cinder list returns different output dependent on api called

[Mike Mason]

When osapi_max_limit is set in cinder.conf, the return amount will change dependent on API called. With the V1 API the vale set in the cinder.conf will be returned, while in V2 it will loop around the max limit until there is nothing to return.

ubuntu@devstack:~$ cinder --version
1.2.2
ubuntu@devstack:~$ grep osapi_max /etc/cinder/cinder.conf
osapi_max_limit = 5

ubuntu@devstack:~$ cinder --os-volume-api-version 1 list

With Kilo (2015.1.0) this is not reproducible

Will try later with devstack at ubuntu

Two things here:

1) Looks like the behaviour Mike Mason reported is the expected one,
See https://review.openstack.org/#/c/134133/
        https://bugs.launchpad.net/cinder/+bug/1342192

2) Fix described in point 1, should be present in 2015.1.0 but it looks like it is not (see my previous comment)

Automatically unassigning due to inactivity.

[Scott DAngelo (scott-dangelo)]

See:

https://review.openstack.org/#/c/134133/

This is not supported in V1 API and it is deprecated, so I don't think there's a feasible way to fix this.
