  • Issue

    New or existing SMB 3.0 share size can drop to 0 in System Center Virtual Machine Manager (SCVMM).

  • Cause

    This issue occurs when quota reinitialization takes a long time in Data ONTAP due to heavy I/O, new or existing SMB 3.0 share size can drop to 0 in SCVMM. Because of this, new VMs cannot be provisioned on the new or existing SMB 3.0 shares.

  • Corrective action

    1. Turn off the quotas.

    2. Add one default quota rule of type “tree” on each volume hosting SMB shares.

    3. Turn on the quotas for those volumes to which you added a default quota rule and restart SMI-S Provider.
