[英]How to increase harddisk size of Azure VM
我正在使用類型為RHEL OS類型的Azure VM。 當前,我正在使用標准D3 v2大小的VM。 我在VM中僅看到32個硬盤存儲空間。 如何增加硬盤大小?
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:我正在使用非托管磁盤。
因此,基本上請遵循以下文章: https : //docs.microsoft.com/zh-cn/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
根據您的描述,我在實驗室中進行了測試,並且在Red Hat Enterprise Linux Server release 7.3 (Maipo)
。
注意:當您這樣做時,強烈建議您可以備份OS VHD。 如果失敗,則無法啟動VM。
1.在Azure Portal上停止VM。
2.使用Azure CLI增加OS磁盤。
az vm update -g shui -n shui --set storageProfile.osDisk.diskSizeGB=100
3.啟動您的VM並SSH到您的VM。 您可以檢查df -h
和fdisk -l
。 /dev/sda2
不會增加到100GB。 您需要執行以下命令。
sudo -i
[root@shui ~]# fdisk /dev/sda

4,重啟虛擬機
5.SSH到您的VM並調整文件系統大小。
xfs_growfs -d /dev/sda2
現在,您可以使用df -h
檢查操作系統磁盤
[root@shui ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 100G 1.7G 98G 2% /
