Ocfs2 devel - Feb 2004 - important: ocfs2 version number bump

*** WARNING: None of this should be attempted on a production file system.

We've bumped up the version number in the ocfs2 module. This means however
that it won't mount ocfs1 filesystems. To be able to mount with ocfs2, you
MUST download, build and install the current SVN version of ocfs-tools and
do one of the following:

1) Format as a version 2 filesystem. Run mkfs.ocfs2 with the same options as
you used to use with 'mkfs.ocfs'. For example:

       mkfs.ocfs2 -b 4 -L ocfs2_test -m /ocfs2 /dev/sdb1


2) If you have an existing version 1 filesystem, then you can use the
tuneocfs '-c 2' option to bump up the version number. You will not be
able
to go back to version 1 after this.

	tuneocfs -c 2 /dev/sdb1

This option is currently undocumented as it is changing rapidly. Again, NONE
of this should be attempted on a production file system.

Okay maybe I'm doing something wrong.

But I just compiled up the latest code for ocfs2 and ocfs-tools.

I did the:

tuneocfs -c 2 /dev/sda1

When I try to mount my filesystem it now just hangs :(

Anyone else seeing this?  The previous revision of the code was working
for mounting and unmounting.

I don't see any messages in my /var/log/messages.

This is a Fedora Core 1 UniProcessor system with all the updates
applied.

I don't have all the info about the tracing.

I know that I need to change some values in /proc/...

I just need to go read the code a little bit more to figure it out :)

The latest version (revision 29) from the repository has fixed the issue
with the hang on the mount command.
