[CentOS] Partitionning for future.

Hi all,

I have a disk of 146Gb in a machine intended to have mainly mysql database, apache and some web data.  I didn't use LVM for / and /boot during the installtion

Could I extend  easily in the future the /var partition  when I add another disk?

Filesystem            Size  Used Avail Use% Mounted on /dev/cciss/c0d0p6      23G  432M   22G   2% / /dev/mapper/VolGroup00-LogVol00                       5.0G  139M  4.7G   3% /home /dev/mapper/VolGroup00-LogVol03                        98G  275M   93G   1% /var /dev/mapper/VolGroup00-LogVol02                       5.0G  2.9G  1.9G  61% /usr /dev/cciss/c0d0p1      99M   19M   75M  20% /boot tmpfs                 470M     0  470M   0% /dev/shm

I would like to have your comments before I continue installin MySQL and others.

Thanks Yaovi
