Disk

This role lets you format extra disks and connect them to different locations.

You can use it to move data from various services to another disk.

Configuration

Inventory

You need to store the configuration for additional disks using YAML syntax in a group_vars directory.

# inventory/group_vars/GROUP_NAME
disk_additional_disks:
 - disk: /dev/sdb
   fstype: ext4
   mount_options: defaults
   mount: /data
   user: www-data
   group: www-data
   disable_periodic_fsck: false
 - disk: /dev/nvme0n1
   part: /dev/nvme0n1p1
   fstype: xfs
   mount_options: defaults,noatime
   mount: /data2

• disk is the device you want to mount.
• part is the name of the first partition. If you don't specify it, 1 is added to the disk name.
• fstype lets you choose the type of filesystem for the new disk.
• mount_options allows you to set custom options for mounting.
• mount is the directory where the new disk will be attached.
• user sets who owns the mount directory (default is root).
• group sets the group for the mount directory (default is root).
• disable_periodic_fsck turns off the regular filesystem check for the new disk.

You can also add:

• disk_package_use specifies the package manager to use (yum, apt, etc.). The default 'auto' will automatically detect it.

Supported Filesystems:

• ext2
• ext3
• ext4
• xfs*
• btrfs*

*) Note: To use these filesystems, you need to install additional software packages. Make sure to find the correct package names for your operating system.

# inventory/group_vars/GROUP_NAME
additional_fs_utils:
  - xfsprogs     # package for mkfs.xfs on RedHat / Ubuntu
  - btrfs-progs  # package for mkfs.btrfs on CentOS / Debian

How it works

The process uses sfdisk to create a primary partition that covers the whole disk. Then, it creates the specified filesystem using mkfs. Finally, it mounts the new partition to the designated path.
