my hard disk is suddenly full ?????
 

I tried this:
[root@mail log]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda3 36G 36G 0 100% /
/dev/i2o/hda1 1.6T 867G 664G 57% /archive
/dev/hda1 99M 9.3M 85M 10% /boot
/dev/shm 251M 0 251M 0% /dev/shm
10.1.2.11:/Volumes/NEXSAN/mailbak
8.9T 4.1T 4.8T 46% /mailbak

what I can do to know what is the problem, it is my mail server

Maybe you could the size of /var/log, the problem could be out there.

I had a very similar problem..
Google this> Need help with full /tmp folder
It was a way to find and fix a full disk in Mandriva..
Goodluck

There are some apps out there that will show you a graphical representation of your filesystem which will then allow you to see what parts are the largest just by looking. Konqueror from KDE3 has a plugin for this called 'File Size View'(FSview). In konqueror/KDE3 you can get to it by View->View Mode->File Size View. It may help in spotting overly large files.

You can start there, and then look inside the bigger folder, and so on, until you find the big thing.

thanks guys for the help
I want to know where the directories are located in the hard drive
can I do that, for example can I check where my log file located in the hard disk (hda1 or hda2)
thanks again

I got this error msg when I tried to send an email

the size of the message you are trying to send exceeds a temporary size limit of the server. the message was not sent, try to reduce the message size then try again. the server responded: 4.4.5 Insufficient disk space, try again later.

If it is your mail server, where is the mail being delivered to? If it is somewhere in /var then you may need to adjust your system to mount a partition for the mail (or even for the entire /var directory - whatever you're happy with). Note: a little work needs to be done; you can't simply mount a new partition and expect things to work; you still need to preserve any directory structure and files for all the tools that use the directory.

Looking at that /var will be on the disk that ids full, which is where your logs /var/log are and prob the temp space used by your email.
