mount 模組

1. 修改 partedfs.yml 為 partedfsmnt.yml，新增目錄 /newpart，在開機掛載表中新增 /dev/vdb1 掛載在 /newpart，且立即掛載。

   [deyu1@kvm19 10827000]$ cat partedfsmnt.yml
   ---
   - hosts: balancers
     tasks:
     - name: Create a new primary partition with a size of 2GiB
       community.general.parted:
         device: /dev/vdb
         number: 1
         state: present
         part_end: 2GiB
         fs_type: ext4
   
     - name: Create a ext4
       community.general.filesystem:
         fstype: ext4
         dev: /dev/vdb1
   
     - name: Create a directory if it does not exist
       ansible.builtin.file:
         path: /newpart
         state: directory
   
     - name: Mount up device
       ansible.posix.mount:
         path: /newpart
         src: /dev/vdb1
         fstype: ext4
         state: mounted
   

2. ansible-playbook 成功執行 partvg.yml 腳本。

   [deyu1@kvm19 10827000]$ ansible-playbook partedfsmnt.yml
   
   PLAY [balancers] ***************************************************************
   
   TASK [Gathering Facts] *********************************************************
   ok: [kvm15]
   
   TASK [Create a new primary partition with a size of 2GiB] **********************

   TASK [Create a ext4] ***********************************************************

   TASK [Create a directory if it does not exist] *********************************

   PLAY RECAP *********************************************************************
   kvm15 : ok=5  changed=1  unreachable=0 failed=0  skipped=0  rescued=0  ignored=0
   

3. 查看 kvm15 /etc/fstab 新增一行將 /dev/vdb1 掛載在 /newpart。

   [deyu1@kvm19 10827000]$ ansible balancers -m shell -a "grep vdb1 /etc/fstab"
   kvm15 | CHANGED | rc=0 >>
   /dev/vdb1 /newpart ext4 defaults 0 0
   

4. 查看 kvm15 掛載狀況，/dev/vdb1 已掛載在 /newpart，格式為 ext4。

   [deyu1@kvm19 10827000]$ ansible balancers -m shell -a "df -Th /dev/vdb1"
   kvm15 | CHANGED | rc=0 >>
