Indeed. As explained in #565676, lvm2 only activates the VGs containing the root, /usr and hibernate/resume devices (and only if it can recognise that they are on LVM). Apparently it is not generally safe to activate all visible VGs. But perhaps that behaviour should be available as an *option*. That is safe for most systems and I think it would resolve all the issues blocking this. (I don't really understand the purpose of running btrfs on LVM, though. btrfs integrates logical volume management and I was under the impression that that's the main reason to use it. If you still need another layer underneath then why use it at all?) Ben. -- Ben Hutchings Humour is the best antidote to reality.
