Can anyone teach me here how to add a new disk and mount it to and
existing partition.

heres the scenario:

/var =50G already full

ill just add another 50 GB disk .which i also want to be part also of
/var i want my /var  to be 100G maintaining all my datas...

What you want to happen isn't that straightforward. Unless, you're already using some volume manager like LVM and a resizeable filesystem that will allow you to expand the partition automagically. The following HOWTOs should help you get started and decide which solution to use:

http://tldp.org/HOWTO/Hard-Disk-Upgrade/index.html
http://tldp.org/HOWTO/Software-RAID-HOWTO.html
http://tldp.org/HOWTO/LVM-HOWTO/index.html

You can either use RAID (linear or striping) to combine the capacity of
both disks, or use LVM which is the way to go if you plan to add
more drives in the future.

Hope this helps.


fdisk /dev/newdevice
partition it
mke2fs -j /dev/newdevice
modify /etc/fstab
something like /dev/newdevice  /mnt/newdrive  ext3  default 2 1
ln -s /mnt/newdrive /var/additionalfolder


This doesn't increase the size of the /var partition but instead only
creates another partition mounted inside some directory in /var.  "df -k
/var" would still give the original /var usage and capacity.

This won't scale even. Consider the scenario for example if the box is
a mail server that uses mbox with a near capacity /var/spool/mail.


Considering there will still be down time due to disk addtion. With that, i though you can just stop mail, then copy mbox dirs via /var/spool/mail to the new partition /var/newpartition/mail
then remove or move existing mbox rm /var/spool/mail, then link it to the new partition ln -s /var/newpartition/mail /var/spool/mail?
