Need to have the step, can this be done online or need to go offline (umount) the file systems.
To shink an ext3 filesystem, it'll have to be offline.
Start by identifying and terminating any applications with files open on /home using "fuser -vm /home/".
Once there are no open files, you can unmount the filesystem and use "fsadm resize /dev/mapper/vg_web-lv_home755G 150G" to shrink the filesystem.
