I know things in concept , but I dare not to do in case I miss/ over
confident myself.

There is no such thing as urgent in public forum. If you are that urgent go find a consultant or pay someone, don't come here and ask for free help.

>> I do not have space in /usr

You should have allocated more space to /usr during initial install in the first place.
You don't even need to create a /boot partition at all, not to mention when you give it 1.9G, what a waste.

If I were you I'd reinstall from scratch, fighting with disk space problem is just unnecessary these days. Since I don't quite know your setup, but you can take a look at the layout as follow (a 40G hard disk):

/ - 120MB (usually 80mb is more than enough unless you don't follow hier standard and put stuffs all over your root)
/home - 6GB
/usr - 4GB (you are not supposed to load your local stuffs here, a 700MB is more than enough)
/usr/local - 5GB (you created 2.4GB but didn't use it. Why?)
/usr/X11R6 - 5GB
/var - 10GB
/www - 7GB

Could you not uninstall some of the programs you've got installed in /usr/bin and move (reinstall) them to /usr/local/bin? As freebsd points out, you've got a lot of free space in /usr/local so if you're not able to do a complete reinstall I'd try to move as much as possible from /usr to /usr/local

sorry do not which software can be uninstall so that it is large eough to re-install samba again.

the console is not in x-windows.

this is my 20 G server. I do not why it goes up as 94 % in "/".



would u please comment this ?

Well the calculation it's doing for % usage is:

(1 - (0.212 / 3.4)) x 100 = 93.8%

Which seems right. Though it's odd that total != used+free... 3.0 + 0.212 != 3.4

you can move /usr/lib to another partition or harddisk (to another harddisk will even speed up your whole system)

- boot into single user mode
- some distros need "mount -no remount,rw /" then
- fdisk, mke2fs the new partition (called hdxx from now)
- mkdir /usrlib
- mount /dev/hdxx /usrlib
- cd /usr ; mv lib /usrlib
- ln -s /usrlib/lib .
- umount /usrlib
- echo "/dev/hdxx /usrlib ext2 defaults 1 1 >>/etc/fstab"
- if you did the first mount command, you need to "umount /" now
- then reboot.

beware! a single mistake (by you or by me) and your system is in trouble.
