Create a 1 GiB logical volume named lvbackup in volume group vgdata, format it with...

Solution:

lvcreate -L 1G -n lvbackup vgdata

mkfs.xfs /dev/vgdata/lvbackup

mkdir -p /backup

echo "/dev/vgdata/lvbackup /backup xfs defaults 0 0" > > /etc/fstab

mount -a

df -h /backup

Detailed Explanation:

lvcreate allocates a new LV from the existing VG.

mkfs.xfs creates the filesystem.

/etc/fstab makes the mount persistent across reboot.

mount -a tests the fstab entry immediately.

RHEL 10 storage documentation continues to use LVM and XFS as core administration topics. ( Red Hat Documentation )
