The breakdown for storage on Docker agents is:
Currently "???" is 12GB of Docker images and 2GB (worst-case)/executor for Docker containers. This is currently stored on / with the OS. The free space will vary based on instance-type. The needed space for running Docker containers will vary with agent executors.

Change 459850 had a related patch set uploaded (by Dduvall; owner: Dduvall):
[operations/puppet@production] Parameterize profile::labs::lvm::srv volume size
Change 459850 abandoned by Dduvall:
Parameterize profile::labs::lvm::srv volume size
Reason:
An additional logical volume can be achieved as long as it's created first. See https://gerrit.wikimedia.org/r/c/operations/puppet/ /459875
Solution adopted in T203841: Provide dedicated storage space to Docker for images/containers did not require free LVM extents.
