Disk

This role allows you to format extra disks and attach them to different mount points.

You can use it to move the data of different services to another disk.

Configuration

Inventory

Because the configuration for additional disks must be stored using the YAML syntax, you have to write it in a group_vars directory.

# inventory/group_vars/GROUP_NAME
disk_additional_disks:
- disk: /dev/sdb
  fstype: ext4
  mount_options: defaults
  mount: /data
  • disk is the device, you want to mount.
  • fstype allows you to choose the filesystem to use with the new disk.
  • mount_options allows you to specify custom mount options.
  • mount is the directory where the new disk should be mounted.

You can add:

  • disk_user sets owner of the mount directory (default: root)
  • disk_group sets group of the mount directory (default: root)
  • disk_package_use is the required package manager module to use (yum, apt, etc). The default 'auto' will use existing facts or try to autodetect it.

The following filesystems are currently supported:

How it works

It uses sfdisk to partition the disk with a single primary partition spanning the entire disk. The specified filesystem will then be created with mkfs. Finally the new partition will be mounted to the specified mount path.
