我使用的是RHEL OS类型的Azure VM。目前我正在使用标准D3 v2大小的VM。我看到VM中只有32个硬盘存储空间可用。如何增加硬盘的大小?

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2        32G   32G  185M 100% /
devtmpfs        6.9G     0  6.9G   0% /dev
tmpfs           6.9G     0  6.9G   0% /dev/shm
tmpfs           6.9G  8.4M  6.9G   1% /run
tmpfs           6.9G     0  6.9G   0% /sys/fs/cgroup
/dev/sda1       497M  117M  381M  24% /boot
/dev/sdb1       197G  2.1G  185G   2% /mnt/resource
tmpfs           1.4G     0  1.4G   0% /run/user/1000

注意:我使用的是非托管磁盘。

如果您的虚拟机是使用Azure资源管理器(ARM)创建的,则可以调整新Azure门户中的操作系统磁盘或数据磁盘的大小。

  1. 导航到要调整磁盘大小的Azure Resource Manager虚拟机。
  2. 从Azure门户关闭虚拟机。等到它完全关闭(取消分配)。
  3. 在“设置”边栏选择“磁盘”(如下图所示)。
  4. Disks settings blade

    1. 选择要调整大小的操作系统或数据磁盘。
    2. 在新刀片上,输入新磁盘大小(每个磁盘最大1023GB或1TB)(如下图所示)。
    3. Change disk size

      1. 点击“保存”。
      2. 再次启动虚拟机。
      3. 就是这样!您可以登录VM并检查您是否具有新选择的磁盘大小。

所以基本上遵循这篇文章:https://docs.microsoft.com/en-us/azure/virtual-machines/linux/expand-disks

az vm deallocate --resource-group myResourceGroup --name myVM
az disk list \
    --resource-group myResourceGroup \
    --query '[*].{Name:name,Gb:diskSizeGb,Tier:accountType}' \
    --output table
az disk update \
    --resource-group myResourceGroup \
    --name myDataDisk \
    --size-gb 200
az vm start --resource-group myResourceGroup --name myVM

根据你的描述,我在我的实验室测试,我在Red Hat Enterprise Linux Server release 7.3 (Maipo)上进行测试。

  

注意:当你穿上它时,我强烈建议您备份你的操作系统VHD。如果你   失败了,你无法启动你的虚拟机。

1.在Azure门户上停止虚拟机。

2.使用Azure CLI增加操作系统磁盘。

az vm update -g shui -n shui --set storageProfile.osDisk.diskSizeGB=100

3.启动VM和ssh到VM。您可以查看df -hfdisk -l/dev/sda2不会增加到100GB。您需要执行以下命令。

sudo -i

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

4.重新启动虚拟机

5.SSH到您的VM并调整文件系统的大小。

xfs_growfs -d /dev/sda2

现在,您可以使用df -h

检查您的操作系统磁盘
[root@shui ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2       100G  1.7G   98G   2% /
