sweetgerma.blogg.se - Why cannot unmount disk

You may see some inaccessible VM which are actually vCLS VM's GUID which we deleted when host were down.

Turn off vSAN service after successful unmount of remote datastore.įinal step is for clean up.

Just click on unmount and it will remove it.

Select the desired vSAN datastore and now Unmout option will be highlighted.

Now navigate to Remote cluster "Configure" -> vSAN -> Remote Datastores.

You may see some error while deploying the new vCLS VM which we can ignore.

Add then back to same vSAN remote HCI cluster."HCI vSAN Ready" and let them in Maintenance mode.

Power On back those host which was removed in Step 1.

Now select the vCLS VM that were used in remote vSAN cluster "HCI vSAN Ready" and delete them. Navigate to Main vSAN Cluster and select the File Tab.

Shutdown hosts which we take out of cluster under MM.Move out the hosts which were maintenance mode, out of cluster to directly vCenter/Folder.Put all host from "HCI ready clsuter" (remote vSAN cluster) in Maintenance Mode.This issue occurred because my lab environment was on purely vSAN and vCLS vm's were created on vSAN datastore which not allowed to delete and due to that Unmout was grayed out. First solution i marked as best and easy one because it was looks so easy and promising. I solved this problem by myself and for that i tried different approach but not sure if that all were correct way to do or not. Not even it was allowed to turn off vSAN services on remote vSAN cluster.

I even tried to remove all hosts from cluster then even it was not allowed to unmount the remote vSAN datastore and not even allowing to delete empty cluster. I found an document from Vmware on unmount the Remote vSAN datastore but unfortunately the option mentioned in document was not really exist in my case that i assume.

Now problem is unmount operation can't be done unless all VM's will be evacuated or deleted, another problem is system not allowing to delete/manage vCLS VM's. Now the problem occurred when i was done with my testing and trying remove the newly created cluster by simply un-mounting the remote datastore, Option was grayed outand saying that "Cannot unmount the datastore because this cluster has registered virtual machines on it." where actually i don't have any running VM left in cluster, it was because of another feature of Vsphere 7 U1 called as vCLS which itself a great thing introduced and very helpful while vCenter temporally Maintenance/Disconnect but the thing is that it create hidden service VM's which actually created on the vSAN datastore which was mounted remotely from the existing vSAN. All seems pretty good and easy to configure the HCI Mesh vSAN, In my lab i already had a cluster "Main vSAN Cluster" which using the local vSAN with local disk on each Esxi host, I created another cluster where i added newly created Esxi hosts (vSAN ready) which don't have there own local disk installed and i successfully able to mount the existing vSAN datastore as remote datastore in new cluster which had only 2 nodes (esxi 7.0.2) installed. Happy to see the new feature introduced with vsphere 7.0.1 HCI Mesh vSAN which allow to share the existing vSAN with other cluster having HCI ready Nodes without local disk. I am writing this as question because not sure what i did to resolve this issue was correct way to do or not.
