Datastore removal

[mohamed_abdelaa]

Dear All,

I'm facing a problem that there is a failure in one of the datastores (NAS Storage - NFS) and needs to be deleted for replacing with a new one but the problem I can't unmount or remove the datastore as the servers are in production as while trying to do so, I'm getting a message that the datastore is in use as there are vCLS VMs attached to this datastore and can't be moved or deleted (not accessible).

So, How can I remove this datastore or modify the current configurations with the replacement one ?

Thanks for your soonest help

If you are already on vSphere 7.0 Update 3, then take a look at e.g. https://www.yellow-bricks.com/2021/09/28/vsphere-7-0-u3-contains-two-great-vcls-enhancements/ for how to override the default vCLS placement, i.e. configure allowed datastores.

another issue after doing so at the vCLS VMs

"vSphere Cluster Service VM is required to maintain the health of vSphere Cluster Services. Power state and resource of this VM is managed by vSphere Cluster Services."

What should I can do for solving this issue ?

Please advise!
