As per the config, your node names are 'san' and 'mail'.
Are the names the same as the hostname?
Do on both nodes:
# for i in /config/cluster/san/node/*/local ; do LOCAL=`cat $i`; if [
$LOCAL -eq 1 ] ; then echo $i; fi; done;
You should see /config/cluster/san/node/mail/local on mail and
/config/cluster/san/node/san/local on san.
For more, refer to the user's guide, faq sand the mount/umount support
guide in the doc section on http://oss.oracle.com/projects/ocfs2.
