please help me as i am new to linux.

will give you info about logical volumes.
You could try deleting unwanted files etc from your lv's, followed byFailing that you need to add more physical storage or take some storage from another volume group.

For a summary, see

[root@oc0018158158 ~]# lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
lv_root vg_oc1443230061 -wi-ao---- 456.78g
lv_swap vg_oc1443230061 -wi-ao---- 8.00g

[root@oc0018158158 ~]# lvreduce -r
Please specify either size or extents but not both.
Run `lvreduce --help' for more information.

You are in bad situation, all space assigned to / .
You have to umount FS to reduce it and this is not possible for / .

Therefore you have to backup everything, because reducing is dangerous.

Then you will boot from rescue disk, not mounting local disk, vgscan, vgimport, vgchange -ay.
resize2fs to reduce / to desired size, lvreduce to same size +1m (to be sure).
Then you will have plenty free space to create whatever.

From other point of view, the new volume will be mounted under / , probably you can skip all
this headache and just mkdir ?

lvreduce has many variations in parameters - hence the ...
The -r parameter will automatically reduce the file system on the logical volume, safely.
Constructions such asworks for me.
(Change the 10% to whatever is required).

If you presently have one giant extent, this can take a very long time to run.
