Hi all
we have installed a Havana OpenStack cluster with RBD as the backing storage
for volumes, images and the ephemeral images. The code as delivered in
https://github.com/openstack/nova/blob/master/nova/virt/libvirt/imagebackend.py#L498
fails, because the RBD.path it not set. I have patched this to read:
@@ -419,10 +419,12 @@ class Rbd(Image):
if path:
try:
self.rbd_name = path.split('/')[1]
+ self.path = path
except IndexError:
raise exception.InvalidDevicePath(path=path)
else:
self.rbd_name = '%s_%s' % (instance['name'], disk_name)
+ self.path = 'volumes/%s' % self.rbd_name
self.snapshot_name = snapshot_name
if not CONF.libvirt_images_rbd_pool:
raise RuntimeError(_('You should specify'
but am not sure this is correct. I have the following problems:
1) can't inject data into image

directory))
possibly the self.path = … is wrong - but what are the correct values?
2) Creating a new instance from an ISO image fails completely - no bootable
disk found, says the KVM console. Related?
3) When creating a new instance from an image (non ISO images work), the disk
is not resized to the size specified in the flavor (but left at the size of the
original image)
I would be really grateful, if those people that have Grizzly/Havana running
with an RBD backend could pipe in here…
thanks
