SMB share size dropping to 0 in SCVMM

An SMB 3.0 share size can drop to 0 in System Center Virtual Machine Manager (SCVMM) when quota reinitialization takes a long time in ONTAP due to heavy I/O, preventing new VMs from being provisioned. Resolve this issue by adjusting quota settings.

  • Issue

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

  • Cause

    If quota reinitialization takes a long time in ONTAP due to heavy I/O, new or existing SMB 3.0 share size can drop to 0 in SCVMM. When this issue occurs, new VMs cannot be provisioned on 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.
