Hey folks, I’m looking into what I would think would be a simple problem, but is turning out to be more complicated than I would have anticipated. A virtual machine managed by OpenNebula was blown away, but the backing RBD images remain. Upon investigating,
it appears
that the images still have watchers on the KVM node that that VM previously lived on. I can confirm that there are no mapped RBD images on the machine and the qemu-system-x86_64 process is indeed no longer running. Any ideas? Additional details
are below:
# rbd info one-73-145-10
