want to call the volume vgdata.
✓ vgcreate vgdata /dev/sdb1
Give the two commands that will allow you to see the volume group
✓ vgs - Shows a summary of available volume groups
vgdisplay - Shows a detailed list of volume groups and their properties
Show the command you would use to create a logical volume of half the
physical volume vgdata. Name the logical volume lvvol01

, 1 | P a g e | © copyright 2024/2025 | Grade A+
✓ XFS - can only be increased
EXT4 - can be increased and decreased
Btrfs - can be increased and decreased
If you are going to reduce an EXT4 file system, what state must it be in?
✓ You can only reduce the volume when it is offline
I want to add 250 megabytes to the file system /dev/vgdata/lvvol01. Show
the command
✓ lvresize -L +250M -r /dev/vgdata/lvvol01
I want to reduce the EXT4 file system by 250 megabytes. The LV is lvvol01, VG
is vgdata and the mount point is /files
✓ 1. umount /files
2. lvreduce -L -250M -r /dev/vgdata/lvvol01
I want to resize the LV to 75 percent of the Volume group. The LV is lvvol01,
VG is vgdata and the mount point is /files
✓ lvresize -r -l 75%VG /dev/vgdata/lvvol01
