Please guide me to solve this issue.

If you had configured lvm while partitioning your hard disk, the issue
could've been sorted out in a simpler way.
Anyways, a crude way of solving this issue would be as below:
1. Run a 'du -sk /var/*' and make a note of directories which take up
more space.
2. Make a recursive copy of those directories (use 'cp -a' to be safe)
into a mouted partition with more space (for e.g. /usr).
3. Once you've confirmed that the files are safely copied (with
attributes, permissions intact), delete the original directories (the
ones in /var) that you copied. [You can directly use the 'mv' command
and move those directories, but I would be a little hesitant to do such
a thing on a live machine].
4. Create symbolic links from /var to the newly copied (or moved)
directories ('ln -s').
[Boot from a linux rescue CD-ROM and mount these partitions in
directories under /mnt or similar locations, to be more safe (to avoid
problems with lock files). Change directory path indicated above
appropriately.]
From now on, files that get created in some directories of /var will be
stored in /usr (or other partition where you linked the directories).
