Solution:

dnf install -y stratisd stratis-cli

systemctl enable --now stratisd

stratis pool create pool1 /dev/sdc

stratis filesystem create pool1 fs1

stratis filesystem list

Detailed Explanation:

stratisd is the daemon and stratis-cli provides the command-line interface.

A Stratis pool is created from a block device.

The Stratis file system is then created inside that pool.

RHEL 10 documents Stratis as an available volume-managing file-system layer. ( Red Hat Documentation )

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 )
