The issue is that the fix was only partially successful, in that whilst
it avoids the 'storage.zfs_pool_name', the other branch of code doesn't
get the zfs pool name, but instead the lxd pool name; if they are
different then it fails.
The LXD charm used different names (it's now being patched to use the
same name for the lxd pool and zfs pool), which broke nova-lxd on
bionic.
The code in question is in nova/virt/lxd/driver.py in
get_available_resource(self, nodename) around line 1057:
- try:
- pool_name = lxd_config['config']['storage.zfs_pool_name']
- except KeyError:
- pool_name = CONF.lxd.pool
- local_disk_info = _get_zpool_info(pool_name)
+ try:
+ pool_name = lxd_config['config']['storage.zfs_pool_name']
+ except KeyError:
+ pool_name = CONF.lxd.pool
+ local_disk_info = _get_zpool_info(pool_name)
i.e. storage.zfs_pool_name vs CONF.lxd.pool
When nova-lxd is properly refactored for storage pools, this issue
should be resolved.
