VMware下的虚拟机扩容方式

VMware虚拟机中配置

(1)进入虚拟机设置界面,选择扩展磁盘容量。

(2) 本次是在原来30G的基础上扩展为50G。

(3)成功后发现提示,必须从客户机操作系统内部对磁盘重新进行分区和扩展文件系统,因此需要进入linux系统继续进行配置,这里配置是不会生效的。

Linux中设置

进入Linux系统,使用命令fdisk -l查看,发现实际大小为50G,但是系统已挂载的加起来是修改之前的30G。

(1) 可以看出sda3是根分区,下面按照博客提示,先删除sda3根分区,然后重新创建sda3根分区,具体参考注释。

[root@node ~]# fdisk /dev/sda
 Welcome to fdisk (util-linux 2.23.2).
 
 Changes will remain in memory only, until you decide to write them.
 Be careful before using the write command.
 
 
 Command (m for help): m
 Command action
    a   toggle a bootable flag
    b   edit bsd disklabel
    c   toggle the dos compatibility flag
    d   delete a partition
    g   create a new empty GPT partition table
    G   create an IRIX (SGI) partition table
    l   list known partition types
    m   print this menu
    n   add a new partition
    o   create a new empty DOS partition table
    p   print the partition table
    q   quit without saving changes
    s   create a new empty Sun disklabel
    t   change a partition's system id
    u   change display/entry units
    v   verify the partition table
    w   write table to disk and exit
    x   extra functionality (experts only)
 
 Command (m for help): d  ##删除分区
 Partition number (1-3, default 3): 3 ##临时先删除sda3分区
 Partition 3 is deleted
 
 Command (m for help): n #添加一个新的分区
 Partition type:
    p   primary (2 primary, 0 extended, 2 free)
    e   extended
 Select (default p): p #添加主分区
 Partition number (3,4, default 3): 3 #指定分区号3,重新创建sda3分区
 First sector (17303552-104857599, default 17303552): #回车
 Using default value 17303552
 Last sector, +sectors or +size{K,M,G} (17303552-104857599, default 104857599): #回车
 Using default value 104857599
 Partition 3 of type Linux and of size 41.8 GiB is set #提示OK
 
 Command (m for help): w #按w保存退出
 The partition table has been altered! #提示OK

(2)重启系统

重启当前系统,可以选择reboot或者init 6来执行

(3)扩容文件系统,使用命令 xfs_growfs /dev/sda3,可以看到成功扩展分区,根分区已扩容20G。

[root@node~]# xfs_growfs /dev/sda3
