> File system error, check if path,permissions etc' from NDB
Looks like the error message tells you what you need to know... Compare
the user that data nodes run as with permissions for directory where
you're trying to create the DD files.
For example, if I were running ndbd's as 'jon', I would expect to run
into problems using files/directories in /usr/local/ which is owned by
'root'.
Hope this helps!
