the volume's volume_type_id is null

[张恒]

if you have multy cinder driver,
when start a vm,the vm's system volume will do not ses volume type in dashboard,
and check the database,in the table(cinder.volumes) ,the colume volume_type_id is null.
but create a single volume,you can choose a volume_type,the value will be writed in cinder.volumes.volume_type_id,and will see volume type in volums list

Sorry, can you clarify what the error is you are seeing. I'm not sure I'm following.

there is no error,only in the table of cinder.volumes ,the volume_type_id is null,when i create a vm,so the command cinder show retrun volume_type is None too.

I think this is not a problem, if you want to have a default volume type, you can set this default volume type in the cinder.conf configuration file, set default_volume_type = <volume_type_name>, the volume you create will be accompanied by a volume type id.
