Hi,

I have a setup with Openstack Havana on ubuntu precise with multiple schedulers and volumes. root@opstck10:~# cinder service-list +------------------+----------+------+---------+-------+----------------------------+ | Binary | Host | Zone | Status | State | Updated_at | +------------------+----------+------+---------+-------+----------------------------+ | cinder-scheduler | opstck08 | nova | enabled | up | 2014-02-12T10:08:28.000000 | | cinder-scheduler | opstck09 | nova | enabled | up | 2014-02-12T10:08:29.000000 | | cinder-scheduler | opstck10 | nova | enabled | up | 2014-02-12T10:08:28.000000 | | cinder-volume | opstck01 | nova | enabled | down | 2014-02-12T09:39:09.000000 | | cinder-volume | opstck04 | nova | enabled | down | 2014-02-12T09:39:09.000000 | | cinder-volume | opstck05 | nova | enabled | down | 2014-02-12T09:39:09.000000 | | cinder-volume | opstck08 | nova | enabled | up | 2014-02-12T10:08:28.000000 | | cinder-volume | opstck09 | nova | enabled | up | 2014-02-12T10:08:28.000000 | | cinder-volume | opstck10 | nova | enabled | up | 2014-02-12T10:08:28.000000 | +------------------+----------+------+---------+-------+----------------------------+

When I am trying to create a new instance from a volume snapshot it keeps choosing for the creation of the volume opstck01 for which cinder-volume is down.

Did anyone encounter the same problem?

Thanks

I receive the answer from John Griffith. Here it is: "Which node is the parent volume and snapshot on? In the case of create from source-volume and create from snapshot these need to be created on the same node as the source or snapshot." opstck01 was chosen to create the volume because it was the parent of the snapshot.
