The following example demonstrates the Linux commands that are used in order to create the logical volumes and file systems for the application/logs disk and the data disk.
It is assumed that the operating system disk (sda) was already properly configured, and the the application/logs disk is named sdb and the data disk is named sdc.
# This is an example - make sure to adjust it to your system! # If LVM is not available on you system you may use 'dnf install lvm2' before executing the commands. # Creating the app/logs volume group as vg_app along with its logical volumes and file systems pvcreate -ff /dev/sdb vgcreate vg_app /dev/sdb lvcreate -L 1G -n lv_shared vg_app mkfs.xfs -f /dev/vg_app/lv_shared echo "/dev/vg_app/lv_shared /shared xfs defaults 0 0" >> /etc/fstab mkdir -p /shared mount /shared lvcreate -L 30G -n lv_app vg_app mkfs.xfs -f /dev/vg_app/lv_app echo "/dev/vg_app/lv_app /app xfs defaults 0 0" >> /etc/fstab mkdir -p /app mount /app lvcreate -L 8G -n lv_app_tmp vg_app mkfs.xfs -f /dev/vg_app/lv_app_tmp echo "/dev/vg_app/lv_app_tmp /app/tmp xfs defaults 0 0" >> /etc/fstab mkdir -p /app/tmp mount /app/tmp lvcreate -L 30G -n lv_installs vg_app mkfs.xfs -f /dev/vg_app/lv_installs echo "/dev/vg_app/lv_installs /installs xfs defaults 0 0" >> /etc/fstab mkdir -p /installs mount /installs lvcreate -L 15G -n lv_logs vg_app mkfs.xfs -f /dev/vg_app/lv_logs echo "/dev/vg_app/lv_logs /logs xfs defaults 0 0" >> /etc/fstab mkdir -p /logs mount /logs # Creating the data volume group as vg_data along with its logical volume and file system pvcreate -ff /dev/sdc vgcreate vg_data /dev/sdc lvcreate -l 100%FREE -n lv_data vg_data mkfs.xfs -f /dev/vg_data/lv_data echo "/dev/vg_data/lv_data /data xfs defaults 0 0" >> /etc/fstab mkdir -p /data mount /data
