Having issue adding a data disk to an existing scale set(created by ACS) #37

Open sensre opened 6 years ago

sensre commented 6 years ago

Having issue adding a data disk to an existing scale set. and this vmss created by ACS swarm cluster. there is no option in GUI to add an additional disk to each instance of VM. Below I got it from CLI. Any recommendations or inputs.?

"az vmss disk attach -g dcospx -n dcospx --size-gb 100 --lun 3 The Resource 'Microsoft.Compute/virtualMachineScaleSets/dcospx' under resource group 'dcospx' was not found."

Hi, a couple of things to check..

  1. Double check in the portal that there is a scale set called dcospx in resource group dcospx.
  2. You can only add data disks to scale sets that were created based on Azure Managed Disks. If your ACS cluster created a scale set based on unmanaged disks (i.e. you see a set of 5 storage accounts that were created for the scale set) then you can't add attached disks for it.
    • I just confirmed with the ACS folks that DCOS and Swarm clusters created using ACS do use Managed Disks, so you should be fine (unless you created this a long time ago). Double check you have the right VMSS name, resource group, and subscription set.

Thanks for your response. So by default ACS cluster creates unmanaged disk and not able to add the more disk to it.

Is it a limitation? Then acs cluster use case will less.

Thanks again

@senpx No. My response was that by default ACS does create Managed Disk based scale sets for DCOS and Swarm.
