diskLib.dataCacheMaxSize = "0" 
diskLib.dataCacheMaxReadAheadSize = "0" 
diskLib.dataCacheMinReadAheadSize = "0" 
diskLib.dataCachePageSize = "4096" 
diskLib.maxUnsyncedWrites = "0" 


scsi1.present = "TRUE"

scsi1.virtualDev = "lsilogic"
scsi1.sharedBus = "VIRTUAL"

scsi1:1.present = "TRUE"
scsi1:1.deviceType = "disk"
scsi1:1.fileName = "F:\vmware\RAC\shared_disk\sdc.vmdk"
scsi1:1.mode = "independent-persistent"

Hi Listers,

I am trying to setup 2 nodes RAC (10G R2, Linux) in VMWARE (for self-educational purpose, of course).

After installing OCFS2 und mounting the "shared storage" in both nodes (Hostnames = node1 & node2) I have tried To perform a simple test (copying and/or editing a file from node1 and read the same file on node2).

I am getting the following errors:

[root_at_node2 ORCL]# dmesg | tail -15

Here is my configuration:
A) OS version
[root_at_node2 ORCL]# uname -a

Linux node2.example.com 2.6.9-22.EL #1 Mon Sep 19 18:20:28 EDT 2005 i686 i686 i386 GNU/Linux

[root_at_node1 ORCL]# cat < /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 2)

B) OCFS2 , downloaded from http://oss.oracle.com/projects/ocfs2/dist/files/RedHat/RHEL4/i386/

[root_at_node2 ORCL]# rpm -qa | grep ocfs2 ocfs2-2.6.9-22.EL-1.2.0-1 ocfs2console-1.2.0-1 ocfs2-tools-1.2.0-1

[root_at_node2 ORCL]# cat /proc/fs/ocfs2/version
OCFS2 1.2.0 Thu Feb 2 17:48:56 PST 2006 (build db06cd9cd891710e73c5d89a6b4d8812)

C) mountpoints
[root_at_node1 ORCL]# mount | grep ocfs

ocfs2_dlmfs on /dlm type ocfs2_dlmfs (rw) /dev/sdc5 on /u02/oradata/ORCL type ocfs2 (rw,_netdev,datavolume,heartbeat=local)

Any hints, suggestions, pointers are highly appreciated.
