Lumen® Edge Bare Metal support: Drive layout

Learn how storage is delivered to Edge Bare Metal servers. At time of deployment, only the boot drive is formatted and configured for the installed operating system. The other drives are available for your use as you see fit.

 

The boot drive for Linux operating systems is configured as follows:
 

  1. /boot/efi1 a "fat32" partition used for booting the operating system. In our deployments, this is typically 536MiB.
  2. The rest of the disk is configured to use LVM2. This allows post deployment configuration, including adding storage from other available local disks, as needed.
  3. A relatively small "os-root" mounted at / to provide the initial area for the installed operating system.
  4. Leaving just under 180GiB for post-deployment user configuration.

[3] provides strong recommendations about specific ways to carve up, and what options should be applied to specific directories. By providing the system configured with LVM, you can implement the requirements of this standard.

 

This allows freedom to use any filesystem supported by the operating system you selected. For Linux systems, that is usually some combination of ext{2,3,4}, xfs, btrfs, or zfs. Lumen places no limitations on your filesystem choice.

 

The precise amount of disk space in any given initial partition is subject to change.
