An attempt to delete NFS datastore from a ESXi host returns the error: Sysinfo error on operation returned the following status: Busy Which two statements could explain this failure? (Choose two.)

Membership in a Storage DRS cluster prevents datastore removal through a different enforcement mechanism - an error indicating the datastore is managed by SDRS - rather than the generic 'Busy' status message.

NFS.VolumeRemountFrequency is a host advanced configuration parameter that controls automatic remount retry timing after NFS connectivity loss and has no bearing on the 'Busy' condition encountered during a manual datastore deletion.

Storage I/O Control (SIOC) continuously monitors datastore I/O latency and injects congestion control, which keeps an active handle on the datastore. ESXi reports the datastore as 'Busy' because SIOC must be disabled before the datastore can be unmounted and removed.

If any virtual machines are powered on or registered on the NFS datastore, ESXi holds the datastore open and returns a 'Busy' error during a removal attempt; all VMs must be powered off, migrated, or unregistered before the datastore can be deleted.
