<br>
Thanks again for your help. Still nothing in dmesg.<br>
<br>
I did get 2 trace files, which I'm sending you separately.<br>
<br>
Cheers,<br>

dmesg may be set up to ignore KERN_INFO messages. Let's
<br>
explicitly enable that. Also zip up the straces /tmp/mm.*.

OK, I've done a fresh install to test this. I'm using Sun VirtualBox
by the way.

Here's what I do:

mount.ocfs2: No such device while mounting /dev/sdb1 on /u01. Check
'dmesg' for more information on this error.
<br>

I can't see ANY errors in /var/log/messages, even with tracing turned
on!

Any ideas? As I said before, this works fine with the version of OCFS2
1.2 that comes on the DVD.
<br>
<br>
Cheers,

Enable some tracing. Do:
<br>
$ debugfs.ocfs2 -l ENTRY EXIT SUPER allow;
<br>
$ mount ...
<br>
$ debugfs.ocfs2 -l ENTRY EXIT deny SUPER off;
<br>
<br>
The logs will be in /var/log/messages.

get a "file not found" error, as if "/u01" doesn't exist (which it
does).

If I do the same thing but install OCFS2 1.2 from the DVD, this works
without problem.

Should 1.4 work as a local filesystem, or am I missing something?

<br>
Support for local mounts is in OCFS2 1.4. Does dmesg say anything?
