Azure CLI vm创建和创建数据磁盘的顺序

问题描述

我正在尝试使用CLI创建Linux VM而无需任何手动步骤。 VM将运行Mongo，我想为其分配3个附加数据磁盘，这些磁盘安装在/ data / log和/ journal上

我使用的CLI命令看起来有点像：

 az vm create \ 
 --name mongo-node-1 \ 
 --resource-group myresourcegroup \ 
  - admin-username myrootuser \ 
 --custom-data" $（cat mongo-node.yml）" \ 
 --data-disks-sizes-gb 50 10 10 \ 
 --image规范：UbuntuServer：18.04-LTS：最新

我期望按照我指定的顺序创建数据磁盘：

 / dev / sdc：50 GiB 
 / dev / sdd：10 GiB 
 / dev / sde：10 GiB 

但相反磁盘以另一种顺序创建：

 / dev / sdc：10 GiB 
 / dev / sdd：50 GiB 
 / dev / sde： 10 GiB 

这是非常不切实际的，因为我想创建文件系统&将它挂载到我在启动VM时提供给Azure CLI的CloudInit userdata文件中：

 #cloud-config 
 repo_upgrade：all 
 repo_upgrade_exclude：[] 
 runcmd：
  -  echo"LC_ALL = C" | tee -a / etc / environment 
  -  echo'type = 83'| sfdisk / dev / sdc 
  -  echo'type = 83'| sfdisk / dev / sdd 
  -  echo'type = 83'| sfdisk / dev / sde 
  -  mkfs -t ext4 / dev / sdc1 
  -  mkfs -t ext4 / dev / sdd1 
  -  mkfs -t ext4 / dev / sde1 
  -  mount / dev / sdc1 / data 
  -  mount / dev / sdd1 / journal 
  -  mount / dev / sde1 / log 
  -  apt-key adv --keyserver hkp：//keyserver.ubuntu。 com：80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4 
  -  apt-get update 
  -  apt-get install -y mongodb-org 

解决方案

I'm trying to create a Linux VM using the CLI without any manual steps. The VM will run Mongo for which I want to allocate 3 additional data disks that are mounted on /data /log and /journal

The CLI command I use looks a bit like:

az vm create \
    --name mongo-node-1 \
    --resource-group myresourcegroup \
    --admin-username myrootuser \
    --custom-data "$(cat mongo-node.yml)" \
    --data-disk-sizes-gb 50 10 10 \
    --image Canonical:UbuntuServer:18.04-LTS:latest

I'm expecting the creation of the data disks to be completed in the order I specified:

/dev/sdc: 50 GiB
/dev/sdd: 10 GiB
/dev/sde: 10 GiB

But instead the disks are created in another order:

/dev/sdc: 10 GiB
/dev/sdd: 50 GiB
/dev/sde: 10 GiB

Which is very impractical because I want to create the filesystem & mount it in the CloudInit userdata file I'm supplying to the Azure CLI when launching the VM:

#cloud-config
repo_upgrade: all
repo_upgrade_exclude: []
runcmd:
- echo "LC_ALL=C" | tee -a /etc/environment
- echo 'type=83' | sfdisk /dev/sdc
- echo 'type=83' | sfdisk /dev/sdd
- echo 'type=83' | sfdisk /dev/sde
- mkfs -t ext4 /dev/sdc1
- mkfs -t ext4 /dev/sdd1
- mkfs -t ext4 /dev/sde1
- mount /dev/sdc1 /data
- mount /dev/sdd1 /journal
- mount /dev/sde1 /log
- apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
- apt-get update
- apt-get install -y mongodb-org

For this to work I need to be sure upfront which of the created devices is the 50GB disk, because I don't want to use a 10GB disk as the data storage: those are used for the journal and log files. And I don't see how I can do this with the Azure CLI...
