New twist on the old "Disk full"

[Hifly]

I´m having a problem with my 2.8ghz Quad-Core running 4GB of ram and 10.5.8.

I´m fairly unexperienced with OS X Server, so i hope some of you knows a trick or two to solve my problem...

This is the second time the system disk is full and the server crashes, shutting down services, rejecting mail to my users and denies access to both file sharing and VPN connections...

My setup is three 930GB disk in RAID with one "file storage" partition and one "system" partition. The "System" partition is 76GB but i only have 500mb of free space... Actual used space is only about 10-15GB...

The "File Storage" partition is OK, only the "System" partition that has problems...

Terminal shows: (sudo du -h -d 1 /)

Does anyone know what the problem could be? Can I delete the ".serverbackup" without risking that the entire mail-system goes byebye?

Thanks in advance!

[acme.mail.order]

What's in the directory and how did you create it?

As it's a backup it might contain a mountain of hardlinks - if you add them up separately you will count the same files many times.

/private also looks rather large, repeat the terminal command on that directory.

Might be your mail - it usually goes in /private/var/spool.

The server startet to deny to boot, so I had to contact Apple. Turns out that the mail DB is located on the "System" partition and with no quota for the users this filled up the partition. Copied the var/imap and var/spool/imap using ditto command to the bigger partition and booted up and set new destination for the mail db in Server Admin.

Now everything works and I am an Apple Care customer for some years. Nice to have when things get difficult.

But acme.mail.order, you were right. The mail was the problem.

Now, I am one happy man
