# openshift_expand_partition
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
* A machine with a disk that is not fully utilized
* cloud-utils-growpart rpm (either installed or avialable via yum or dnf)
* The partition you are expanding needs to be at the end of the partition list
## Role Variables
```
# The following variables are if you want to expand
# /dev/xvda3 that has a filesystem xfs
# 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
# What file system is on the partition
# Currently only xfs, and ext(2,3,4) are supported
# For ext2, ext3, or ext4 just use ext
oep_file_system: "xfs"
```
## Dependencies
growpart
## 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
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
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
```
