people : I am facing a issue , in my FreeBSD server box the /var
(85 % now) directory is going to full , no space left in this disk anymore .
But I have another disk in my box which is of 140 GB fresh disk , this I have to add so I gone through
the FreeBSD hand book of adding a new disk .
According to docs I sliced and partitioned the second disk ,
one doubt : here I created 10GB bsd partition in the second disk ,
I have to assign o assign this for /var (in my first disk /var is going to full)
Q1 ) so in /etc/fstab , the mount point what I have to specify ?
/var itself or I need to create a directory (mkdir /myspace )
and add it as the mount point in /etc/fstab ? like this
/dev/da1s1e /myspace ufs rw 2 2
OR
/dev/da1s1e /var ufs rw 2 2
which one is correct ?
and after this editing of /etc/fstab and restarting of the machine .
Q 2 ) my serverbox how it will continue to use the newly added space ? for this I have to do any thing
some one told me that I have to copy all the contents of the /var of first disk to this newly added space
is it right ?
how to do that
Q3 ) dd /dev/da0s1d /dev/da1s1/e right ? (to copy the content from /var (/dev/da0s1d) of the first disk to the newly added space for var on the second disk (/dev/da1s1e )
Q4 ) Is it needed to install all the applications which already installed in the /var of the first disk to the newly
added space on the second disk?
please give your tips and advice to achieve what I am trying to do. Many of you may have done this
before please help with your comments
Thanks in advance for all of you
Dhanesh

You will have to do something like the following:
- Mount the new partition to a temporary mount point (like /mnt) i.e.:
mount /dev/da1s1e /mnt
- Copy all the contents from /var to /mnt. Since /var is in use in a
running system, the results maybe less than optimal. I suggest you
switch to single user mode for doing this:
shutdown now
Use something like the following to transfer the files and permissions:
tar cfC - /var . | tar xpfC - /mnt
(thank you M.W. Lucas!)
Now, unmount /var and /mnt and mount your new var:
umount /var /mnt
mount -o rw /dev/da1s1e /var
Edit /etc/fstab and update it for the new disk:
/dev/da1s1e /var ufs rw 2 2
either exit to multi user mode or reboot. Of course, check that the
files were actually copied to their right places first!
