cannot unmount volume 'datastore' because one or more virtual machines are still registered on it. correct the problem and retry the operation.
I recently encountered this problem; I attempted to unmount but received this error.
Examine the datastore to see if there are any virtual machines or files.
--Ensure that there are no VMs or VM templates in that datastore, as well as that there are no VCLs VMs.
--All CD/DVD images on the VMFS datastore must be unmounted/unregistered from the virtual machines as well.
-- Connect to the ESXi host via SSH
--grep datastore-name | lsof
--lsof | grep datastore uuid
--lsof | grep datastore LUN-id (naa.xxx)
--All three of the preceding commands should generate no output== indicating that no active process is accessing the datastore.
--Run the storage core device world command using the esxcli command.
--Run esxcli storage core device world list -d naa.XX to ensure that no active threads access the LUN.
- used to unmount the datastore from each host
storage filesystem unmount -l datastore-name esxcli
--The dismount was successful.
--started a cluster-level re-scan
My case study The VCLS VMs are in the datastore. I disabled VCLS virtual machines at the cluster level.
To collect domain ID, when we selected the any cluster , it will display the one domain ID in main page URL.
Note: each cluster having own domain ID.
> VM's are powered and deleted automatically when I made change from true to False.
> Unmount the datastore from vCenter/Esxi hosts.
> Enable again those settings from False to True.
> VCLS VMs are redeployed on cluster and working fine.
