I did too. When using ReiserFS /w Qmail, don't forget to apply "the patch". http://www.jedi.claranet.fr/qmail-link-sync.patch Details: http://www.jedi.claranet.fr/reisersmtp.html > I've heard good things about both jfs and xfs with vpopmail home and > qmail queue, but I haven't had time to play with them or benchmark them > under heavy load. The one thing that I might like with XFS over otehrs is that it is the only filesystem with documented hooks for using LVM snapshots Has anyone ever used snapshots with Ext3 or ReiserFS? Snapshots are great becasue it's the fastest way to backup your mail partition against user errors ("Help, I deleted my mailbox by mistake!") without adding stress/load to the mail server. -- Eric Ziegast
