Disable selinux.
In /etc/selinux/config, add make SELINUX=disabled and reboot.

Hi folks,
I've just started looking into ocfs2 as a means of allowing shared
storage on our iSCSI raid box for two of our servers. My intention is
to use linux-ha to provide highly available services (eg. samba) with
ocfs2 guaranteeing safe shared access to disk space. It seems
straightforward but I've run into a problem on one of the two servers.
Both servers are running RHEL 5 with the 2.6.18-53.1.4.el5 kernel.
They're identical in terms of hardware and iSCSI is working properly
on both. I've downloaded and installed the three ocfs2 RPMS (ocfs2,
ocfs2-tools and ocfs2console) successfully.
Following the instructions in the User's Guide I then type the following:
[EMAIL PROTECTED] OCFS2]# /etc/init.d/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
[EMAIL PROTECTED] OCFS2]# /etc/init.d/o2cb load
Loading module "configfs": OK
Mounting configfs filesystem at /sys/kernel/config: OK
Loading module "ocfs2_nodemanager": OK
Loading module "ocfs2_dlm": OK
Loading module "ocfs2_dlmfs": OK
Mounting ocfs2_dlmfs filesystem at /dlm: OK
All looking good but I run into problems on host2:
[EMAIL PROTECTED] OCFS2]# /etc/init.d/o2cb status
Module "configfs": Not loaded
Filesystem "configfs": Not mounted
Module "ocfs2_nodemanager": Not loaded

ocfs2_dlmfs is write-protected, mounting read-only
mount: cannot mount block device ocfs2_dlmfs read-only
Unable to mount ocfs2_dlmfs filesystem
Failed
This, I'm afraid, leaves me stumped. I'm not sure how best to proceed.
I've updated the RHEL5 kernel to 2.6.18-53.1.6.el5 and built rpms from
source for ocfs2 but to no avail. I get exactly the same problem on
the same host.
Does anyone have any ideas as to how I might proceed? Any help would
be greatly appreciated.
Cheers,
John
