Resizing Logical Volumes EXT4 using e2fsprogs 1.41.2-1
Mission:
Phase I
reduce LogVol14var by 1GB (to get space for other lv's)
increase LogVol14root by 224MB (less then 1 extent remaining)
Phase II not shown
increase LogVol14usr by 400MB (85%+ used)
reduce LogVol14home by 4GB (to make snapshot space)
VG-LV must be active but not mounted (LiveCD, rescue or second system)
