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
disks_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
- device_name: /dev/sdf
fstype: ext4
mount_options: defaults
mount: /data
- disk: nfs-host:/nfs/export
fstype: nfs
mount_options: defaults,noatime
mount: /mnt/nfs
disk
is the device, you want to mount.part
is the first partition name. If not specified,1
will be appended to the disk name.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.user
sets owner of the mount directory (default:root
).group
sets group of the mount directory (default:root
).disable_periodic_fsck
deactivates the periodic ext3/4 filesystem check for the new disk.
You can add:
disks_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:
*) Note: To use these filesystems you have to define and install additional software packages. Please estimate the right package names for your operating system.
# inventory/group_vars/GROUP_NAME
disks_additional_packages:
- xfsprogs # package for mkfs.xfs on RedHat / Ubuntu
- btrfs-progs # package for mkfs.btrfs on CentOS / Debian
disks_additional_services:
- rpc.statd # start rpc.statd service for nfs
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.
