Hi all!
At the summit during crossproject HA session there were multiple Cinder issues
mentioned. These can be found in this etherpad:
https://etherpad.openstack.org/p/kilo-crossproject-ha-integration
Is there any ongoing effort to fix these issues? Is there an idea how to
approach any of them

Hi,
In Kilo cycle [1] was merged. It started passing AZ of a booted VM to Cinder to
make volumes appear in the same AZ as VM. This is certainly a good approach,
but I wonder how to deal with an use case when administrator cares about AZ of
a compute node of the VM, but wants to ignore AZ of vol

Hi,
If I recall correctly your Horizon-based solution won't be possible, because of
how Nova's code works internally - it just passes Nova's AZ to Cinder API,
without allowing to overwrite it.
We're discussing this particular issue in another ML thread

Right now we’re working on refactoring current TaskFlow implementations in
Cinder to make them more readable and clean. Then we’ll be able to decide if we
want to get more TaskFlow into Cinder or step back from using it. Deadline for

Hi,
In Cinder we had merged a complicated piece of code[1] to be able to return
something from flow that was reverted. Basically outside we needed an
information if volume was rescheduled or not. Right now this is done by
injecting information needed into exception thrown from the flow. Another

There’s also some similar situations when we actually don’t lock on resources.
For example – a cgsnapshot may get deleted while creating a consistencygroup
from it.
From my perspective it seems best to have atomic state changes and state-based
exclusion in API. We would need some kind of

I'm also experiencing some difficulties with Gerrit email notifications. Around
the time Kilo was released it became unreliable. Some notifications are coming
after few days, some of them instantly. In particular I'm often receiving
comments on a patch in invalid order.

Hi all,
I was working on spec[1] and prototype[2] to make Cinder to be able to resume
workflows in case of server or service failure. Problem of requests lost and
resources left in unresolved states in case of failure was signaled at the
Paris Summit[3].
What I was able to prototype was to res

Hi,
With Cinder master being open for Pike development I ask not to merge

Cinder is lacking ZeroMQ messaging support in multibackend
configurations. This is due to the fact that we're abusing
``Target.server`` property by appending "@backend" suffix to the
hostname. This works just fine in RabbitMQ, as it routes messages using
queue names, but fails in ZeroMQ when '
