That's the good thing to hear when you unable to remove the datastore. At least your original VMs are there. BTW, since you already backup your VM. Please identify whether your VMs are still running from older datastore or not. I think that's probably why you we unabled to remove it.
The datastore I am trying to delete is empty. I move the fodler containing VMDK files to a different datastore. I have HA turned on those 2 hosts and I have a cluster config.
Let me explain my problem:
One VM had 3 hard drives. 2 under one datastore (working fine) and one drive under the problematic datastore that is inactive. I can't boot the VM because of that. Because I am missing that datastore. I know I probably assign a new signature to that inactive datastore. I am really trying to get that VM back online if i can fix that 3 drive (meaning relocating to the right datastore and have the vmx file edited to reflect so). Does that make sense?
I removed the VMs from the inventory and recreated the VM by pointing to the good datastores. The VMs booted up fine. But i still can't delete that inactive datastore that has been giving me trouble. Under Inventory, Datastores for that inactive datastore, I select the Summary tab, then under General it says "Virtual Machines and Templates: 1". But if I try to browse that datastore, there is absolutely nothing. It's empty. Any ideas?
Rebooting the 2 hosts fixed the problem of deleting that "ghost" datastore... I was WAY too nervous to do anything since I got my VMs back online. But i guess I had to reboot at some point in the future. What a 4th of July......
