Adapt to new Hetzner plans[1] for lower cost and better specs! 
CX11  -> CX22: Same price and better specs!
CX21  -> CX22: Cheaper price and same specs!
CX31  -> CX32: Cheaper price and better specs!
CPX11 -> CX22: Same price and similar spec! (for consistency)
CPX21 -> CX32: Cheaper price and better specs!
CPX41 -> CX42: Cheaper price and similar specs!

Some of the CX11 servers are not rescaled as they are on older, cheaper
grandfathered plans.

Growing (partitioned) Disks

Our VPS are provisioned with 20G as CX22 by default. When one is resized the disk size usually changes. To use the additional space, one needs to grow the partition and the filesystem.

Resizing partition

Grow the partition with a tool called growpart

growpart /dev/sdX <partnum>

So for most of our machines this is:

growpart /dev/sda 1

Resizing filesystem

This is straight forward

btrfs fi res max <mountpoint>

For most of our setups, being in the root homedir:

btrfs fi res max .
