What is the version of the ocfs2-tools?
run mkfs.ocfs2 --version to get the tools version.
For 1.4.10, you need ocfs2-tools 1.6.3-2.

Hi this is a resend from a subscribed address sorry if I am causing any

hope some one can help me on this, I have been straggling to get this working
for few weeks now. My issue is as below
I am just trying to use ocfs2 as shared file system between 2
node HA cluster for a application that runs on these nodes
I have downloaded below packages
ocfs2-2.6.18-238.9.1.el5-1.4.9-1.el5.x86_64.r
and
ocfs2-2.6.18-308.1.1.el5-1.4.10-1.el5.x86_64
Installation goes with out any complains but when its time to
configure I get below errors
[root@ccbsn01 ~]# /etc/init.d/o2cb configure

This will configure the on-boot properties of the O2CB
driver.
The following questions will determine whether the driver is
loaded on
boot. The current values will be shown in brackets ('[]').
Hitting
ENTER without typing an answer will keep that
current value. Ctrl-C
will abort.

How can I fix this and get this working

[Ocfs2-users] HA-OCFS2?
Is it possible to create a highly-available OCFS2 cluster (i.e., A storage cluster that mitigates the single point of failure [SPoF] created by storing an OCFS2 volume on a single LUN)? The OCFS2 Project Page makes this claim... OCFS2 is a general-purpose shared-disk cluster file system for Linux capable of providing both high performance and high availability. ...but without backing-up the claim of high availability storage (at either the HDD- or the node-level). I've found a couple of articles hinting at using Linux Multipathing or DRBD but very little detailed information about either.

Re: [Ocfs2-users] HA-OCFS2?
cfs != storage You need to get a highly available storage that is concurrently accessible from multiple nodes. ocfs2 will allow multiple nodes to concurrently access the same storage. With posix semantics. If a node dies, the remaining nodes will pause to recover and then continue functioning. The dead node can then restart and rejoin the cluster.
