How to reduce or shrink the size of logical Volume Manager Partitions

In my case I will shrink or reduce the /data size using lvreduce command. To reduce lvm size first umount the partition and run e2fsck & then resize2fs.

Steps to reduce the /data partition to 3GB

Step:1 Check the disk space using below command

Step:2Umount /data using below command : 

Step:3 Use e2fsck command to check the file system

Step:4 Resize the partition using below command

Enjoy !!!!
