mount 模組 - 掛載檔案系統

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。

   ceuser@deyu:~/ansible_pb$ vi partedfsmnt.yml
   ceuser@deyu:~/ansible_pb$ cat partedfsmnt.yml
   ---
   - hosts: balancers
     tasks:
     - name: Create a new primary partition with a size of 1.2GiB
       community.general.parted:
         device: /dev/vdb
         number: 1
         state: present
         part_end: 1.2GiB
         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。

   ceuser@deyu:~/ansible_pb$ ansible-playbook partedfsmnt.yml
   
   PLAY [balancers] ***************************************************************
   
   TASK [Gathering Facts] *********************************************************
   ok: [kvm15]
   
   TASK [Create a new primary partition with a size of 1.2GiB] ********************

   PLAY RECAP *********************************************************************
   kvm15  : ok=5  changed=2  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。

   ceuser@deyu:~/ansible_pb$ 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。

   ceuser@deyu:~/ansible_pb$ ansible balancers -m shell -a "df -Th /dev/vdb1"
   kvm15 | CHANGED | rc=0 >>
   Filesystem     Type  Size  Used Avail Use% Mounted on
   /dev/vdb1      ext4  1.2G   24K  1.1G   1% /newpart
