LVM storage disk's 'Remove' button greyed out when browsing storage

[JustaGuy]

Hi,Today I wanted to delete a KVM's disk from LVM storage, but couldn't do anything more than remove the entry from the 'Hardware' tab, because the 'Remove' button was greyed out in that LVM storage page.I was finally able to delete it by removing the VM entirely, which was less than an ideal solution.Later I remembered I could've used lvremove in an ssh session.How can I delete disks? Do I always have to use the command line? Why are my 'Remove' buttons greyed out?

I know this is an old Post but I have the same Problem - the storage in Question is a md raid with lvm on top. Deleting an disk image that was moved to another storage is not possible...

/edit: Okay, one needs to remove the disk images from the vms ("Unused disk image")...
