Delete a creating status volume

Hi,

I tried without result create two volumes, I think I know why neither of them were created, but the problem now is that I can't delete them:

euca-describe-volumes
VOLUME vol-00000001 1 nova creating (miproyecto, None, None, None) 2011-04-08T10:17:22Z
VOLUME vol-00000002 1 nova creating (miproyecto, None, None, None) 2011-04-08T10:24:00Z

euca-describe-volumes | grep vol- | cut -f2 | xargs -n1 euca-delete-volume
ApiError: ApiError: Volume status must be available
ApiError: ApiError: Volume status must be available

Any suggestion will be much appreciated

Bye
