Ben,

There is no clear line in my mixture. Therefore the AUSDRUCK 'mixture'. I begun about two years ago (for backup reasons) to set defaults that way, that every new mailbox will be mdir. Then I changed the biggest mailboxes from mbox to mdir. It was really a sort of biggest boxes first (in terms of GB). There were also InBox- and sent-folders I have changed. We have no Junk folders.

As I said, no clear line but a mixture or a mess ;-)

Marcel,

When you say a mixture of mbox and mdir what do you mean exactly?  Which boxes are in what format?  I have converted the Junk folders to mbox and am considering changing all other boxes except INBOX and Sent.

Thanks for your input,

Ben

Hi Ben

We are running CGP 5.1.10 on Xserve G4 1x1GHz and Mac OS X Server 10.4.8.
We use 'Apple Software RAID' to mirror two disks (the other two internal disks are for backup besides nightly external backup). CGP and BIND are running on this box. 200 Accounts, 90 GB Data, 250k Files, a mix of mdir and mbox. Heavy daily load, but no problem with performance.
-> No crashes at all, since many years!

Have you considered Xsan with your Xserve RAID (which uses Cluster File System instead of HFS+)?

I am currently experiencing a fatal error on my CGP Server running on an
xserve G5 with Mac OS 10.4.10.  The problem is an HFS bug in 10.4 that occurs
when using many small files.  This causes the server to kernel panic and
restart.  We are running CGP 5.1.11 with mdir mailboxes.  We are not
particularly tied to the mdir format, but we do like it for backup purposes.

How many files are you talking? We use a mix of mdir and mbox for folders--
generally using mdir for Inbox, Sent Items and other volatile boxes and mbox
for archive folders-- and we're backing up in the neighborhood of 400,000
files (90GB total) without difficulty. Server is running 10.4.9 Universal on
a dual-processor G5 Xserve, data is stored on a Xserve RAID formatted
HFS+Journaled. Everything has been rock-solid.
