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

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?
