Unmount/Mount Datastore from Esxcli


Before taking any action, please remember to shut down and unregister possible VM's associated to the datastore on interest

Step 2: List all datastores on the system

  • esxcli storage nfs list

Step 3: Unmount the datastore 

After you listed the datastores registered on the system you can confirm the name of the one your interest to unmount using:

  •  esxcli storage nfs remove -v <datastorename>

Know error:

If the output for the unmount process results in something similar to :

  • "Sysinfo set operation VSI_MODULE_NODE_mnt_umount failed with error status Busy" 
    Please consider taking a look on the vmdk of the vm, it's mostly provable that the VM has vmdk shared with other datastores and vm's
