i have drbd and ocfs with keepalive on ubuntu lucid, 2 loadbalancers, 2 mailservers with postfix and dovecot2 maildirs,clamav-milter,spamass-milter,sqlgrey, master-master mysql additional horde webmail on apache at both servers no problem so far, but for now i have only ca 100 mailboxes yet i wouldnt recommend nfs for mailstore if you want use gfs you might use better some redhat (clone) last time i tested it on ubuntu , i couldnt get it running as i expected it ( this may changed now...) i dont think there is some best solution depends on you hardware, finance resources, number of wanted mailboxes etc -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
