Manchine_temporaryStorage.vmdk file growth unexpectedly

[Arun Kumar K R]

Hi All,

 

Need suggestion.

We have noticed on VMware end, the Storage Usage for each VM is getting increased regularly. On analyzing VMName_temporaryStorage.vmdk file size getting increased on every reboot. 

MCSWCDisk is getting freedup on reboot as expected.

  

DDC : 1912

VDA : 1912 CU2

OS : Windows 2012

RAM : 16GB

CPU : 2

HDD : 280GB (thin)

Provisioned Method : MCS

MCSWCDisk : 280 GB (thin)

 

We have rebuild a machine to test but same behavior noticed. 

Could you please guide me if any one noticed this behavior. 

 

Also, once the Storage Usage for VM shows one value it cant reduce. is it correct ? example: Storage usage shows as 100GB on VM console for a VM, this value cannot reduced though the usage on the VM is less.
