====== lvm commands ======
===== Increase logical volume =====

Add 100 Gigabytes to LV
  lvextend -L +100G /dev/mapper/almalinux-lv_var

You also have to resize the partition table, e.g. for xfs filesystem

  fsadm resize /dev/mapper/almalinux-lv_var

Checking with ''df -h'' now should show increased size.

==== Tested on ====
  * AlmaLinux 9
===== Increasing disk of virtual machine =====

Restart VM then inside VM run (install ''cloud-utils-growpart'' and change the disk path accordingly)


  growpart /dev/sda 1
  pvresize /dev/sda1
  lvextend -l +100%FREE /dev/docker/docker

For ext4 FS
