Hello Erlon,
Yes, my class inherits from filters.BaseHostFilter.
That's what I though for 'scheduler_available_filters' , is this option
required for newer release ?
This option is mentioned here :
http://docs.openstack.org/developer/cinder/devref/filter_scheduler.html
The test filter is:
> from cinder.openstack.common..scheduler import filters
> from cinder.openstack.common import log as logging
>
> LOG = logging.getLogger(__name__)
>
> class CustomFilter(filters.BaseHostFilter):
> def host_passes(self, host_state, filter_properties):
> LOG.warn("Attributes of host_state: " + str(dir(host_state)))
>
> if host_state.host == "host1.xxx.xxx":
> LOG.warn("Don't want you: " + host_state.host)
> return False
> return True
I'll look into host_manager.py but I'm not sure what more it can give me.
Thanks,
Thomas
