我有一个带有 2 个网络接口的虚拟机，eth0 和 ens10。

所以目前我使用这个：

- name: Add IP address of all hosts to all hosts
  lineinfile:
    dest: /etc/hosts
    regexp: '.*{{ item }}$'
    line: "{{ hostvars[item].ansible_host }} {{item}}"
    state: present
  when: hostvars[item].ansible_host is defined
  with_items: "{{ groups.all }}"

但这只会添加 Ansible 文件中指定的主机 IP（这是 eth0 interafce）。

我想将ens10接口IP添加到hosts文件中。

我有一个带有 1 280GB 磁盘的虚拟机。出于某种原因，我的布局是：

$ df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/centos-root   50G   21G   30G  41% /
devtmpfs                 5.8G     0  5.8G   0% /dev

tmpfs                    1.2G     0  1.2G   0% /run/user/1000

运行 fdisk -l：

$ sudo fdisk -l

和：

如何将用于 /dev/mapper/centos-home 的磁盘空间移动到 /dev/mapper/centos-root？我必须缩小 centos-home 并重新分配给 centos-root 吗？

我有一个增加磁盘的 SUSE VM (11.4)。我正在遵循指南（http://www.techrepublic.com/blog/smb-technologist/extending-partitions-on-linux-vmware-virtual-machines/）。这增加了 sda3。

我到了vgextend [volume group] /dev/sdaX，vgextend rootfs /dev/sda3

但它说没有找到卷组。当我运行 fdisk -l

Disk /dev/sda: 220.1 GB, 220117073920 bytes
255 heads, 63 sectors/track, 26761 cylinders, total 429916160 sectors

Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Device Boot      Start         End      Blocks   Id  System

/dev/sda3       220200960   429916159   104857600   83  Linux

和 df -h：

Filesystem            Size  Used Avail Use% Mounted on
rootfs                 99G   93G  1.4G  99% /

/dev/sda1              99G   93G  1.4G  99% /

我还运行了vgdisplay，上面写着“未找到卷组”。
