If you used the default image for your self-hosted-engine, it will create the disk of the size you specified, (50GB) but only allocate the space it actually requires.

This means the remaining space on the allocated disk, is there, unused.   

Since it setup with LVM, you can use 'fdisk' to create a partition of that unused space.

Use pvcreate to add that partition to LVM,

Use vgextend to extend the appropriate volume group

Use lvextend to extend the appropriate logical volume, and file-system.

Subject: [ovirt-users] Expand the disk space of the hosting engine

Now my hosting engine /var directory is full, and the 15G free space is fully occupied. When creating the hosting engine, I use 100G, but actually only use 50G. What can I do to make /var bigger?
disk expansion
