Command to apply a filesystem to a block device after its been created - Answer-
mkfs.TYPE BLOCKDEVICE

(i.e. for an xfs filesystem on /dev/vdb1, mkfs.xfs /dev/vdb1)

Command to apply an ext4 filesystem to the block device /dev/vdb1 - Answer-mkfs.ext4
/dev/vdb1

File to edit to persistently mount a filesystem after reboots - Answer-/etc/fstab

Entry format for mounting a filesystem persistently in /etc/fstab - Answer-UUID, mount
point, filesystem type, options, dump, fsck

What should the fsck be set to for xfs filesystems in /etc/fstab entries? - Answer-0

What should the fsck be set to for ext4 filesystems in /etc/fstab entries? - Answer-1 or 2
(1 for the root filesystem; 2 for other ext4 filesystems)

Command to scan block devices connected to a machine and retrieve filesystem UUIDs
- Answer-lsblk --fs

Command that must ALWAYS be run after making edits to /etc/fstab - Answer-systemctl
daemon-reload

, Command that should always be used after adding entries to /etc/fstab to ensure the

ends at 1257MB - Answer-parted /dev/vdb mkpart swap1 linux-swap 1001MB 1257MB

Two commands to create a primary partition on /dev/vdb to be used for a logical volume
that starts at 1MiB and ends at 769MiB

(Hint: the second command has to do with the partition being used to create a logical
volume. How do you set the partition type to Linux LVM?) - Answer-parted -s /dev/vdb
mkpart primary 1MiB 769MiB
parted -s /dev/vdb set 1 lvm on

Command to label/create the partition /dev/vdb1 as a pysical volume - Answer-pvcreate
/dev/vdb1

Command to create a volume group named vg01 with /dev/vdb1 and /dev/vdb2 physical
volumes - Answer-vgcreate vg01 /dev/vdb1 /dev/vdb2

Command to create a logical volume named lv01 of size 700M from the available
physical extents in the volume group vg01 - Answer-lvcreate -n lv01 -L 700M vg01

(-L sets the LV size in bytes; -l sets the LV size in extents)

Command to create an xfs filesystem on the logical volume lv01 in the volume group
