ls -l /dev/oracleasm
total 0
