CentOS - Jun 2009 - 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

Yes, add a new disk to the system, then run commands such as:

pvcreate /dev/<whatever device it is>

vgextend VolGroup00 /dev/<whatever device it is>

lvextend (either -l +## to add extents or -L +## to add size)
/dev/VolGroup00/LogVol03

resize2fs /dev/VolGroup00/LogVol03
