Okay, good to know that it's not a permissions problem.

This error message is from the old code.  I cannot help you unless you use
the latest code...

I don't have a clue what a Centos is.  If it's a type of Unix, then it
should work just fine.  I don't believe we do any dependence on Linux in
Perlbal anymore?  (Sendfile?  But that's not being called in this case.)

It's not creating directories, you say.  So perhaps there's something amiss
with that particular functionality.  What happens if you do this:

# perl -MFile::Path -e 'File::Path::mkpath("/var/mogdata/dev1/test/path", 0, 0755) or die "$!";'

Run that as root or whatever you run mogstored as.  Then, see if it created
the test path under the dev1 directory?  Otherwise, is it giving an error?

Perlbal uses that particular call to actually create directories.  If
that's failing, that would explain it.  If it succeeds, we'll have to try
something else... :)
