流浪者在设备上没有剩余空间

Question

今天我开始在简单操作上遇到错误,比如创建小文件vim,bash完成也开始抱怨.

结果如下df -h:

vagrant@machine:/vagrant$ df -h
Filesystem                           Size  Used Avail Use% Mounted on

vagrant                              233G  141G   93G  61% /vagrant

所以显然/没有空间了？因为我在其他文件系统中有空间(或者我误读了什么),这不是很奇怪吗？

如何在我的虚拟机上获得更多空间？

Answer 1

即使您的Guest OS上有空间,VM也是有​​限的.为了增加磁盘大小,还需要几个步骤:

首先,vagrant halt关闭你的VM

调整磁盘大小

VBoxManage clonehd box-disk1.vmdk box-disk1.vdi --format vdi
VBoxManage modifyhd box-disk1.vdi --resize 50000

启动虚拟框并更改VM的配置以关联新磁盘

使用fdisk调整磁盘大小

您需要使用新空间创建一个新分区并进行分配,因此首先启动VM并以超级用户身份登录

vagrant up && vagrant ssh
su -

命令(如我的实例所示)是

[root@oracle ~]# fdisk /dev/sda

[root@oracle ~]#

请注意,您可能需要更改/ dev/sda与您的配置进行比较

创建一个新分区(再次以超级用户身份登录su -)
