Let us see how much space is busy on the VMFS datastore : df -h | grep MSA2000_LUN1.Copy the ID of your datastore in the vSphere interface, and check on the ESXi host, which device and path to the VMFS store it matches: esxcfg-scsidevs -c | grep naa.6001438005df0dee0000700004be0000 naa.6001438005df0dee0000700004be0000 Direct-Access /vmfs/devices/disks/naa.Connect over SSH to an ESXi host that has VMFS store mounted.We may need to delete the partition table of the VMFS datastore in such cases. Find the corresponding LUN in the list, select it, and click Detaches the selected device from the host.Īt times, the unmount operation still fails even after changing the paths to the log directory. Go to Manage -> Storage -> Storage Device. Let us try to unmount the datastore from the ESXi host again. 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. If the ESXi host logs are still located in the VMFS datastore (Scratch Location), we may need to check out if the datastore is specified as a location of logs in the ESXi host settings.įor this, Go to Manage -> Settings -> Advanced System Settings. This may include a directory with logs(logdir), a directory with the description of SCSI devices (sdd.sf), VMFS metadata.

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. What causes the error unable to unmount/delete VMFS Datastore: the resource is in use?

Let us today discuss the possible causes and fixes for this error. Webmasters often face the error “unable to unmount/delete vmfs datastore: the resource is in use” while removing an empty VMFS Datastore in VMWare vSphere.Īs a part of our Server Management Services, we help our Customers to fix VMware related errors regularly.
