Detach the volume, then resize it, then re-attach.

Colleagues,
can't find ways to resize attached volume. I'm on Pike.
As far as I understand, it required to be supported in Nova, because
Cinder need to check with Nova whether it's possible to extend this volume.
Well,
- Nova's API microversion is 2.51, which seems to be enough to support
"volume-extended" API call
- Properties of image are *hw_disk_bus='scsi'* and
*hw_scsi_model='virtio-scsi'*, type bare/raw, located in Cinder
- hypervisor is KVM
- volume is bootable, mounted as root, created as snapshot from Cinder
volume
- Cinder's backend is CEPH/Bluestore
and both "cinder extend" and "openstack volume set --size" returns
"Volume status must be '{'status': 'available'}' to extend, currently
in-use".
I did not find any configuration options neither in nova nor in cinder
config files, which can help with this functionality.
What I'm doing wrong?
Thank you.
