As cinder already supports volume types, it's time
to be added in Horizon. The types are added in admin panel.
A volume can either have a *valid* type, or None.
There are two minor issues:
1. When a type is deleted, if there is a volume with
this type, the type is returned as the id,
instead of the name. Which is good as consistency,
but maybe a type should not be deleted if used by a volume?
2. If no vol type is passed(None) value, the type is being
assigned as 'None', and returned as a string('None')
3. In the create volume type form, the 'Description' is
empty at the moment, I couldn't find any help info
to add for volume types...
Implements blueprint volume-types
Tested with n-cinder and n-vol services. Since Folsom both
support volume-types. I'm not sure if it is possible a grizzly
Dashboard to work with essex nova, which could be a problem.
Dashboard doesn't seem to provide permissions based on tables,
so if it needs to check if a service is available to show/hide
volume types, this will need some more effors to implement
permissions on table/action level. Or maybe this needs to be
added as a standalone panel?
Patch set 2: implemented suggestions, added one more thing:
When creating a volume from a snapshot, set the volume type
initial as the type of the original volume from which
the snapshot is being created.
Patch Set 3: Updated the description of volume types,
based on the notes from:
https://etherpad.openstack.org/grizzly-cinder-volumetypeshttps://etherpad.openstack.org/cinder-usecases
Any feedback on the description is welcome.
