Yes, that's probably the case. > So I ask. What newfs settings do you recommend for a 600GB partition > dedicated to maildirs? You will need a large number of inodes, so the fsck time will be very long if you use plain UFS. There are no newfs options that will be able to help it, I'm afraid. You should either use UFS with gjournal, or use ZFS. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
