CompTIA Linux+ XK0-006 (V8) Practice Question

During an overnight maintenance window you plan to shrink the ext4 file system located on /dev/mapper/vgdata-lvarchive. Before reducing the size of the underlying logical volume, you need to know exactly how many file-system blocks the volume can be reduced to so that you do not make it smaller than the data it contains. The file system is currently unmounted, and you want a command that only reports this minimum size without modifying anything. Which single command satisfies this requirement?

  • e2fsck -f /dev/mapper/vgdata-lvarchive

  • resize2fs -f /dev/mapper/vgdata-lvarchive

  • resize2fs -M /dev/mapper/vgdata-lvarchive

  • resize2fs -P /dev/mapper/vgdata-lvarchive
