Now, restart the ESXi host or restart the Syslog Server service on the host. If it specifies the VMFS datastore in it, change the path to the logs directory.

Find ScratchConfig.CurrentScratchLocation and.

The datastore is not a part of the Datastore Cluster.

Storage I/O Control is disabled for datastore.

There are no virtual machine, template, snapshot, or ISO image files on VMFS datastore (we must migrate the VMs to another VMFS Datastore, power off and remove them, or unregister VMs in vSphere).

This generally happens while trying to unmount the VMFS Datastore from ESXi hosts.īased on the error, it is clear that the VMFS datastore cannot be removed since ESXi hosts or vSphere are still using storage to write some data.Īccording to the VMWare documentation, when removing LUN from vSphere we should check the following points: Cannot unmount volume Datastore Name VMFS “file system is busy”. The resource 'Datastore Name: MSA2000_LUN1 VMFS uuid: xxxxx-xxxxx-x-xxxxx-xxxx' is in use. Often while migrating virtual machines files from old storage to a new storage system users faces the error message as shown below: Unmount VMFS volume.
