Storage Pool "SU1_Pool" is not in Mirror mode, one hard disk failing move VMs to"Saved-critical' state with the exception of MAS-DC01 (running) RRS feed

  • Question

  • Hello,

    I actually have such disk configuration  - 2 * 300 GB for base OS, 5 * 300 GB for Data for MAS.

    I installed a couple of times  April 2017 MAS TP3. After some days one of the hard disk was going to failed state and VMs were moved to"Saved-critical' state with the exception of MAS-DC01 (running). 

    When I tried to remove failed disk from Storage Pool I received this error - "This physical disk is used by one or more virtual disks that use the Simple (no resiliency) layout. To remove this physical disk, delete the following virtual disks SU1_Volume_1"

    I checked at CloudDeployment\Configuration\Roles\Infrastructure\Storage\Role.xml and found 

    "StoragePool Name="SU1_Pool" ReserveCapacityForRebuild="1" ResiliencySettingName="Mirror""

    This situation was repeated.

    So my question is why VMs were moved to"Saved-critical' state and why Storage Pool "SU1_Pool" is not in Mirror mode?

  • Hi,

    Unfortunately you disk configuration does not meet our minimum requirements.

    To get mirroring you need at least 2TB, 8 disks. 

    The POC is not designed to be a resilient configuration.

    Thanks

    Daniel
