vmware虚拟机linux怎么扩展硬盘大小

Posted 2023-04-11

1、在vmware启动界面中选择VM菜单下的Settings来增加磁盘，然后选择add,选择hard disk，点击Next。
2、选中create a new virtual disk，点击下一步，选择scsi，继续下一步。选择要新增磁盘的大小，勾选Allocate all disk space now立即分配空间，下一步，在你的硬盘上选择一个目录来创建，点击完成结束。这样，一个新增的空间就创建好了。
3、进入Linux系统，使用fdisk -l可以看到新添加的硬盘，给新的硬盘分区、格式化磁盘，最后在用户主目录下新建一个文件， 如/home/linux/newdisk。把新增的分区mount到这个目录下即可。 参考技术A vmware安装目录下有个vmware-vdiskmanager.exe， 用这个命令可以增加磁盘空间，我以前用过，但是一旦增加了貌似不能缩小了具体命令，百度下吧，有详细流程说明

虚拟机中Opensuse扩展分区大小

一、Virtual Machine 扩展硬盘大小

在vmware虚拟机中设置 硬盘大小，扩展至需要的大小。这里简要略去。

然后进入系统； 

sudo parted     //启动parted

(parted) print list 
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 129GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number Start End Size Type File system Flags
1 1049kB 2155MB 2154MB primary linux-swap(v1) type=82
2 2155MB 27.3GB 25.2GB primary btrfs boot, type=83
3 27.3GB 64.4GB 37.1GB primary xfs type=83

(parted) help
align-check TYPE N check partition N for TYPE(min|opt) alignment
help [COMMAND] print general help, or help on COMMAND
mklabel,mktable LABEL-TYPE create a new disklabel (partition table)
mkpart PART-TYPE [FS-TYPE] START END make a partition
name NUMBER NAME name partition NUMBER as NAME
print [devices|free|list,all|NUMBER] display the partition table, available devices, free space, all found partitions, or a particular partition
quit exit program
rescue START END rescue a lost partition near START and END
resize NUMBER END change end sector of partition NUMBER
rm NUMBER delete partition NUMBER
select DEVICE choose the device to edit
disk_set FLAG STATE change the FLAG on selected device
disk_toggle [FLAG] toggle the state of FLAG on selected device
set NUMBER FLAG STATE change the FLAG on partition NUMBER
toggle [NUMBER [FLAG]] toggle the state of FLAG on partition NUMBER
unit UNIT set the default unit to UNIT
version display the version number and copyright information of GNU Parted
(parted) print devices 
/dev/sda (129GB)

 

(parted) print all 
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 129GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number Start End Size Type File system Flags
1 1049kB 2155MB 2154MB primary linux-swap(v1) type=82
2 2155MB 27.3GB 25.2GB primary btrfs boot, type=83
3 27.3GB 64.4GB 37.1GB primary xfs type=83

parted之后执行print free ，会发现多出来的空间Free Space.

(parted) print free
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 129GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

32.3kB 1049kB 1016kB Free Space
1 1049kB 2155MB 2154MB primary linux-swap(v1) type=82
2 2155MB 27.3GB 25.2GB primary btrfs boot, type=83
3 27.3GB 64.4GB 37.1GB primary xfs type=83
64.4GB 129GB 64.4GB Free Space

(parted) resize 3
Error: Partition /dev/sda3 is being used. You must unmount it before you modify it with Parted.
(parted) quit
suse@linux-nhtn:~> sudo umount /dev/sda3 
umount: /home: target is busy
(In some cases useful info about processes that
use the device is found by lsof(8) or fuser(1).)

suse@linux-nhtn:~> sudo parted

由于 umount: /home: target is busy，所以利用GParted Live CD来进行分区，有点像WIN PE.

当然如果能够umount  /home;也可以利用 parted 进行resize。ref：用parted调整分区大小

二、操作系统扩展分区

1. 下载GParted Live CD 0.25.0-3； (因为必须在分区被umount的情况下才能扩展分区）

2. Vmware 启动后 按F2 从光盘加载GParted Live CD

3. 选择Simplified Chinese语言，进入Live系统，启动GParted 软件；选择中需要调整的分区---->右键-更改大小---->调整分区--->点击工具栏Apply执行。

点击Apply执行结果如下：

 

异常情况处理：

   xfs_repair

ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair.  If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.

检查后重新挂载OK

[root@gpsg32 ~]# xfs_ncheck /dev/sda3  

这里会将该盘上的文件检查一遍，你会看到熟悉的文件。

[root@gpsg32 ~]# df -h

这时候再重新启动GParted，按照正常步骤操作。

祝好运！
