Hi,
I wanted to use multi-backend feature with RBD/Ceph. I prepared configuration but there was still problem when i chose type volume with extra specs. In logs i can see notification that valid host not exist.
After a long search the reasons why my configuration does't work i find in cinder/volume/drivers/rbd.py that my option included in backend configuration in cinder.conf is not taken into account by RBD driver.
Below my changes:
*** 55,61 ****
super(RBDDriver, self).__init__(*args, **kwargs)
self.configuration.append_config_values(rbd_opts)
self._stats = dict(
! volume_backend_name='RBD',
vendor_name='Open Source',
driver_version=VERSION,
storage_protocol='ceph',
--- 55,61 ----
super(RBDDriver, self).__init__(*args, **kwargs)
self.configuration.append_config_values(rbd_opts)
self._stats = dict(
! volume_backend_name=self.configuration.volume_backend_name or 'RBD',
vendor_name='Open Source',
driver_version=VERSION,
storage_protocol='ceph',
***************
And now works! Hura! |
