can i move /var directory to new disk.

[sieven]

I would like to move the /var directory to the new disk.

I moved to vhost directory to new disk (/home).
Here I would like to move all -files, directories- of the /var to /etc/xvdb.

I hava 2 disks:
1. /dev/xvda : located /, root, bin, ..... all files and directories.
2. /dev/xvdb : Now is empty. Here I would like to move the /var directory.

is it possible?
