1. parted 分割硬碟，parted 模組文件，fs_type: ext4 可以立即將分割區格式化為 ext4，不用再使用 filesystem 模組格式化分割區。

   ceuser@deyu:~/ansible_pb$ ansible-doc parted| grep ^EX -A36
   EXAMPLES:
   
   - name: Create a new ext4 primary partition
     community.general.parted:
       device: /dev/sdb
       number: 1
       state: present
       fs_type: ext4
   
   - name: Remove partition number 1
     community.general.parted:
       device: /dev/sdb
       number: 1
       state: absent
   
   - name: Create a new primary partition with a size of 1GiB
     community.general.parted:
       device: /dev/sdb
       number: 1
       state: present
       part_end: 1GiB
   
   - name: Create a new primary partition for LVM
     community.general.parted:
       device: /dev/sdb
       number: 2
       flags: [ lvm ]
       state: present
       part_start: 1GiB
   
   - name: Create a new primary partition with a size of 1GiB at disk's end
     community.general.parted:
       device: /dev/sdb
       number: 3
       state: present
       fs_type: ext3
       part_start: -1GiB
   

2. filesystem 檔案系統管理，filesystem 模組文件。

   ceuser@deyu:~/ansible_pb$ ansible-doc filesystem | grep ^EX -A30
   EXAMPLES:
   
   - name: Create a ext2 filesystem on /dev/sdb1
     community.general.filesystem:
       fstype: ext2
       dev: /dev/sdb1
   
   - name: Create a ext4 filesystem on /dev/sdb1 and check disk blocks
     community.general.filesystem:
       fstype: ext4
       dev: /dev/sdb1
       opts: -cc
   
   - name: Blank filesystem signature on /dev/sdb1
     community.general.filesystem:
       dev: /dev/sdb1
       state: absent
   
   - name: Create a filesystem on top of a regular file
     community.general.filesystem:
       dev: /path/to/disk.img
       fstype: vfat
   

3. 檔案系統掛載管理，mount 模組將掛載要求寫入開機自動掛載表 /etc/fstab 中，其中 state: mounted 指定寫入 /etc/fstab 後立即掛載。

   ceuser@deyu:~/ansible_pb$ ansible-doc mount | grep ^EX -A86
   EXAMPLES:
   
   # Before 2.3, option 'name' was used instead of 'path'
   - name: Mount DVD read-only
     ansible.posix.mount:
       path: /mnt/dvd
       src: /dev/sr0
       fstype: iso9660
       opts: ro,noauto
       state: present
   
   - name: Mount up device by label
     ansible.posix.mount:
       path: /srv/disk
       src: LABEL=SOME_LABEL
       fstype: ext4
       state: present
   
   - name: Mount up device by UUID
     ansible.posix.mount:
       path: /home
       src: UUID=b3e48f45-f933-4c8e-a700-22a159ec9077
       fstype: xfs
       opts: noatime
       state: present
   
   - name: Unmount a mounted volume
     ansible.posix.mount:
       path: /tmp/mnt-pnt
       state: unmounted
   
   - name: Remount a mounted volume
     ansible.posix.mount:
       path: /tmp/mnt-pnt
       state: remounted
   
   # The following will not save changes to fstab, and only be temporary until
   # a reboot, or until calling "state: unmounted" followed by "state: mounted"
   # on the same "path"
   - name: Remount a mounted volume and append exec to the existing options
     ansible.posix.mount:
       path: /tmp
       state: remounted
       opts: exec
   
   - name: Mount and bind a volume
     ansible.posix.mount:
       path: /system/new_volume/boot
       src: /boot
       opts: bind
       state: mounted
       fstype: none
   
   - name: Mount an NFS volume
     ansible.posix.mount:
       src: 192.168.1.100:/nfs/ssd/shared_data
       path: /mnt/shared_data
       opts: rw,sync,hard
       state: mounted
       fstype: nfs
   
   - name: Mount NFS volumes with noauto according to boot option
     ansible.posix.mount:
       src: 192.168.1.100:/nfs/ssd/shared_data
       path: /mnt/shared_data
       opts: rw,sync,hard
       boot: false
       state: mounted
       fstype: nfs
   
   - name: Mount ephemeral SMB volume
     ansible.posix.mount:
       src: //192.168.1.200/share
       path: /mnt/smb_share
       opts: "rw,vers=3,file_mode=0600,dir_mode=0700,dom={{ ad_domain }},username={{ ad_username }},password={{ ad_password }}"
       fstype: cifs
       state: ephemeral
