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 successf

Storage vMotion live-migrates all virtual machine disk files and configuration from the NFS datastore to another location while the VMs remain running, eliminating all active file handles and allowing ESXi to unmount and delete the datastore without a busy conflict.

Removing the datastore from a Storage DRS cluster only changes cluster membership; it does not migrate any VM files or release the open file handles that are causing the busy state.

NFS.HeartbeatDelta controls how ESXi evaluates NFS connectivity heartbeats and has no effect on whether a datastore has open file handles from running VMs.

Suspending VMs pauses CPU and memory but leaves all VMDK and configuration files open on the datastore, so the busy condition remains and the deletion still fails.
