vagrant 设备上没有剩余空间 [英] vagrant no space left on device
问题描述
今天我开始在简单的操作上出错，比如在 vim 中创建小文件，bash 完成也开始抱怨.
Today I started getting errors on simple operations, like creating small files in vim, the bash completion started to complain as well.
这是df -h的结果:
vagrant@machine:/vagrant$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 40G 38G 249M 100% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
udev 2.0G 12K 2.0G 1% /dev
tmpfs 396M 396K 395M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 2.0G 0 2.0G 0% /run/shm
none 100M 0 100M 0% /run/user
overflow 1.0M 148K 876K 15% /tmp
192.168.50.1:/Users/nha/repo/assets 233G 141G 93G 61% /var/www/assets
vagrant 233G 141G 93G 61% /vagrant
那么显然 / 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?
So apparently / doesn`t have space anymore ? Isn't it weird since I have space in the other filesystems (or am I misreading something) ?
如何在我的虚拟机上获得更多空间?
How do I get more space on my vm ?
推荐答案
即使您的来宾操作系统上有空间，虚拟机也是有限的.为了增加磁盘的大小，需要几个步骤:
Even though you have space on your Guest OS, the VM is limited.There are couple of steps required in order to increase the size of your disk:
首先，vagrant halt关闭你的虚拟机
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 Virtual box 并更改 VM 的配置以关联新磁盘
start Virtual box and change configuration of the VM to associate the new disk
使用 fdisk 调整磁盘大小
你需要用新的空间创建一个新的分区并分配它，所以首先启动VM并以超级用户身份登录
you need to create a new partition with the new space and allocate it, so first start the VM and logged on as super user
vagrant up && vagrant ssh

命令(如我的实例所示)是
the command (as illustrated from my instance) are
[root@oracle ~]# fdisk /dev/sda

sectors (command 'u').

The partition table has been altered!

[root@oracle ~]#
注意与您的配置相比，您可能需要更改/dev/sda
note you might need to change /dev/sda compare to your configuration
创建一个新分区(再次以超级用户su - 登录)
create a new partition (again logged on as super user su -)
