#lsblk -pf (to check unused disks and partitions - let's say sda1 and sda2 are empty) #pvcreate /dev/sda1 /dev/sda2 #vgcreate -s 16M datastore /dev/sda1 /dev/sda2 #lvcreate -l 50 -n database datastore #mkfs.ext3 /dev/datastore/database #mkdir -p /mnt/database #lsblk -pf (to see the UUIDs) #echo 'UUID=XXX /mnt/data ext4 defaults 0 0' >> /etc/fstab (use real UUID of "database" volume from previous step instead of XXX) #systemctl daemon-reload #mount -a
