This role is useful to expand a partition, and it's file system to fully utilize the disk it is on. It does this by first expanding the partition, and then expanding the file system on the partition.

Requirements

The partition you are expanding needs to be at the end of the partition list

# oep_drive
# Drive that has the partition we wish to expand.
oep_drive: "/dev/xvda"

# oep_partition
# Partition that we wish to expand.
oep_partition: 3

# oep_file_system

Example Playbook

With this playbook, the partition /dev/xvda3 will expand to fill the free space on /dev/xvda, and the file system will be expanded to fill the new partition space.

- hosts: mynodes
  become: no
  remote_user: root
  gather_facts: no
  roles:
    - role: openshift_expand_partition
      oep_drive: "/dev/xvda"
      oep_partition: 3
      oep_file_system: "xfs"

Full example

Create an inventory file:
```
[mynodes]
10.0.0.1
10.0.0.2
```
Create an ansible playbook, say expandvar.yaml: ```
- hosts: mynodes become: no remote_user: root gather_facts: no roles:
  - role: openshift_expand_partition oep_drive: "/dev/xvda" oep_partition: 3 oep_file_system: "xfs"

Run the playbook:

ansible-playbook -i inventory expandvar.yml
