How to disable cephfs?

I set up a home lab of 3 machines to set up a proxmox cluster so I could learn how to do it. I got through the ceph setup and started setting up a cephfs, but when I set it up, for some reason, I cannot create any VMs on it, and can only use the storage local to each host. I found the content was set to just Backup, ISO image, Container template.

I guess this was by default, but I cannot fathom why that would be default. So, then I have been trying to delete the cephfs and recreate it to make it usable for VMDisks, but I go through the steps, and it tells me "storage 'cephfs' is not disabled, make sure to disable and unmount the storage first".

I saw I missed a step "Disable all related CephFS Proxmox VE storage entries (to prevent it from being automatically mounted)." However, I cannot seem to find HOW to do this step. I find no instructions ANYWHERE on how to do this. It's sitting there in the inventory of my VM, Enabled, inactive, and no MDS. So, I can't actually do anything with it and can't delete it. It's quite annoying.

Does anyone out there have the process for "Disable all related CephFS Proxmox VE storage entries (to prevent it from being automatically mounted)."?
 
Nevermind. Just found it in a very unexpected place.
Great!
Please tell us where that was and set the topic of this thread to "Solved" (by editing the title, there is a drop-down box).

That particular step is not in the Ceph area like everything else dealing with this. It is in the Datacenter Storage configuration.

Select the Datacenter in the far left area
Select Storage in the next frame to the right
Find the Cephfs datastore in the main frame, and then click the Remove button at the top
