CentOS - Jan 2008 - Mounting /var directory to a new HardDisk

Hi,

I have a mailgw running Centos where trendmicro(IMSS) is installed. it
works perfectly. Now, the problem is it is running out of Harddisk.

pls see below  and pay attention to / file system (/dev/sda6), where
only 1.3 gb is available. these are not Logical volums (LVM)

[root at gateway 17141]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda6             9.7G  7.9G  1.3G  87% /
/dev/sda1              99M  9.2M   85M  10% /boot
/dev/sda5              15G   11G  3.5G  75% /opt
none                  627M     0  627M   0% /dev/shm

I checkd with du -h. then, I saw /var has 7.1 gb. So, Now I want to
know, If I plug a new harddisk and partion with fdisk and then format
that harddisk, will I able to mount /var directory to it ?

Your Ideas?

For sure you will be able to mount /var on your new disk....

but not before you boot single user and copy all the contents across manually
and then modify /etc/fstab to reflect the new location of /var.

In my experience it is nigh-on impossible to *move* /var when a system is
running.

Hint : next time use LVM *even* if you only have 1 physical disk to start with.
It makes this sort of situation an non-event.

Cheers.
