The correct answer is A. Storage vMotion any virtual machines on the datastore to another location. The 'Busy' error when deleting an NFS datastore means virtual machines are still registered or running on it; Storage vMotion relocates those VMs so the datastore can then be unmounted and deleted.

Question

Deletion of an NFS datastore generates the following error:

Sysinfo error on operation returned the following status: Busy Which step can be performed that will allow the deletion to complete successfully?

Options

  • AStorage vMotion any virtual machines on the datastore to another location.
  • BRemove the datastore from the Storage DRS cluster in which it resides.
  • CVerify the value of the NFS.HeartbeatDelta is not set to 0.
  • DSuspend any running virtual machines and unmount the NFS datstore.

Why each option

The 'Busy' error when deleting an NFS datastore means virtual machines are still registered or running on it; Storage vMotion relocates those VMs so the datastore can then be unmounted and deleted.

AStorage vMotion any virtual machines on the datastore to another location.Correct

The 'Busy' status indicates that one or more virtual machines have files (vmx, vmdk, etc.) residing on the NFS datastore. Storage vMotion live-migrates the VM storage to another datastore while the VM remains running, clearing the busy condition and allowing the deletion to proceed.

BRemove the datastore from the Storage DRS cluster in which it resides.

Removing the datastore from a Storage DRS cluster does not evacuate VM files from the datastore, so the underlying busy condition caused by active VM registrations remains.

CVerify the value of the NFS.HeartbeatDelta is not set to 0.

NFS.HeartbeatDelta controls the tolerance window for NFS heartbeat monitoring and has no effect on whether a datastore is considered busy by active VM file handles.

DSuspend any running virtual machines and unmount the NFS datstore.

Suspending VMs leaves their files on the NFS datastore and their registrations intact, so the datastore remains busy and cannot be deleted.
