Hi Jay,
I know about this way :-) but Pike introduced ability to resize attached
volumes:
"It is now possible to signal and perform an online volume size change
as of the 2.51 microversion using the|volume-extended|external event.
Nova will perform the volume extension so the host can detect its new
size. It will also resize the device in QEMU so instance can detect the
new disk size without rebooting." --

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.
