Ansible role: xnbd

Network block device

DEPRECATED

This functionality has been moved to kubernetes, so this ansible role is no longer maintained.

Requirements

Only tested on Debian buster.

Create 200GB image (cannot be sparse file):

ionice -c 3 dd if=/dev/zero of=/srv/nbd0.img bs=1M count=200K

Role Variables

• xnbd_role (default: server): a server exports a local block dev for a client to mount remotely

For clients:

• xnbd_hosts: inventory list of servers to connect to. Parsed by inventory_hostnames, so can include groups and set operators.

For servers:

• xnbd_address (default: localhost):
• xnbd_port (default: 8250): IP and port for server to listen on
• xnbd_img (default: /srv/nbd0.img): local block device (e.g., /dev/sda1) or image file to export

Playbooks

• main.yml: apply role
• uninstall.yml: remove. Run before removing config from inventory.

Dependencies

None.
